pu leather resin modifier

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%.
