Method of producing polyurethane surfaces

Abstract

A method of making a decorative polyurethane panel which replicates the look of a pre-selected material is provided. A full size model of the material is first created having the desired texture and appearance. A tooling is then constructed to contain the model. The model of the material is encased with a two part silicone rubber compound that fills said tooling. The newly formed silicone mold is then removed from the tooling. Polyurethane components are separately mixed. The polyurethane mixture is then dispensed into the mold. The filled mold is covered with a vent paper. The mold is then fed into a press and pressure is applied. The mold is removed from the press and the newly created panel is then removed from the mold and allowed to cure. An outer finish is then applied to the panel so that it resembles the decorative appearance of the material.
