SANMIN 122A EPOXY HARDENER ALTERNATIF PENGGANTI KH 816 ( CYCLOALIPHATIC AMINE )

*SANMIN 122A* adalah senyawa kimia yang sering digunakan sebagai hardener atau kerasan dalam sistem epoxy flooring atau lantai epoxy. Epoxy flooring adalah jenis lantai yang tahan lama, kuat, dan tahan terhadap berbagai jenis kerusakan fisik dan kimia. Untuk mencapai sifat-sifat ini, epoxy flooring memerlukan bahan hardener yang mengeraskan resin epoxy saat proses aplikasi. 

Berikut adalah cara *SANMIN 122A* digunakan sebagai hardener pada epoxy flooring:

Campuran Epoxy Resin: 

*SANMIN 122A* biasanya dicampur dengan resin epoxy komponen utama. Pencampuran ini dilakukan sesuai dengan rasio yang ditentukan oleh produsen epoxy flooring, yang dapat bervariasi tergantung pada jenis dan merek produk tertentu. Perbandingan biasa adalah 2:1 (resin epoxy: *SANMIN 122A*).

Reaksi Kimia: 

Setelah campuran epoxy resin dan *SANMIN 122A*, reaksi kimia dimulai. Proses ini dikenal sebagai reaksi polimerisasi. *SANMIN 122A* berperan sebagai kerasan yang menghubungkan molekul-molekul resin epoxy, membentuk struktur tahan lama yang keras dan padat.

Aplikasi: 

Setelah campuran terbentuk, epoxy flooring ini kemudian diaplikasikan ke permukaan yang telah disiapkan. Aplikasi ini biasanya dilakukan dengan menggunakan spatula atau alat khusus yang memungkinkan untuk menyebarkan lapisan epoxy secara merata di seluruh permukaan.

Pengeringan dan Kerasan: 

Setelah diaplikasikan, lapisan epoxy membutuhkan waktu tertentu untuk mengering dan mengeras sepenuhnya. Waktu pengeringan dan kerasan dapat bervariasi tergantung pada suhu, kelembaban, dan jenis epoxy yang digunakan. Biasanya, epoxy flooring akan mencapai tingkat kerasan yang sesuai dalam beberapa hari setelah aplikasi.

*SANMIN 122A* digunakan sebagai bahan hardener pada epoxy flooring karena kemampuannya untuk berpartisipasi dalam reaksi kimia yang membentuk jaringan polimer padat dan keras. Ini memberikan lantai epoxy kekuatan, ketahanan terhadap aus, tahan terhadap kimia, dan permukaan yang mudah dibersihkan. Penting untuk mengikuti petunjuk dari produsen epoxy flooring dan mengikuti prosedur aplikasi yang benar untuk mencapai hasil yang optimal dan menjaga tingkat keselamatan yang tinggi selama proses aplikasi.

JEFFAMINE APPLICATION

FLOORING, TROWELING and MORTARS

An important application are for Jeffamine D 230 is their use in highly filled epoxy formulations for industrial or decorative floor coatings. There are two primary types of epoxy flooring systems: Self leveling and trowel coverings. Epoxy flooring can be as simple as a thin film clear or lightly pigmented formulation or a series of build up coating layers. However, most epoxy floors today consist of several coats, which usually include at least a base coat, mid coat and glaze or topcoat.

Self leveling flooring have lower filler contents ( less than 4:1 filler to epoxy binder ), permitting the material to be spread over the substrate, usually concrete, to a thickeness of about 1/8 inch. Such binder rich flooring are more chemically resistant. Skid or slip resistance may be improved by broadcasting sand or other mineral fillers over the top of the floor prior fo final curing.

Trowable floorings generally are more highly filled ( 6-8:1 filler to binder ratios ) with a coarse mineral filler, such as quartz and / or silica sand. These higher filler loadings lead to outstanding abrasion resistance, coupled with excellent mechanical strength. Such systems are usually screeded or troweled over the substrate to a thickness of 1/4 inch or less.

A special type of synthetic epoxy surface is the pebble finished system, where decorative river rock is used as the filler at levels of 10-15:1 over the epoxy binder. In these applications the clear epoxy is also a high gloss coating or decorative glaze for the aggregate material. These systems are sometimes known as decorative aggregate and have been popular for interior and exterior applications in flooring, walkways and swimming pool decks.

