Maxtech SI8709 Two Component Dielectric Insulation Liquid Silicone Gel
 
∎Typical Applications
●Used for encapsulation of various modules, semi-conductor, IGBT, automotive ECU module, IC chip, weighing sensor, waterproof connector.
 
∎Product Description
SI8709 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
.
∎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
 
∎Packing Specification
●Part A—10 KG/Bucket
●Part B—10 KG/ Bucket.
 
∎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 cured by heat, about 30mins in 80°C. It needs about 6 hours cured under room temperature.
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 SI8709 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.
