Vehicle-grade transparent self-healing encapsulated silicone gel

JOMS  5606 It is a transparent two-component  self-healing silicone gel, which becomes a special soft  material with buffer and automatic recovery after curing.Used to isolate moisture and other harmful contaminants  from  contacting  the  circuit  board,  and provide an insulator for high voltage. Another use is to provide stress relief to protect circuits and interconnectors from high temperatures and mechanical stress.

1:1 addition molding, strong viscosity High elongation; excellent flexibility, eliminate

Suitable for potting of various modules and power supplies

Operation process

Weigh A and B components in the ratio of 1:1, mix evenly, and directly inject into the components (or modules) to be potted and protected.

The potted components can be left to stand and can be heated and cured (at 80℃ , it takes about 60 minutes), or they can be cured directly at room temperature, which takes about 24 hours .

Precautions

Vacuum defoaming of AB components after mixing can improve the performance of hardened products

Components A and B should be sealed and stored after being taken

Too low temperature will lead to slow curing speed, it is recommended to heat and cure

JOMS 5606 is difficult to harden in contact with sulfur, amine and tin materials .
