Why does silica transfer occur in the silicone PET protective film? -Film supplier
The phenomenon of sticky transfer is collectively referred to as the residual sticky displacement of the surface in uneven coating and transportation. Quality problems in protective film production technology, substrate (PET) and raw materials (adhesive) are all likely to cause adhesion transfer of PET protective film glue. The adhesion transfer is divided into the following situations: 1. Cohesive failure: the adhesion of the profile surface and the substrate surface, the loss of the surface gloss of the protective film coating 2. The damage of the adhesive base: the surface of the profile has more glue residue, and the glue of the protective film The substrate can be seen on the surface 3. Transmission residue: A small amount of adhesive remains on the surface of the profile, and the protective film adhesive maintains a good gloss.
