New urethane foam should be protected by a high quality polyurethane coating to provide a waterproof, fire-retardant, solar-reflective and hail-resistant finish. Polaroof RAC provides this, with approvals from both Underwriters Laboratories and Factory Mutual, so that the best quality standards are maintained. Additional chemical resistance around stacks, vents, and grease traps is provided by using OZ Catalyst to convert Polaroof RAC to Polaroof RAC-OZ oxazolidone coating.
