Excerpt: the need to consider the microporosity and surface protective film adhesive to paste the two.
There are many kinds of protective film, and the surface of the adhesive, the protective film protective film protective film, so the performance and strength of various brands are different, so we need to consider the following factors when purchasing protective film:
Microporous to adhensive: because the adhesive function of the protective film is the occurrence of lies in the surface of the protective film adhesive protective film adhesive after infiltration of moisture in the pasted object quickly dry and become a part of the protective film adhesive material, so the choice of adhesive material on the surface of the microporous membrane to protect the very an important, if more goods for microporous moisture stress, we must adopt protective film adhesive quickly, otherwise the protection film with condensation slower or protective film containing more adhesive.
The surface of the protective film adhesive protective film at the manufacturer with coated adhesive on the bottom, usually to fully dry after finishing rolls, if sticky protective film protective film itself is too wet will stick together, use is difficult to open, some did not.
