Flexibuild is a non-isocyanate polyurethane which dries by solvent evaporation to a highly elastomeric film with excellent adhesion properties on flexible substrates. Flexibuild is intended for use on non metallic substrates which are subject to movement such as PVC, PU elastomer, rubber variants, fabrics, leather etc. It can also act as an adhesion promoting tie-coat on a variety of substrates including some difficult plastics. Flexibuild offers a higher gloss and thicker films compared to Flexithane. The two are compatible.
