Ressichem Zepoxy REH 7301
Zepoxy REH 7301 is a low viscosity, low color and long pot life modified cycloaliphatic polyamine curing agent for use with liquid epoxy resins such as Zepoxy RER 128 / Di Glycidyl Ether of Bisphenol A (EEW 190) to produce solvent free room temperature curable thermoset coatings and floor toppings of high mechanical strength. When formulated appropriately with epoxy resin it gives clear, air free, glossy surfaces. It also provides resistance to variety of chemicals such as acids, alkalis, hydrocarbons, and water. Zepoxy REH 7301, being cycloaliphatic, also provides excellent weather resistance. It is less irritating, gives low odor, excellent transparency, and light color.
