WynCoat® SL-4162 is a primary hydroxyl-functional polydimethyl siloxane polyoxyethylene copolymer with ABA type of polydimethylsiloxane polyether block copolymer,.

Key Features and Benefits:
  • SL-4162 is a block co-polymer that can be added to organic components to improve surface properties.
  • When used as an additive in organic coatings, it imparts antiblocking and softness. It also improves the mar resistance of certain coatings.
  • Improves wetting, leveling and spread-out.
  • Increase softness, air permeability and moisture permeability; improve abrasion resistance and low temperature flexibility.
  • Endblocking glycol contains active hydroxyl group, which is reactive with organic polymers like polyurethane. Therefore, it is chemically reacted in the network and increases hydrolytic stability of the resin.
