High-quality polyurethane binders are essential for producing durable and long-lasting sports surfaces. Whether used for playgrounds, running tracks, fitness areas, or recreational flooring, a reliable polyurethane binder ensures strong adhesion between rubber granules while providing excellent flexibility and weather resistance.

YN1011 is a one component MDI based polyurethane binder specifically developed for bonding EPDM, SBR, and butyl rubber granules. The solvent-free formulation offers outstanding processing performance while producing resilient and environmentally friendly sports surfaces.

what is PU binder for ePDM

YN1011 is a moisture curing polyurethane resin based on aromatic MDI prepolymer technology. It cures by reacting with moisture in the atmosphere without requiring additional hardeners or catalysts.

The product combines excellent bonding strength with stable curing performance, making it suitable for both manual installation and automated production of sports flooring systems.

Its balanced viscosity allows easy mixing with rubber granules while providing sufficient working time during installation.

Features
