HW (High Wear) Surface Coat HT (High Temp)
Description:HW Surface Coat HT was developed to meet the exacting requirements of modern tooling applications. Developed for high temperature applications at or above 350 F ( 170 C), HW Surface Coat HT has demonstrated superior performance in autoclave prepreg fabrication. HW Surface Coat HTs high temperature dimensional stability through repeated high temperature cycles has given fabricators a new degree of flexibility in high-performance construction. For best results apply with a brush at ~ 15-20 mil thickness. Material Handling Properties:
