silicone resin modifier for polyurethane leather

product name: silicone resin modifier for polyurethane leather
item no.: silibasele-3520
sketch of silibasele-3520 silicone resin modifier for polyurethane leather:
● copolymerization with polyurethane resin can provide moisture permeability and hydrophobicity for polyurethane synthetic leather.
● hydroxyalkyl-terminated organosilicon, copolymerized with organic grease, can provide moisture permeability and hydrophobicity for organic resins.
functional groups: ch2oh
product performance:
● resistant marker pen, anti-graffiti effect. modified polydimethylsiloxane for solvent-based anti-graffiti paint, with additional peeling effect.
● polyurethane prepolymer reacts with polyurethane to introduce silicone into the main chain of polyurethane, which makes polyurethane resin soft, cold-resistant and smooth.
