Silicone Feeling Assitant for Polyurethane Leather

Product Name: Silicone Feeling Assitant for Polyurethane Leather
Item No.: SilibaseLE-3019H
Overview of Characteristics:
● ABA silicone SPE can be used to modify polyurethane resin
● ABA-type hydroxyl-terminated organosilicon polyether, after modification, gives the organic resin a strong feel. The intermediate silica chain of polyurethane has enough length, so it gives polyurethane better cold resistance and smooth handle.
Performance: Give the resin a dry and slippery feel.
Characteristic:
● SilibaseLE-3019H Silicone Feeling Assitant for Polyurethane Leather 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 silicone part is particularly large, it can better reflect the characteristics of smoothness, softness, cold resistance, wear resistance and adhesion resistance than other reactive silicone oils.
● SilibaseLE-3019H Silicone Feeling Assitant for Polyurethane Leather is also a good choice for PU resins with slippage and compatibility (solubility in DMF solvents 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:
● SilibaseLE-3019H Silicone Feeling Assitant for Polyurethane Leather can be used for the copolymerization reaction in proportion. The addition amount is generally 0.3-1.5%.
● For post-addition, pre-dilution is needed before adding to the system. The addition amount is 0.5-3.0%.
