Composition: Carbon Hydroxyl Modified Polydimethylsiloxane
TPD-4050 has active carbon hydroxyl structure, which can react with organic polymers (such as polyester, polyurethane, acrylic resin, epoxy resin, melamine resin, etc.) to improve the mixing processability, leveling, demoulding, gloss, lubricity, heat resistance, cold resistance, weather resistance and hydrolysis resistance of organic polymers. It will help to keep the coating smooth and bright with durability.
