PPC HFST: High Friction Surface Treatment
Improves coefficient of friction to reduce crashes in horizontal curves and intersections
PPC HFST, the polyester resin based high friction surface treatment (HFST) is designed to improve the coefficient of friction to reduce crashes in horizontal curves and intersections.
High friction surface treatment is a cost effective solution that dramatically and immediately reduces crashes, injuries and fatalities.
Features
Simple Application
Simplified stoichiometry reduces concerns with mix ratio. Can be applied with current automated installation equipment or can be mixed by hand for smaller high friction surface treatment installations
