Produktoplysninger

WynCoat® SL-7520 is a primary hydroxyl-functional polydimenthyl siloxane with carbinol terminated. It is used to modify and customize polyurethane (PU) resin. Pu resin is an environmentally friendly polymer material with multiple applications, and is often used in coatings, adhesives, foam plastics and other fields. Adding a PU resin modifier can improve the performance and characteristics of the PU resin, such as enhancing its strength, improving heat resistance, and improving corrosion resistance.
