PPC HFST: High Friction Surface Treatment

Improves coefficient of friction to reduce crashes in horizontal curves and intersections View Demo View Projects

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.

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

Restores friction

Exceeds the requirements of most high friction surface treatment (HFST) specifications

Superior adhesion

Excellent adhesion to asphalt and concrete pavements

Rapid return to service

Rapid 2 hour cure time after placement, even in conditions below 40ºF
