       Information

Principal Description:
50% solids aqueous solution of modified polyamine adduct as waterborne epoxy hardener. Capable of emulsifying and curing liquid resins (or included epoxy diluents) without added surfactants. Has low viscosity, light color, appropriate pot-life. Cures showed good color and surface gloss, high hardness and flexibility as well as adhesion suitable to coat on damp/green concrete surface. Also offers longer pot-life and better flexibility by using the formulations based on liquid/semi-solid/solid resin dispersions.

Principal Applications:
Waterborne decorative coatings, epoxy mortars and adhesives for floors, walls and other concrete structures etc. Also applications in civil engineering, containers, mechanical equipments and general industrial areas.
