Overview

HYH253M is a thermosetting novolac phenolic hardener with excellent compatibility with epoxy resins. HYH253M contains built-in accelerator and leveling agent. Powder coatings prepared together with bisphenol A epoxy resins feature fast curing speed. The cured films possess outstanding solvent resistance, chemical resistance and mechanical properties. The reaction between HYH253M and epoxy resin is an addition reaction. No volatile substances are released during powder curing, preventing pinholes and blisters. It is suitable for metal anti-corrosion powder coatings.
