Technical Datasheet

Zepoxy REH 120

Zepoxy REH 120 is a high viscosity reactive polyamide used as curing agent for liquid or solution grade epoxy resins such as Zepoxy RER 128 to produce room temperature curable adhesives and coatings. Systems based on Zepoxy REH 120 impart higher flexibility, tack, and adhesion compared to systems based on other polyamides

APPLICATIONS

Metal and plastic adhesives
Highway and bridge deck repairs
Potting, casting, and encapsulation
Synthetic flooring systems
Maintenance coatings
Tank and pipe linings

BENEFITS

Good corrosion resistance
Good pigment and substrate wetting
Good adhesion
