Choose Your Binder

Aromatic Polyurethane Binder

A cost-effective option for everyday rubber flooring applications. Models: MDI-88, MDI-6117. Aromatic binders may develop a temporary yellow tint under strong UV exposure. This can gradually reduce with normal surface wear.

Aliphatic Polyurethane Binder

A premium transparent binder with superior UV resistance. It helps preserve rubber color and minimize discoloration. Model: HDI-10. Recommended for blue, gray, white, and other colors requiring long-term stability.
