SI8715 Dielectric Gels For Potting And Protecting PCB & Power Modules
∎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 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 components from high temperature and mechanical stress.
∎Typical Applications
●Used for encapsulation of various modules, semi-conductor, IGBT, automotive ECU module, IC chip, weighing sensor, waterproof connector.
Electrical insulation and moisture protection for low-voltage applications, particularly suitable for insulating cables and wires in junction boxes.
● FIll, Encapsilation, potting : filling junction boxes. Encapsulating or potting electrical components or enclosure. Encapsulating electronic boards and components, Water meter.
Industrial: Electronic contracting Telecommunications manufacturing Robotics Marines and Aquatics DIY Electronics.

∎Transport &Storage
● When stored at or below 25°C in the original unopened containers, this product has a usable life of 12 months from the date of production. Sampling test is necessary for products which exceed shelf life before taking use.
It’s non-dangerous goods, can be transported as normal chemicals, CAUTION leakage during transport.
.∎Directions for 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
∎Attention of operation
●Keep away from Children
●Avoid contact with eyes and skin. If contact with your skin, scrub first with soap water or alcohol, then rinse with water. If contact with your eyes, rinse with plenty of water, and seek medical treatment immediately.
● It is forbidden to build on the surface of the wet substrate.
