About spotLESS Materials

Surface fouling is a costly challenge across industries, impacting medical consumables, diagnostic devices, and automotive components. Contamination from substances like mud, ice, and sludge can compromise performance and lead to frequent cleaning, repairs, and replacements. Our PFAS-free coating, which we first launched as a consumer product, has quickly expanded into industrial partnerships. It dramatically reduces contamination on critical surfaces such as glass, metal, ceramic, and now plastics too. Whether for medical devices or automotive components, our coating protects against surface fouling Currently our coatings work best on glass, metal, and ceramic surfaces.
