Brief description of embodiments of a technical a coating polyurethane conferring a touch sensation improved

摘要

Process of producing a molded part comprising at least a substrate (2) and a polyurethane coating (3), comprises forming homogeneous layer of polyurethane gel (9) by applying in a bottom of the mold and crosslinking of a polyurethane precursor composition, forming a substrate by applying at least a thermosetting resin (10) on a homogeneous layer of polyurethane gel followed by crosslinking of the thermosetting resin and demolding of the molded part, where the crosslinking of the precursor composition is partial for maintaining isocyanate functions before applying the thermosetting resin. Process of producing a molded part comprising at least a substrate (2) and a polyurethane coating (3), comprises forming homogeneous layer of polyurethane gel (9) by applying in a bottom of the mold and crosslinking of a polyurethane precursor composition, forming a substrate by applying at least a thermosetting resin (10) on a homogeneous layer of polyurethane gel followed by crosslinking of the thermosetting resin and demolding of the molded part, where the: crosslinking of the precursor composition is partial for maintaining isocyanate functions before applying the thermosetting resin; and thermosetting resin is epoxy resin and unsaturated polyester. An independent claim is included for a molded part obtained by the above process, comprising the substrate formed of crosslinked thermosetting resin, where the substrate is at least partially covered with a polyurethane coating providing an improved feel.
