Product Name: PU Leather Resin Modifier Item No.: SilibaseLE-3019 Description: ● Give the resin a dry and slippery feel ● ABA-type hydroxyl-terminated organosilicon polyether, after modification, gives the organic resin a strong feel. Due to the enough length of the silica-oxygen chain in the middle, polyurethane is endowed with better cold resistance and smooth handle. Functional Groups: ABA Silicone SPE Characteristic: ● SilibaseLE-3019 PU Leather Resin Modifier is a polydimethylsiloxane polyether copolymer with 100% primary hydroxyl group. The functional group is only at the end of the molecular chain and is designed as a modifier of organic resin. Because the middle part of silicone is very large, SilibaseLE-3019 PU Leather Resin Modifier can reflect the characteristics of smoothness, softness, cold resistance, wear resistance and adhesion resistance better than other reactive silicone oils. ● SilibaseLE-3019 PU Leather Resin Modifier is also a good choice if it is used as a post-PU resin additive, considering both slippage and system compatibility (solubility in DMF solvent and good solubility in toluene, butyl ester and butanone). Technical Indicators: ● Appearance: Yellow to amber translucent viscous liquid ● Active substance content: >98% ● Viscosity (25℃): ≥10000CP Suggested Dosage and Use Method: ● It can be used for the copolymerization and proportionate addition reaction. The addition amount is generally 0.3-1.5%. ● For post-addition, pre-dilution is needed before adding to the system, and the addition amount is 0.5-3.0%. Packaging Specifications: 25kgs/drum or 200kgs/drum Validity: 720 days Dangerous Goods Marking: Common Goods
