EPOTEC TH 7302 sebagai epoxy hardener

Epotec TH 7302 is a low viscosity, low colour modified cycloaliphatic polyamine curing agent for use with liquid epoxy resins such as epotec YD 128 to produce solvent free room temperature curable thermoset coatings, floor toppings. When formulated appropriately with epoxy resin it gives clear, air free, glossy surfaces. It also provides resistance to variety of chemicals such as acids, alkalies, hydrocarbons and water. Epotec TH 7301, being cycloaliphatic, also provides excellent weather resistance. It is less irritating, gives low odour, excellent transparency and light colour.


Terjemahan : 

Epotec TH 7302 adalah epoxy hardener jenis poliamina sikloalifatik/cylcoaliphatic dengan viskositas rendah, warna bening yang dimodifikasi untuk digunakan dengan resin epoksi cair seperti epotec YD 128 untuk menghasilkan lapisan termoset yang dapat kering pada suhu kamar bebas pelarut, topping lantai. 

Ketika diformulasikan dengan tepat dengan resin epoksi, permukaannya menjadi bening, bebas udara, dan mengkilap. Ini juga memberikan ketahanan terhadap berbagai bahan kimia seperti asam, alkali, hidrokarbon dan air. Epotec TH 7301, bersifat sikloalifatik, juga memberikan ketahanan cuaca yang sangat baik. Ini tidak terlalu mengiritasi, memberikan bau yang rendah, transparansi yang sangat baik dan warna yang terang.


Application

  • Solvent-free, high solids coatings.
  • Self leveling floorings.
  • Primers and screeds.
  • Transparent coatings.
  • Chemical resistant mortars and linings.
  • Others contruction application.
  • Water proofing.

Deta application used for clear two part epoxy flooring and wood epoxy resin

Deta application used for clear two part epoxy flooring and wood epoxy resin

Diethylenetriamine (abbreviated DETA and also known as 2,2’-Iminodi(ethylamine)[2]) is an organic compound with the formula HN(CH2CH2NH2)2. This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple hydrocarbons. Diethylenetriamine is structural analogue of diethylene glycol. Its chemical properties resemble those for ethylene diamine, and it has similar uses. It is a weak base and its aqueous solution is alkaline.  DETA is a by product of the production of ethylenediamine from ethylene dichloride.

Diethylenetriamine is a yellow liquid with an ammonia-like odor. Less dense than water. Corrosive to metals and tissue. Vapors heavier than air. Burns, although possibly difficult to igntie. Toxic oxides of nitrogen produced during combustion. Used as a solvent for plastics and dyes and in chemical synthesis. Boiling Point 207 DEG C @ 760 MM HG, Melting Point -39 DEG C, Flash Point 101.7 deg C (Open cup), water solubility 1000 mg/mL.
