Abstract
Abstract A process for the production of cross-linked resilient automotive body components having a cured surface coating from a thermoplastic elastomeric composition substantially free from added vulcanizing or free-radical inducing agents comprises: Fabricating an uncured component from said composition; applying to the component a radiation-curable surface coating; and simultaneously curing the surface coating and cross-linking the composition comprising the fabricated component by exposing the coated component to high-energy ionizing radiation.
