Optional paragraph: Two points need to be considered: the microporosity of the material to be adhered and the surface adhesive of the protective film.
There are many types of protective films, and their surface adhesives are also different. There are many types of protective films, so the performance and strength of various brands of protective films are different. Therefore, when purchasing protective films, the following factors need to be considered:
The microporosity of the object to be adhered: Due to the adhesive effect of the protective film, the moisture of the adhesive on the surface of the protective film infiltrates into the adhesive and quickly dries, making the protective film a part of the adhesive. Therefore, the microporosity of the surface of the object to be adhered is very important for the selection of the protective film. If there are many micropores and high moisture absorption, a protective film that quickly solidifies with the adhesive should be used. Otherwise, a protective film with slower coagulation speed or a protective film containing more adhesive should be used.
Adhesive on the surface of protective film: The protective film is coated with adhesive on the bottom tape in the manufacturer, and usually needs to be fully dried before being sorted into rolls. If the adhesive protective film is too wet, it will stick tightly together and be difficult to open during use, and some cannot be used at all.
