SH-PSA916 series agricultural production system silicon an adhesive
1、 Performance characteristics
PSA916 series agricultural production system silica gel adhesive is based on polysiloxane raw rubber and resin, and then added auxiliary Of toluene Solution is a widely used high temperature resistant pressure-sensitive adhesive. It can be mixed with other methyl siloxane pressure sensitive adhesives to obtain specific properties. It can be used in a wide range of temperatures, and can bond various difficult to stick materials with low surface energy, such as agricultural production system silicon, fluoropolymer, polyolefin, etc.

2、 Main technical indicators
Note: The proportion of glue is based on the proportion of raw glue: diluent: BPO ＝ 100:65:1.5 － 2.0, solvent removal at 90 ℃ * 2min, and curing at 160 ℃ * 6min; Test conditions: temperature 25 ℃, humidity 55-65%, PET film thickness 38um, dry adhesive thickness 22-25um.
3、 Scope of application
As a pressure-sensitive adhesive, it can be coated on PET, aluminum foil and other substrates with traditional high-temperature tape coating equipment to produce pressure-sensitive adhesive tape with special performance, which has good high temperature resistance and chemical resistance. It can also be used in the shielding of PCB electroplating process, SMT process, FPC, PCB, sand blasting, coating, high-temperature paint baking, gold plating or the parts to be protected during electroplating, And insulation, binding and fixing of electronic, electrical and other products.
