TP41 Epoxy Hardener For 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.
