Maxtech SI8706 Two Component Dielectric Silicone Rubber Sealant Gel for Electrical Junction Box
∎Product Description
SI8706 is two-component transparent self-healing silicone gel, when cured it will become elastomer with buffer and self-recovery property. Used to isolate moisture and other noxious pollutant from contacting the circuit board, also used as dielectric of high voltage. The other usage is stress relief for protecting circuit and interconnect devices from high temperature and mechanical stress.
∎Key Features
-
1:1 addition type, good adhesive strength and self-healing
-
High elongation, excellent flexibility for mechanical stress relieving
-
Low oil penetration after cured, good anti-poisoning property
-
Good dielectric in high temperature for high voltage protection
-
Excellent aging resistance and weatherability
-
Excellent waterproof, corrosion prevention, moisture-proof and chemical media resistance

How to use ?
-
Mix Part A and Part B by 1:1 mass ratio, after evenly mixed, pouring directly into the components or modules as per requirements.
-
Still the potted component to let out the bubbles. It can be heat cured, about 10mins in 80°C. It needs about 30~60mins cured under room temperature.
-
Vacuum defoaming can improve the performance of cured product.
-
Seal the remaining products tightly after use.
-
Low temperature will slow the curing speed; heat curing is recommended.
-
It's hard for SI8706 to cure if contact with sulfur, amine or Sn
