Description of silicone adhesive sealant

SATOP®8703 deketoxime silicone adhesive sealant is a neutral silicone sealant that absorbs moisture in the air at room temperature, can’t heat. It has good adhesion sealing property to most materials, to protect electronic products under stringent conditions.

Elastomer of SATOP®8703 silicone adhesive sealant has the following characteristics:

  1. Easy to operate
  2. Resistant to moisture, dirt and other atmospheric components
  3. Reduce mechanical stress and tension caused by mechanical, thermal shock and vibration.
  4. Excellent electrical insulation, anti – corona
  5. Excellent outdoor aging, service life can reach 20 to 30 years
  6. Stable mechanical and electrical propertiesbetween 60 to 260 ℃
