Zepoxy REH 145 / 145M are medium viscosity reactive polyamides with high imidazoline content used as curing agents for liquid or solution grade epoxy resins such as Zepoxy RER 128 or Zepoxy RER 011 X 75 to produce room temperature curable adhesives and coatings. Zepoxy REH 145 / 145M shows good curing behavior in thin film bond lines giving tough and high mechanical strength bonds as they have excellent compatibility with epoxy resins. Zepoxy REH 145 has a long pot life while Zepoxy REH 145M has a shorter pot life..

- Potting, casting, and encapsulation
- Synthetic flooring systems
- Maintenance coatings
- Tank and pipe linings
BENEFITS
- Good corrosion resistance
- Good water resistance
