PET-type optical film coating formulation technology-polyurethane coating Source: protective film factory direct sales Release time: 2019-06-17 Click: 1630 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 in the polyurethane coating molecule, it 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. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 10 years of experience. It can produce PET film with various functions, such as: sub-(matte) PET film, flame-retardant (fireproof) PET film, inkjet printing film , Antistatic PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, etc. Interested parties welcome to inquire!
