1. Pretreatment: clean and dry raw materials to remove impurities and moisture.
2. Dissolution: the treated raw materials are added into the solvent, and then dissolved into liquid after being stirred and heated.
3. Coating: The dissolved liquid is coated on the surface of the substrate with a coating machine to form a uniform film.
4. Curing: The coating film is cured by heating to form a stable chemical structure.
5. Inspection: Conduct quality inspection on the cured film, including thickness, tensile strength, temperature resistance and other indicators.
6. Cutting and packaging: Cut and package the qualified film for easy storage and transportation.
