20220186069 · 2022-06-16 ·

A method for producing a coating on a surface of a component part or a device, the method comprises obtaining a two component polyurethane system having a Component A and a Component B, Component A comprises a polyol and Component B comprises an isocyanate. Either Component A or Component B or both components comprise a filler. The method includes mixing Components A and B, to form a mixture comprising the polyol, the isocyanate, and the filler. The method includes applying the mixture to a surface of a component part or a device to form a coating from the mixture; and allowing the applied coating to cure. The steps of applying the coating and allowing the applied coating to cure are performed at an ambient temperature, and the viscosity of the mixture immediately after the mixing step is from 10 Pas to 500 Pas at 23° C.
