       Information

Principal Description:
80% solids aqueous solution of modified polyamine adduct as non-ion waterborne epoxy hardener. Capable of emulsifying and curing liquid resins (or included epoxy diluents) without added surfactants. Low viscosity, long pot-life and high performance/price ratio. Cures showed good surface gloss and color stability, 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, and gets good chemical and corrosion resistances.

Principal Applications:
Waterborne coatings, primers, mortars and adhesives for floors, walls and other concrete structures etc. Also suitable for low VOC metal anti-corrosive waterborne coatings, such as marine, bridge, pipeline, chemical equipments and general industrial areas.
