Because different humidity and ambient temperature do have a greater impact on the viscosity of the protective film, because the adhesives of the protective film are mainly solvent-based adhesives, the presence of moisture will inevitably be affected by the environment. Viscosity fluctuations.
To put it simply, when the weather is cold and the air is dry, the intermolecular vitality of the adhesive decreases, and the viscosity decreases. In the warm and humid spring, the viscosity will increase a little, especially in the hot summer, the adhesive viscosity will be higher. If it is a particularly humid environment, moisture may penetrate into the glue layer (there are many adhesives that are water-soluble glues), and the viscosity will also change differently.
Therefore, the use of protective film, especially the large-scale film in the industry, before the official production, it is recommended that you test several times to eliminate these external unfavorable factors completely, so that the film protection process can be completed better and more stably. The factory can It also saves manpower and material costs, and reduces product losses due to technical errors in filming.http://pe-protectionfilm.com/