The performance of an epoxy based floor system depends on proper selection and formulation of components, as well as adequate substrate surface preparation. The Jeffamine products, along with monononylphenol ( MNP ) have found application in all of the above flooring systems. These are often used in combination with polyamides or cycloaliphatic amine hardeners to achieve desired performance characteristics, which include appearance, chemical resistance, impact resistance and abrasion resistance.

Heavily filled epoxy systems may be used for structural  applications, such as concrete reinforcement. Often referred to as polymer concrete, these materials are used in applications, such as bridge overlays and other areas requiring higher compressive strengths than offered by conventional porland cement concrete. Similar formulations are also used for tile grouting or mortars and concrete repair.

Repair of cracked concrete structures may be accomplished by injection of clear epoxy systems into the areas around the developing crack. This is done by injecting a low viscosity, slow curing epoxy formulation using a syringe delivery into many, finely drilled cavities in the vicinity of the crack. The Jeffamine, such as D 230, D 400, T 403 are ideal for such systems, which have the ability to saturate deep into the concrete matrix before the  epoxy matrix begins to gel and finally set or cure. This practice of crack injection has been used in the repair of concrete building, bridges, railroad ties, and dams.

All of the above described applications fall into the broad category of construction, or civil engineering. Aside from surface coatings and adhesives, materials included would be the " synthetic " concretes, mortars, grouts, and putties. Such materials certainly find extensive use in new construction and various civil engineering applications; and for patching and repair, they have no peer. Several specific examples follow.


SURFACE COATING FORMULATIONS

SURFACE COATING
The properties of JEFFAMINE curatives lend themselves to the preparation of excellent coatings and protective finishes. Epoxy coatings cured with JEFFAMINE products are flexible , tough, and resistant to impact and abrasion. They have excellent resistance to blushing compared to other amine hardeners.

EPOXY VS PU FLOORING

Epoxy and polyurethane are great for : 
> Protecting your floor against stains, damage, chemicals, oils, and wear.  
> They are both light reflective, easy to clean, and long lasting.  

EPOXY FLOOR COATING BENEFITS
Epoxy is a thermosetting polymer which is available in three different formulations for : a garage floor coating and sealer : 
1. water based, 
2. solvent based, and 
3. 100% solids.  

These formulations allow for varying degrees of thickness from 3 mils to over 10 mils for a single coating for a garage floor.  They also allow for ease of application, special bonding characteristics, and VOC considerations.  Epoxy bonds extremely well to properly prepared concrete and can sometimes be used as a resurfacing agent for old or worn concrete that needs a new garage floor surface.

The best epoxy formulations are : 

• 100% solids and 
• provide for an extremely hard, thick, and impact resistant surface
• This self-leveling thickness contributes to filling in the small hairline cracks and imperfections of the floor as well as providing protection.  
• It also works well against hot tire pick up, scratching, and wear from abrasion.  

Though some epoxy formulas come with U.V. inhibitors, they will still eventually yellow or amber as the industry calls it when exposed to sunlight for any length of time.  This is something to consider when choosing a garage floor finish.

POLYURETHANE FLOOR COATING BENEFITS

Like epoxy, polyurethane is a thermosetting polymer as well and is considered a high performance coating.  It is commonly known as urethane for short, though that it is technically incorrect and there is actually a big difference between polyurethane and urethane.  If someone is advertising a urethane coating, it is actually polyurethane.

Polyurethane top coat

aliphatic polyurethane is the desired choice for garage floors.  Though they are approximately 60% to 70% solids depending on the manufacturer, a polyurethane coating is only about 2 to 3 mils in thickness and can’t be adjusted as with epoxy.

Aliphatic polyurethane/advantage of polyurethane over epoxy  :

• More flexibility than epoxy and it is this flexibility that aids in absorbing impacts better.  
• Much more abrasion resistant.  ( the wear resistance of polyurethane over epoxy is almost 3 to 1 )
• The resistance to chemicals is better than epoxy as well and this includes resistance to solvents such as methylene chloride which is the primary ingredient in paint stripper.
• U.V. stable ( it won’t yellow like epoxy does when exposed to small amounts of sunlight over a period of time ).  

 can tolerate larger temperature swings, and handles humidity much better.  It is also available in different finishes from satin to very glossy.

