A polycarbonate article having an adherent mar, abrasion and chemical resistant ultraviolet light cured coating on the surface thereof comprised of the photoreaction products of certain polyfunctional acrylate monomers and certain acrylate modified polymers.

Photocurable acrylic coated polycarbonate articles

A method is provided for making abrasion resistant, non-opaque thermoplastic articles, for example, silicone-coated polycarbonate sheet useful as glazing material. A mixture of a certain UV absorber, for example a cyanoacrylate, and light stabilizer, such as a piperidine derivative, has been found to impart improved weathering resistance to the silicon-coated thermoplastic articles when used as part of an acrylic primer coating between the silicone top coat and the thermoplastic substrate.

Abrasion resistant silicone coated thermoplastic article and method for

A shaped, non-opaque coated polycarbonate article having improved abrasion and chemical solvent resistance comprising a polycarbonate substrate having disposed on the surface thereof a non-opaque primer layer of controlled thickness comprised of a thermoset acrylic polymer and disposed on said primer layer a non-opaque top coat comprised of a thermoset organopolysiloxane.

Abrasion resistant silicone coated polycarbonate article

A shaped, non-opaque coated polycarbonate article having improved abrasion and chemical solvent resistance comprising a polycarbonate substrate having disposed on the surface thereof a non-opaque primer layer of controlled thickness comprised of a thermoset acrylic polymer and disposed on said primer layer a non-opaque top coat comprised of a colloidal silica filled thermoset organopolysiloxane.

A polycarbonate article having a durably adherent mar, abrasion and chemical resistant UV cured coating on the surface thereof comprised of the photoreaction products of (i) certain polyfunctional acrylate monomers and (ii) resorcinol monobenzoate.
