Zepoxy REH 125

Zepoxy REH 125 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 125 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. Coatings based on Zepoxy REH 125 are relatively more chemical resistant and lower in viscosity than Zepoxy REH 115 based coatings. It is due to these properties it finds use in various applications.

APPLICATIONS

Solvent based maintenance coatings
Metal primer and enamel paints
Primers, sealers and coatings for concrete
Marine and industrial protective coatings
Tank and pipe linings
Adhesives

BENEFITS

Good chemical and corrosion resistance
Good water resistance
Good pigment and substrate wetting
Good adhesion
