SL products are silicone-impregnated, 100% fiberglass fabrics. They are formulated to provide a fabric that offers high-temperature protection while remaining flexible and offering a high degree of abrasion resistance. SL fabrics are specifically designed for use as a jacketing material for high-temperature removable insulation pads and as a welding cloth. SCUFFCOAT was designed to offer increased protection for spray shields used on high-temperature, high-pressure piping systems and mechanical joints.
