Smoothing and scratch resistant silicone itself does not have good wear resistance. When it has a low coefficient of friction it becomes very smooth and scratch-resistant. Smexing and scratch resistant additives generally use silicone polyether copolymer, waterborne coatings also use high molar mass of hydroxy silicone oil emulsion.
Brightener silicone polyether methacrylate copolymer, hydroxyl terminated ABA type silicone polyether (EO) and hydroxyl terminated silicone polyether (EO/PO) can be used as UV type coating brightener due to their characteristics of reducing friction coefficient and good gloss.
Adhesion promoters Adhesion promoters are basically silane coupling agents. The glass substrate mainly uses γ-epoxy propoxy trimethoxy silane, N- (β-aminoethyl) -γ-aminopropyl trimethoxy silane 50% butanol solution; Metal substrates mainly use γ-epoxy propoxy trimethoxy silane; Plastic substrates mainly use N- (β-aminoethyl) -γ-aminopropyl trimethoxy silane and methacryloxypropyl trimethoxy silane.
