Abstract

A method of producing a scratch resistant coating on a plastics substrate (18) comprising providing a resin material, mixing the resin with a glass filler material causing the resin and glass mixture to form the coating (17) on the substrate (18) in a mould (10), whereby the coating can be produced by an in-mould coating technique which does not involve dip, brush or spray coating of a substrate. Use of the method in the production of translucent components such as vehicle headlamp lenses and windows.
