Product Description

TP41 Epoxy Hardener (Heavy anti-corrosion powder)

Description
Epoxy Hardener TP41 is a phenolic curing agent for use with epoxy and epoxy novolac-based powder coatings. Coatings made with TP41 exhibit the excellent chemical resistance, substrate wetting and mechanical properties for which phenolic-cured epoxy coatings are noted. It offers formulators the versatility of using differing cure cycles while maintaining performance properties. For example, powder coatings made with TP41 can be "snap" cured in 2 minutes at 200°C or low-temperature cured in 20 minutes at 120°C while maintaining both mechanical (160 reverse inch pounds impact) and chemical resistance (100+ MEK double rubs) properties. In addition, powder coatings made with TP41 have good package stability and exhibit very low yellowing.
