Abstract
Method of providing a hard-wearing surface on a plastics component consists of grafting the surface with a chemical cmpd. contg. acid groups, and cross-linking it, either simultaneously or subsequently, with a substance which forms polyvalent metal cations. Pref., polyamide is grafted with acrylic acid, then cross-linked with a salt of a bivalent metal, esp. Ca acetate.
