Insulating dielectric gel for enclosures waterproofing SI2709A/B
SI2709 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.
Usage and Key Features of Silicone Gel
Used for encapsulation of various modules, semi-conductor, IGBT, automotive ECU module, IC chip, weighing sensor, waterproof connector.
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 age resistance and weather resistance 6. Excellent waterproof, corrosion prevention, moisture proof and chemical media resistance

The curing time and hardness can be adjustable, if this product can not meet your requirements, please contact with us, we will recommend the most suitable products to you.
Direction for 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. The operation time is short, can cure in a short time, the
fixture time is about 30 to 40 minutes, potting equipment is recommended for application.
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 SI2707 to cure if contact with sulfur, amine or Sn
