摘要:
A plastic article is provided wherein a plastic substrate is coated with multiple resin layers including a primer layer comprising a polymer having a UV-absorptive functional group incorporated therein and a weather resistant hardcoat layer comprising a reaction product of alkoxysilyl-containing benzophenone and/or a hydrolyzate thereof.
摘要:
A coated member includes a resinous substrate, a primer layer, and a hard coat layer. The primer layer is formed on a surface of the resinous substrate, and is composed of a resinous primer. The hard coat layer is formed on the primer layer, and contains a flexibility-imparting agent. At least one of the primer layer and the hard coat layer further contains an ultraviolet ray-absorbing agent. The coated member exhibits good weatherability, adhesiveness and crack resistance.

A silicone coating composition comprising (A) a silicone resin resulting from (co)hydrolytic condensation of an alkoxysilane or a partial hydrolytic condensate thereof, (B) an aromatic-free compound for curing the silicone resin, and (C) a solvent remains stable during shelf storage. It is applied and heat cured to a plastic substrate to form a protective coat having a high hardness, mar resistance, adhesion, toughness and crack resistance.
摘要:
An organic resin laminate comprising an organic resin substrate and a multilayer coating system thereon has UV-shielding property and high mar resistance. The multilayer coating system includes an outermost layer (I) resulting from plasma polymerization of an organosilicon compound, a lower layer (II) of a silicone coating composition comprising composite oxide nanoparticle dispersion, silicone resin, curing catalyst, and solvent, and optionally a bottom layer (III) of acrylic resin.
摘要:
A multi-functional (meth)acrylate compound containing at least three F atoms and at least three Si atoms per molecule is provided. A photocurable resin composition comprising the compound can endow support substrates with antifouling properties with respect to organic stains such as oil mist and fingerprints, without detracting from surface mar resistance.
