Application
Siwin-OHR3667 is a linear copolymer of polydimethylsiloxane and polyoxyethylene with primary hydroxyl functional groups at both terminals. It is developed as a modifier for organic resins to improve the smoothness and anti-blocking property of resins, and also delivers certain leveling performance. It is used for modification of organic resins, especially polyurethane, to improve the flow and leveling property of resin coatings. It can enhance the air permeability of synthetic leather, and provide anti-blocking, release-assisting, crater inhibition, anti-mottling and anti-floating effects, as well as improve gloss.
