Abstract
A process for the production by a moulding process of a micro-cellular or non-cellular elastomeric polyurethane skin layer or, more generally, to a process for the production of a composite comprising a first layer shaped part, which is made by a moulding process from a polyurethane reaction mixture, and a second layer shaped part which is adhered to the first part to form the composite. In order to avoid the use of release agents on the back side of the first layer shaped part, and thus the negative effect on the adhesion of the second layer shaped part, and the penetration of reaction mixture on this back side between the slides () of the mould, the mould surface () is covered on the back side of the moulding with a removable flexible covering (), with a removable rigid pre-shaped covering or with a permanent non-stick coating layer.
