Silicone adhesive/protecting coating for Polyester/plastic film For some plastic film, please use our ST-8211 for primer
PSR-8211 In Led encapsulation, print circle board and LCD process, the surface needs correctly protection from heat and dust. Besides, in mobile phone , LCD monitor or plastic and metal surfaces, PSR-8211 act as protect and buffer layer between (-50) to 200℃ condition for long time operation.

Operation process :
weight : Take PSR-8211A and PRS-8211B by 1:1 (weight ratio).
Defoaming : place the mixture in vacuum vessel，kept vacuum lower than 100 mg Hg.
Filler : Be careful pouring silicone to the container, avoid Occur bubble
Harden : Heating 150℃X 2~3 min. then finished.
