PPC HFST, the polyester resin based high friction surface treatment (HFST) is designed to improve coefficient of friction to reduce crashes in horizontal curves and intersections as well as to provide lane demarcation. PPC HFST offers two hour traffic return in a variety of conditions.
High friction surface treatment is a cost effective solution that dramatically and immediately reduces crashes, injuries and fatalities.
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
Exceeds the requirements of most high friction surface treatment (HFST) specifications
Excellent adhesion to asphalt and concrete pavements
Rapid return to service
Rapid 2 hour cure time after placement, even in conditions below 40ºF
