Product Description

China Superior Elasticity Silicone Gel for IGBT PCB Potting

LEED-INK silicone gel compound is a liquid-forming silica gel which could be cured either under room temperature or through heating. It has features of excellent moisture&water proof, weather proof, ozone&radiation resistance. It could be long term used under -40℃-200℃, with good electrical property and chemical stability. Before vulcanization, it is colorless transparent liquid form and separately packaged with component A and component B. It is with low viscosity that easy of potting. After vulcanization, it is transparent viscoelastic body with low modulus, high elongation & adhesion, strong self-healing capability and tearing resistance.

Benefits of Silicone Gel for IGBT PCB Potting

1. Low viscosity
2. Excellent adhesivity with various materials such as ceramics, metal, plastic, etc.
3. Strong self-healing capability, high tearing resistance, excellent moisture resistance

1) Component A and component B should use special tools separately. Do not use the tools in mixture.
2) Separately stir component A and component B fully and evenly before using.
3) Mix according to A:B=1:1, and stir it over 15min to ensure the mixing uniformity of component A and B.
4) After mixing, deaerate the paste in vacuum equipment with 10min before potting. To ensure the potting quality, it is recommended to deaerate again after potting.
5) Please finish 3) and 4) within operating time.
6) Curing could be done by 90℃/1.2h, or 24h in room temperature.
