SA2830 Hardener for epoxy powder coatings

Curing agent or crosslinking is the mechanism in which a functional entity (single molecule or functionality part of an oligomer, pre-polymer or polymer) reacts during the polymerization process with the other elements to be incorporated in the new polymer chains system.There are various crosslinking methods, and curing agents that can improve the polymerization mechanism. Sometimes, curing agents are absolutely required to reach the final coating’s characteristics. Between all the varieties of crosslinking chemistries, learn how to select the best curing agent for your coating formulations.With the R&D and applicant experience in China, we come up with series of Kabasph curing agent or harder for Epoxy resin, polymer resin, hybrid, polyurethane and so on!
