Solution for high viscosity of PE protective film

An PE protective film adhesive industry, PE protective film with acrylic pressure-sensitive adhesive coating production (silica gel for most PET protective film), protective film adhesive force depends on the ratio of raw rubber and glue, pressure sensitive adhesive protective film coated high viscosity appeared in addition to the protection of membrane adhesion high in the application process also, with a coating and storage temperature and pressure have a direct relationship.

PE protective film viscosity mainly depends on the thickness of the silica gel decided, when Dongli brand mobile phone screen protective film before, have encountered such problems as high viscosity represents the thickness, when the heat will be posted on the silica gel thermal expansion and contraction, when the mobile phone screen will be like sweating, referred to as the glue industry so, the viscosity is not too high, otherwise in use will find it difficult to tear off the protective film when Dongli brand screen protective film product design after a number of tests, and finally found the suitable data and combined with the thickness of the protective film thickness to ensure the evenness of the products, high scratch resistant, high clear objective.

As everyone knows, only on the pressure sensitive adhesive, you can adjust the paste or paste after the storage pressure; if the protective film itself high viscosity, can be considered to be cooler weather after use (use 20 degrees below can obviously feel adhesion relative decline).
