What glue is used to test the high temperature resistance of PET tape and protective film?

The PET tape and protective film tested in the Eighth Five-Year Plan are silicone pressure-sensitive adhesive, commonly known as silicone adhesive, which is generally made of silicone adhesive, liquid silicone, anchoring agent and pressure-sensitive adhesive according to a certain formula. The "Double Eighth Five-Year Plan" high-temperature test refers to the high-temperature and high-humidity test at 85℃ and 85% humidity for 4-24 hours. This kind is mostly used for product inspection after coated with PET mobile phone protective film. KL-26 10 is the main material, KL-298 is the anchoring agent, and KL-7657 is the high-viscosity silicone pressure-sensitive adhesive, which is vulcanized and molded under the catalysis of PT-4000 platinum water. Generally, comma scraper coater is used for production. Generally divided into dispensing, gluing, baking, winding, die cutting and other processes.
