Product description of silicone elastomer

SATOP®8821 Flexible skin adhesive is a two component platinum catalyzed transparent silicone elastomer. After A, B component is mixed, it is cured to form a soft adhesive material that has a cushioning adhesive skin that can be removed. The adhesive has unique physical properties and suitable for adhesion and self-adhesive materials used in biomedical applications.The elastomer adhesive consists of platinum-catalyzed polydimethylsiloxane. Curing temperature range: at room temperature to 200 ℃, and no by-products.

  1. Solvent-free two-component system
  2. Transparent before and after curing
  3. platinum catalytic curing system
  4. No curing byproduct
  5. low viscositybefore curing, easy to processing
  6. Excellent softness, no stress
  7. Very low oil permeability after curing, excellent anti-toxicity
  8. Adhesive adhesion can be adjusted by adjusting the ratio of AB material
  9. Repeatable paste
  10. Can use polyethylene release film
  11. Through tests of physiological compatibility, toxiccells, skin irritation, etc.

Typical applications

  • Suitable for boding with skin, can be used for wound dressing, eliminating scar paste, eye sticker, Etc.
  • Can also be used to fill heads, lumbar cushions, etc.


Part A: 20kg/barrel; Part B: 20kg/barrel

Part A: 200kg/barrel; Part B: 200kg/barrel

Storage and transportation

  • 1 Part A and part B need to avoid light, heat, save after sealed. (Can be used as the non-dangerous goods transport and storage)
  • Shelf life : 1 years (25℃)
  • For a long period of time, there will be precipitation, which can be used after stirring. This phenomenon is not a quality problem.

How to use of  silicone elastomer

  • Weigh part A and part B by 1:1, mix well, after standing for 10mins, gently inject into the side of the wall to reduce the bubble formation.  
  • Put the encapsulated element in place for some time. After the bubble disappears, it can be heated and solidified (about 2-5 minutes at 120°C, depending on the thickness of the adhesive layer), or solidified directly at room temperature, which requires about 4hr-6hr.

Attention of operation of  silicone elastomer

  • It can be improve hardening performance if remove the bubblesafter mixing part A and part B.
  • Seal preservation after taking part A and part B
  • can lead to slow curing speed under the too low temperature and recommended workshop temperature.
  • SATOP®8821 is difficult to harden and contact with materials such as sulfur, amine, organic tin and unsaturated hydrocarbon plasticizer. Common substances have rosin, natural rubber, before use must be tested.
