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.
