Product Details
WynCoat® SL-4160 silicone additive is a primary hydroxyl-functional polydimethyl siloxane polyoxyethylene copolymer.
Key Features and benefits
● SL-4160 is a block co-polymer that can be added to organic components to improve surface properties.
● When used as an additive in organic textile coatings, it imparts antiblocing and sofeness. It also improves the mar resistance of certain coatings.
● Improves wetting, leveling and pread-out.
● Good compatibility with PU resin and provide great anti-sticking property.
● Endblocking glycol contains active hydroxyl group, which is reactive with organic polymers like polyurethane. Therefore, it is chemically reacted in the network and increase hydrolytic stability of the resin.
