Why is the glue around the film on the crystal steel door always open?

The film will deglue over time. This is due to the reaction between the benzene-containing glue and the glass glue and the nature of the glue itself.

Causes for problems with crystal steel door films:

1. There are bubbles, wrinkles, and odors when applying the film, which is caused by the base film and the glue;

2. The black spots and impurities on the surface of the film are leftover from the iron frame assembly line on the gluing production line.

Method:

For small bubbles, you can use a needle to pierce them and then glue them back together. For large bubbles, use a razor blade to cut them, then glue them and flatten them carefully. There will still be no problem in use. .

As for the degumming, it needs to be reattached.
