Synthetic Leather Modifying Additive Delivers excellent cold resistance and a smooth hand feel.
Product Description
WynCoat® SL-5019 is a reactive organosilicon with primary hydroxyl groups at both ends, used for copolymerization modification with polyurethane. Due to the sufficient length of its intermediate silicon oxygen chain, it endows polyurethane with better cold resistance and a smooth feel.
Key Features and Benefits：
WynCoat® SL-5019 is a polydimethyl siloxane polyether copolymer with hydroxyl functional group located only at the molecular chain end, designed as a modifier for organic resins. Due to the particularly large organic silicon portion in the middle, it can better reflect related characteristics such as smoothness, softness, cold resistance, wear resistance and anti sticking compared to other reactive silicone products. If WynCoat® SL-5019 is added after PU resin, it takes into account both smoothness and system compatibility (with a certain solubility in DMF solvent and good solubility in toluene, butyl ester, and butanone), and is also a good choice.
