Maxtech SI8760 Two Component Waterproof Liquid Silicone Gel Cable Junction Box Potting

Product Description

SI8760 is two-component transparent self-healing silicone gel, when cured it will become an 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. 1:1 addition type, good adhesive strength and self-healing 

  2. High elongation, excellent flexibility for mechanical stress relieving

  3. Low oil penetration after cured, good anti-poisoning property

  4. Good dielectric in high temperature for high voltage protection 

  5. Excellent aging resistance and weatherability 

  6. Excellent waterproof, corrosion prevention, moisture-proof and chemical media resistance

∎Typical Applications

Used for encapsulation of various modules, semi-conductor, IGBT, automotive ECU module, IC chip, weighing sensor, waterproof connector.

How to use ?
  1. Mix Part A and Part B by 1:1 mass ratio, after evenly mixed, pouring directly into the components or modules as per requirements.

  2. Still the potted component to let out the bubbles. It can be cured by heat, about 30mins in 80°C. The fixture time is about 4-5 hours when curing under room temperature. Require 24 hours to achieve surface without obvious oil layer.

  3. Vacuum defoaming can improve the performance of cured product.

  4. Seal the remaining products tightly after use.

  5. Low temperature will slow the curing speed; heat curing is recommended.

  6. It's hard for SI8760 to cure if contact with sulfur, amine or Sn
