Product Description:
WynCoat^® SL-7210 Silicone Additive is a primary hydroxyl-functional polydimethyl siloxane polyoxyethylene copolymer.

• SL-7210 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 antiblocking and softness. It also improves the mar resistance of certain coatings.
• Improves wetting, leveling and spread-out.
• Goodcompatibility 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 increases hydrolytic stability of the resin.
