Silicone pressure sensitive adhesive for hot bending film
Let's first understand what hot bending film is-hot bending film, as the name implies, is a protective film processed by hot bending process. There are two common types of PET plastic film and tempered glass protective film in the market. Today, Kanglibang will talk about these two kinds of silicone pressure-sensitive adhesives for hot bending film.
PET hot bending film
Coat the corona PET film with Kanglibang KL-2610/2620 series silicone pressure-sensitive adhesive, and control the thickness of the wet glue through the comma, micro-gravure coating or slit coating process, and then heat and bake it in a tunnel furnace Cooled and covered with release film. According to the required size, the flat PET protective film is die-cut, and then processed by the hot bending process to form a 3D PET hot bending film with curvature.
Tempered glass hot bending film
It is divided into two processes: first hot bending and then gluing and first gluing and hot bending. In the former, the 2D flat glass is first coated with AB glue, there is no acrylic glue on the A side, and the B is Kanglibang KL-9302 silicone pressure-sensitive adhesive, and then formed in the hot bending machine; the latter is first made to make the 2D tempered glass through the hot bending process , And then apply AB tape.
Our special silicone pressure-sensitive adhesive for thermo-bending film is mainly used for AF screens, and the AF screen with a water drop angle of 115°. The peeling force can reach more than 60g. There are many models to choose from, and the hardness of the rubber surface is adjustable. Welcome to consult and exchange: 400-611-9269
