Maxtech SI8350 Two Component Dielectric Soft Silicone Gel Elastomer for Electrical Junction Box
∎Product Description
SI8350 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 another noxious pollutant from contacting the circuit board, also used as a dielectric of high voltage. The other usage is a stress relief for protecting the 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.
-
Cure condition: 25°C/30mins, 80°C/10mins
-
-
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 SI8350 to cure if contact with sulfur, amine or Sn
