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 ened 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 |