Less Advantages 

• The surface of polyurethane is not as hard as epoxy but it is much more scratch resistant,
• It does not bond well to concrete and its thin dry film thickness will not work well as a self-leveling coating to fill in small cracks and divots in the surface.  
• Another consideration is that most polyurethanes are solvent based, meaning they can have high VOC’s,and may require a respirator to apply.
• Polyurethane is also a better medium than epoxy to mix in anti-slip aggregate

JEFFAMINE D 230 as specialthy epoxy curing agent

Jeffamine D-230 polyoxypropylenediamine undergoes reactions typical of primary amines. Jeffamine D-230 polyetheramine is a difunctional, primary amine with an average molecular weight of about 230. The primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chain.

Because of its unique structure, however, Jeffamine D-230 has found its most significant use as an epoxy curing agent. The use of Jeffamine D-230 leads to tough, clear, impact-resistant coatings, castings, and adhesives.
Example include coatings for decoupage and furniture, reinforced composites, electrical encapsulation, and lamination. Coatings made with unmodified Jeffamine D-230 are free of the surface “ blush “ prevalent with many amine curing agents. Jeffamine D-230 has found its way into miniature medical devices, industrial floors, boat construction, decorator clocks, and space vehicles.

Epoxies formulated with Jeffamine D-230 can be readily modified because Jeffamine D-230 is compatible with a wide range of modifiers and curing agents, including other Jeffamine products. Amidation of Jeffamine D-230 with a variety of aliphatic and aromatic carboxylic acids is readily accomplished by known techniques. The resulting poly-amides are of interest as “ hot melt “ adhesives, for example.

As a primary amine, Jeffamine D-230 reacts quickly with isocyanates. The reaction can be managed however, if small quantities are used ( e.g. as a viscosity modifier ) or if quick-mix equipment ( e.g, RIM ) is employed.

Salts may be formed readily which have potential use, e.g, as surfactants and fire retardants. The reactivity of Jeffamine D-230 may be modified by cyanoethylation, a reaction which proceeds readily and cleanly. Polyurea coatings have been made from the cyanoethylated derivative.

APPLICATIONS :
• Epoxy Curing Agent
• Reacts with carboxylic acids to form hot melt adhesives
• Reacts quickly with isocyanates
• Salts may be formed readily for surfactant use

BENEFITS
• Low viscosity, color and vapor pressure

Jual Epoxy Coating for Metal

Steel will rust only if water and oxygen are both present and the rusting process is greatly accelerated by pollutants in the atmosphere, such as sulphur dioxide from the burning of oil, coal, or gas and chlorides from de-icing salts or marine atmospheres. Solid pollutants can be hygroscopic and may promote localised attack (e.g. corrosion pitting) at specific points on exposed steel. Protective systems must be resistant to attack by such pollutants and should be applied only to surfaces from which they have been removed.

To ensure good coating adhesion, it is essential that the surface to be coated is rendered free of dirt, dust and debris that might affect performance. Water-soluble residues, if left on the surface, will cause rapid deterioration at the interface with paint when the coating is exposed to moisture.

Paint is the most commonly used material to protect steel, and in practice the term, ‘paint’ covers a wide range of materials with different properties. The application of paint is comparatively easy with no limitation on the size of steelwork that can be treated.

For structural steelwork the paint film thickness is important for lasting protection since it is difficult to obtain perfect application under construction conditions. Best results are obtained when coatings are applied in heated enclosed workshops; units for bridge structures and building framework can be coated in this manner before erection and additional coats may be applied on site, where required.

EPOXY PRIMERS
Epoxy primers are two-pack materials utilising epoxy resins and usually have either polyamide or polyamine curing agents. They are pigmented with a variety of inhibitive and non-inhibitive pigments. Zinc phosphate epoxy primers are the most frequently encountered and give the best durability within the group.

Epoxy coatings are generally packaged in two parts that are mixed prior to application. The two parts consist of 1) an epoxy resin which is cross-linked with 2) a co-reactant or hardener. Epoxy coatings are formulated based upon the performance requirements for the end product. When properly catalyzed and applied, epoxies produce a hard, chemical and solvent resistant finish. They are typically used on concrete and steel to give resistance to water, alkali and acids.

