The low tack protection film has a certain viscosity during the process of use, and the different appearance of the product is suitable for a different adhesive maintenance film such as an optical protective film. In the purchase, it is necessary to first understand the classification of the protective film adhesion level, the screen The maintenance film can be subdivided according to the degree of viscosity of the adhesive: ultra-low-viscosity maintenance film, low-viscosity maintenance film, medium-low-viscosity maintenance film, medium-viscosity maintenance film, high-viscosity maintenance film, and ultra-high-viscosity maintenance film.
1. The ultra-low-viscosity maintenance film is originally one of the weakest types of adhesives compared with other maintenance films, and the adhesion is 0.9 N/cm. Most commonly used in light guide plates, instrumentation, screen display, glass cover, plastic sheet and other goods. Convenient and easy to stick and easy to tear, the residual glue on the item will not stay. The low-viscosity maintenance film has better adhesion and better adsorption.
2. The adhesion of the medium-low-viscosity maintenance film is relatively stable, the adsorption is good, the detachment function is good, and there is no residual glue scene, and its adhesive force is 1.2 N/cm. Applicable to furniture light guide plate, stainless steel plate, ceramic tile, marble, artificial stone, etc. Its medium viscosity maintenance film use: Suitable for fine grain sanding board and usually difficult to stick data maintenance.
3. High-viscosity maintenance film use: The adhesive force is more stable, the adhesion is better, the re-shedding function is outstanding, there is no residual glue scene, and the high-viscosity maintenance film adhesion is 1.5N/cm. Suitable for hard-to-stick materials, fine-grained sanding board, aluminum-plastic board, etc. The super-high-viscosity maintenance film has a adhesion of 1.9N/cm. The adhesive force is extremely high, and the water-based acrylic is used as the pressure-sensitive adhesive. It is convenient to use, easy to stick and easy to tear, and has no residual glue scene. It is suitable for viscous materials such as rough-patterned aluminum plates.
