Note: The proportion of glue is based on original glue: diluent: BPO = 100:65:1.5-2.0. After solvent removal at 90℃*2min, curing at 160℃*6min; test conditions: temperature 25℃, humidity 55- 65%, PET film thickness is 38um, dry glue thickness is 22-25um.
Excellent Characteristics
It can be mixed with other silicone pressure-sensitive adhesives to obtain specific properties. It can be used in a wide temperature range and can bond a variety of difficult-to-bond materials with low surface energy, such as silicone, fluoropolymers, polyolefins, etc.
Main Use
As a pressure-sensitive adhesive, traditional high-temperature tape coating equipment can be used to coat PET, aluminum foil and other substrates to produce pressure-sensitive adhesive tapes with special properties. It has good high temperature resistance and chemical resistance, and can also be used for printing. Shielding during the circuit board electroplating process, SMT process, FPC, PCB board, sandblasting, painting, high temperature baking, gold plating or the parts that need to be protected during the electroplating process, as well as insulation wrapping and fixing of electronic, electrical and other products.
