latent hardener for PU coating

The latent hardener for PU coating activates under thermal conditions, releasing reactive groups that initiate crosslinking in polyurethane networks. It provides excellent film hardness, gloss retention, and resistance to solvents, abrasion, and UV exposure. This additive ensures controlled curing speed and prevents premature gelation during storage. Compatible with polyester and polyether PU resins, the latent hardener for PU coating ensures smooth curing, high surface quality, and improved durability in industrial coating processes.
