Zepoxy REH 140-LVD
Zepoxy REH 140 is a medium viscosity reactive polyamide with high imidazoline content used as a curing agent 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 140 shows good curing behavior in thin film bond lines giving tough and high mechanical strength bonds as it has excellent compatibility with epoxy resins. It is specially used in solvent-based anti-corrosion coatings and shows compatibility with wide range of solvents normally used in epoxy-based coatings. The coatings based on Zepoxy REH 140 are relatively more chemical resistant and lower in viscosity compared to Zepoxy REH 125 and Zepoxy REH 115 based coatings. It is due to these properties it finds use in various applications.
Product Description
Zepoxy REH 140-LVD is a medium viscosity epoxy hardener for Liquid Epoxy Resin (LER) such as Zepoxy RER 128 which provide rapid curing at ambient as well as at low temperatures. Zepoxy REH 140-LVD shows good curing behavior in thin fifilm bond lines giving tough and high mechanical strength bonds as it has excellent compatibility with epoxy resins.
