Can glass silicone pressure sensitive adhesive resist fingerprint?

Silicone pressure-sensitive adhesive is a kind of organic silicon polymer as the main body of pressure-sensitive adhesive, because of its chemical structure high bond length, bond Angle, bonding energy, and low surface energy, low surface tension, low rotation required energy, etc, compared with traditional acrylic, rubber pressure-sensitive adhesive, it has excellent high and low-temperature resistance, in the harsh environment (-50 ~ 150 ℃) can be used for a long time.

Good wetting, spreading, and bonding properties for low surface energy materials such as fluorine and silicon; Excellent chemical resistance, insulation, and dielectric properties; With the rapid development of consumer electronics and handheld electronic devices, manufacturers have developed more and more touch screens, such as 2.5D screen, 3D screen, anti-fingerprint screen.

Among them, in order to make the screen smooth, scratch resistant, stain resistant, and other properties, the surface energy of the screen after anti-fingerprint coating treatment is very low, the traditional protective film on its peeling force is low and unstable, poor adhesion to the substrate, after peeling the screen surface silicon transfer and other deficiencies.

In view of the shortcomings of the above technology, a kind of silicone pressure-sensitive adhesive applied to anti-fingerprint glass is needed, which has high peeling force against the fingerprint screens and does not decay. The substrate has good anchoring properties, no degumming after 2h boiling, high cohesion strength, and no residual glue after high temperature and high humidity aging.

The preparation process is simple and easy to realize industrial production. At present, it can be prepared from the following raw materials: hydroxy-terminated polydimethylmethylvinyl raw gum of 30 ~ 70 copies; Hydroxyl MQ resin 5 ~ 70; Vinyl MQ resin 5 ~ 70 copies; 0.2 ~ 1 copies of benzoic acid; 0.2 ~ 1.0 doses of inhibitor; Solvent 60 ~ 120 parts; 3 ~ 3 copies of hydrogen silicone oil; 0.5 ~ 2 pieces of anchorage agent; Platinum catalyst 1.5 ~ 3 copies; The mass ratio of hydroxyl MQ silicone resin to vinyl MQ silicone resin is 1:0.1 ~ 10.
