Wynca® XHG-2540

Organic modified polydimethylsiloxane with end-hydroxymethyl functional group. Acts as release agent, anti marker agent and anti-graffiti agent. In a variety of polyurethane systems, hydroxymethyl can be cross-linked with NCO, so that the introduction of silicone into resin system components for the polyurethane coating provides anti-graffiti and easy cleaning properties. Used for the manufacture of solventborne coating with additional spin-off effect and high efficiency. Recommended dosage level is 1-3%.