EPOXY FLOORING VS PU FLOORING

Epoxy floors are harder, more durable and have a much higher compression strength than polyurethanes. This is why they are the preferred choice for heavy duty industries, warehouses and logistics centers with heavy forklift traffic. 

Polyurethane floors are usually softer and more elastic, which makes them more resistant to scratching as their elasticity tends to absorb some of the impact. The elasticity of PU floors also makes them a preferred choice in freezing chambers where the storage temperature can reach -30 degrees Celsius (-22 F). They are also a good choice for multideck car-parks since the elastic coating can act as a waterproofing and crack-bridging layer.

Epoxies and polyurethanes behave differently when exposed to certain chemicals. For example polyurethanes are the preferred choice in food industries that have exposure to lactic acids. This the reason why many food processing companies that work in milk, dairy, cheese production choose polyurethanes. 

Epoxies under such conditions may experience corrosion and yellowing. However when working in industries with sulfuric acids (like battery manufacturing etc) epoxy floors are much more resistant than polyurethanes. If you are working in a facility with heavy exposure to chemicals, check with the manufacturer to see which product is better suited.

Click here to view a table on the chemical resistance properties of epoxy  
http://www.engineeringtoolbox.com/chemical-resistance-epoxy-d_786.html

Epoxy resins are also sensitive to moisture, but the damage done by humidity will be far more limited. Therefore when working in environments where the presence of humidity could be an issue, epoxy is always the much better choice.

Polyurethane floors can be easily modified to extend or limit their pot life, re-coat time as well as the total curing time. This flexibility enables contractors to complete PU floors in a much shorter space of time .With PU you could effectively start a multicoat project on Friday and hand it over on Monday. Epoxy floors are much less flexible in this respect in the sense that they usually require 7 days to fully cure.

In general polyurethanes are harder to work with. Their limited pot life and sensitivity to humidity require very well trained and experienced staff. Personally I refuse to supply inexperienced teams with PU floor resins. Too many things can go wrong.

Finally if you are wondering which one of the two resins is cheaper, I do not really have an answer to that. There are quite a few varieties of products out there. Comparing epoxies to PUs is like comparing apples to oranges. Ultimately your choice of floor should not be based on which one of the two is cheaper, but which one of the two suits your needs.

Benzyl Alcohol dalam formulasi cat epoxy

Benzyl alcohol adalah senyawa organik yang memiliki berbagai aplikasi industri, termasuk dalam formulasi cat epoxy. 

Berikut ini adalah beberapa manfaat dan kegunaan benzyl alcohol dalam bidang cat epoxy:

• Pelarut:
  Benzyl alcohol digunakan sebagai pelarut dalam cat epoxy. Ini membantu melarutkan dan mengencerkan bahan-bahan dalam formulasi cat, sehingga mempermudah pengaplikasian dan penyebaran cat.

• Pengendali viskositas:
  Benzyl alcohol dapat digunakan sebagai pengendali viskositas dalam cat epoxy. Dengan menambahkan benzyl alcohol ke dalam formulasi cat, viskositasnya dapat diatur untuk mencapai konsistensi yang diinginkan. Ini memungkinkan penggunaan cat yang lebih mudah dan aplikasi yang lebih merata.

• Penghambat busa:
  Benzyl alcohol juga dapat berfungsi sebagai penghambat busa dalam cat epoxy. Selama pengadukan atau pengaplikasian cat, udara dapat terperangkap di dalamnya dan menyebabkan pembentukan gelembung udara atau busa. Dengan menambahkan benzyl alcohol ke dalam formulasi cat, kemampuan cat untuk menghambat pembentukan busa dapat ditingkatkan.

• Stabilisator warna:
  Benzyl alcohol juga berfungsi sebagai stabilisator warna dalam cat epoxy. Ini membantu melindungi pigmen atau pewarna dalam cat dari degradasi yang disebabkan oleh panas, cahaya, atau reaksi kimia lainnya. Dengan adanya benzyl alcohol, warna cat dapat tetap stabil dan tidak berubah seiring waktu.

• Pengawet:
  Benzyl alcohol memiliki sifat antimikroba yang dapat menghambat pertumbuhan mikroorganisme dalam cat epoxy. Ini membantu mencegah pembentukan jamur atau bakteri yang dapat merusak cat seiring waktu. Penggunaan benzyl alcohol sebagai pengawet membantu memperpanjang umur simpan cat dan menjaga kualitasnya.
