A good protective film of tempered glass depends on four aspects: Tempered, oil Coating, AB glue and exhaust effect.
Firstly , to observing whether the product appearance is clean and glass surface with fog points or not.
Secondly, after tempered for 3 hours together with premium raw materials and itself did not with internal injuries , meanwhile available to bending and not easy broken and after the broken pieces of dense into line and not to drop , it is up to standard. In fact, based on the material properties of the glass, to tempered 3 hours is enough, actually for four hours and even for a long time the effects are the same. It is easy to causes the glass internal injuries after a long time tempered and starting to backfire.
Next, the standard of our products for oil coating is makes the drop angle to be 105-110 degree, while drops of water on the surface of the glass.
Finally, except the hot bending curved glass, for other glass protectors when installation, the AB glue should be exhausted at one time, leaving without traces.
