Maxtech SI8715 Two Component Dielectric Insulation Liquid Silicone Gel
∎Product Description
SI8715 is two-component transparent self-healing silicone gel, after cured it will become quite elastic material with buffer and self-recovery. 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 circuits and components from high temperatures 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 30mins in 80°C. It needs about 4-5hours cured under room temperature. Require 24 hours to achieve surface without obvious oil layer.
-
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 SI8715 to cure if contact with sulfur, amine or Sn
