FAQs
A PU Binder is a polyurethane-based adhesive resin designed to bind rubber granules or other materials into a unified surface or product.
PU Binders enhance bonding strength, elasticity, weather resistance, and long-term durability in surfaces like EPDM tracks, playground floors, and rubber tiles.
Yes — cured PU Binder stands up to UV rays, rain, temperature changes, and humidity, making it suitable for outdoor applications.
It cures through moisture in the air and substrate; curing speed depends on ambient temperature and humidity.
Yes — our single-component PU Binders are solvent-free and form a very thin, strong film once cured.
