Zepoxy REH 205
Zepoxy REH 205 is an industrial-grade epoxy hardener formulated for epoxy systems requiring efficient curing, reliable adhesion, and durable mechanical strength. Its advanced formulation supports strong chemical resistance and dependable performance across demanding industrial and commercial applications. The product contributes to improved bonding efficiency and long-lasting surface protection in epoxy flooring, coating, and adhesive systems. Zepoxy REH 205 is suitable for maintenance projects, repair compounds, laminates, and industrial epoxy applications where consistent curing characteristics and structural durability are essential.
Zepoxy REH 205
Low Viscosity Modified Cycloaliphatic Amine Curing Agent
Zepoxy REH 205 is a low viscosity, low color 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.
When formulated appropriately with epoxy resin it gives clear, air free, glossy surfaces. It also provides
resistance to a variety of chemicals such as acids, alkalis, hydrocarbons, and water.
Zepoxy REH 205, being cycloaliphatic, also provides excellent weather resistance.
It is less irritating, gives low odor, excellent transparency, and light color.
APPLICATIONS
- Solvent-free, high solids coatings
- Self-leveling floorings
- Primers and screeds
- Transparent coatings
- Chemical resistant mortars and linings
