We provide the coating of all kinds of foams using polyurethane. The polyurethane layer allows materials to be used where they are exposed to liquids and lubricants, while maintaining their high flexibility. This flexibility can vary from 350 to 800%. The layer thickness varies from 0.00039 inches (10μm) for thin, highly flexible coatings, up to 0.0065 inch (250 μm) for solid coatings. Polyurethane spray is resistant to water, oils, detergents and fuel. The coating is harmless and has a long lifespan. It is available in any colour from the RAL palette.
