Abstract: various adhesives can be made by adding a specific amount of a certain material to artificial rubber. Determining how many kinds of materials are needed in adhesive is the goal of adhesive design technology. At present, Kaimo technology mainly has the following types of protective film adhesive materials:

A variety of adhesives can be made by adding a specific amount of a material to artificial rubber. Determining how many kinds of materials are needed in adhesive is the goal of adhesive design technology.

At present, there are mainly the following types of protective film adhesive materials for Kai film technology:

Types of adhesives

Rubber, acrylic and siloxane adhesives are used according to the required application, and each material is designed to take advantage of the different characteristics of rubber.

Rubber adhesive

Natural rubber itself only has a certain degree of adhesion, and some tackifier is usually added. This allows it to adhere to various adhesives and is usually used in packaging tapes.

Acrylic adhesive

Acrylic polymers with various functions can be synthesized by selecting acrylic monomers and copolymerization, so that they can be used as adhesives. Because of its outstanding performance in transparency and weather resistance, heat resistance and solvent resistance, it is widely used in LCD panels, mobile phones and automotive applications.

silicone adhesive 

Silicone rubber is excellent in heat resistance, polarity and extreme temperature, and can be used at various temperatures. Because it only has low adhesion, silicone resin is used as tackifier. By changing the structural ratio of silicone rubber and silicone resin, the required bonding properties can be obtained. It is also crosslinked with crosslinking agents such as benzoyl peroxide to improve heat resistance.

Polyurethane adhesive 

This type of adhesive is used in applications such as protective films and fluff removers because of its excellent removability.
