PET optical film coating formulation technology--polyurethane coating-film supplier
Diffusion film can be prepared by coating a layer of resin coating on PET film and other substrates. The coating uses polyurethane resin, and one or more organic or inorganic particles with a single particle size distribution are added to it as diffusing particles. The particle size of the diffusing particles is 1-50μm to improve the dispersion effect. In addition to a considerable number of polyurethane bonds, the polyurethane coating molecule also contains urea bonds, ether bonds, ester bonds, and allophanate bonds. The cured coating film has good wear resistance and corrosion resistance. It is a kind of coating material with excellent performance and wide application. Focus, lower water absorption, better thermal stability and acid and alkali resistance.
