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.

Formulation useful in several coating application areas follow :

DECORATIVE COATING

1. Decoupage
   A popular application for epoxies is in decoupage type coatings where objects such as wooden plaques,clocks, pictures and signs are coated with a high gloss finish. JEFFAMINE are ideally suited for this application, providing clear, blush freee, glossy, solvent free, high build coatings.

RHEOLOGY MODIFIER

Anionic rheology modifiers are water based acrylic polymer fomulaton that enhance the flow characteristics of liquid by acting as thickeners and stabilizers. These products are formulated as milky white liquids with mild odor. 

Anionic rheology modifier are used in household and institutional formulations to improve product stability and flow quality. Applications include product for dishwashing, laundry, cleaning, floor polishes, paint strippers, car polishes, drain cleaners.  

Anionic rheology modifiers are acrylic polymers suspended in water. If released to the environment , the polymers would be expected to be inert.

PEKTIN BAHAN PENGGANTI GELATIN

Pektin adalah senyawa polisakarida kompleks yang yang terdapat dalam dinding sel tumbuhan dan dapat di temukan dalam berbagai jenis tanaman pangan.
komponen utama dari senyawa pektin adalah asam D-galakturonat tetapi terdapat juga D-galaktosa, L-arabinosa, dan L-ramnosa dalam jumlah yang beragam dan kadang terdapat gula lain dalam jumlah kecil. 

Sifat-sifat Pektin


  • Pektin bersifat asam dan koloidnya bermuatan negatif karena adanya gugus karbosil bebas,
  • Pektin dapat laru dalam air, alkali dan dalam asam oksalat tergantung pada kadar metoksil yang di kandungnya
  • Pektin mempunyai kemampuan untuk membentuk gel jika di campur dalam larutan yang mempunyai tingkat keasaman dan kadar gula dalam perbandinganyang tepat.
  • Dll.

Sifat kimia pectin yang dapat mengikat air sering digunakan sebagai bahan perekat/ pengental ( gelling agent ), untuk proses pembuatan yogurt, jelly buah, selai . Sebagai bahan pengisi komponen permen, serta sebagai stabilizer untuk jus buah dan minuman dari susu, juga sebagai sumber serat dalam makanan. Kini produsen obat-obatan telah menggunakan pectin sebagai salah satu bahan obat.

Penambahan pectin pada minuman berprotein dapat mencegah pengendapan. Pektin adalah ikatan linier dari asam poligalakturonat dengan gugus metil ester yang memiliki muatan negative yang akan mengikat muatan positif NH3+ dari protein. Molekul pectin tersebut akan melindungi protein dan akan menutupi secara langsung permukaan protein, sehingga molekul pectin dapat mencegah pengendapan protein. 

Pektin biasa digunakan pada pembuatan marmalade dan jelly, Gel akan terbentuk pada kondisi pH 2.9-3.5 dan 58-75 % sukrosa serta pectin < 15. Pektin juga digunakan pada pembuatan ice cream. Pektin dan gum merupakan turunan dari gula yang biasa terdapat pada tanaman. Jumlahnya kecil dibandingkan karbohidrat lain. Pektin dibentuk oleh satuan-satuan gula dan asam galakturonat yang lebih banyak dari pada gula sederhana, biasanya terdapat pada buah-buahan serta sayuran. 

Pektin larut dalam air, terutama air panas, sedangkan dalam bentuk larutan koloidal akan berbentuk pasta. Jika pectin dalam larutan ditambah gula dan asam akan terbentuk gel. Prinsip inilah yang digunakan dalam pembentukan gel pada pembuatan selai dan jelly buah-buahan.

Manfaat dan kegunaan PEKTIN, yaitu:


  • Dalam industri makanan, pektin di gunakan dalam pembuatan produk jam, jelly, pengental sari buah, pembuatan permen, emulsi flavour, saos salad dan zat pengemulsi.
  • Dalam bidang kesehatan, pektin bermanfaat sebagai obat penyakit diare dan juga dapat menurunkan kadar kolesterol dalam darah.
  • Dalam industri karet sebagai pengental lateks, memperbaiki warna, konsistensi, kekentalan, dan stabilitas produk yang dihasilkan, dll.
