Flexible Potting Compound 1:1 Silicone Potting Material For PCB EV Battery Power Module Electronic Potting Gel

Product Overview for 1:1 flexible potting compound:

1:1 silicone potting compound is a two-component liquid silicone rubber. The "1:1" in its name refers to the requirement that component A (base compound/main agent) and component B (curing agent/catalyst) must be precisely mixed in a 1:1 volume or weight ratio before use. After thorough mixing, the material undergoes a chemical reaction (usually an addition reaction, also known as platinum curing), solidifying from a liquid state into a soft elastomer.

It is a special silicone material specifically designed for potting, sealing, and protecting electronic components and modules.

FAQ for 1:1 flexible potting compound:

Q: What does "excellent deep cure" mean? A: It means the compound cures evenly throughout thick layers or deep cavities, preventing a tacky, uncured center and ensuring consistent protection.

Q: What is the benefit of low shrinkage? A: It avoids introducing internal stress on precision components and solder joints, preventing damage or performance drift.

Q: Is a RoHS certificate available? A: Yes, a compliance test report can be provided upon request.

Q: Is it sensitive to moisture? A: It is slightly moisture-sensitive before cure. Reseal containers and store in a cool, dry place after use.

Q: Can it be used for sensors with plastic housings? A: Yes, its low stress and good elasticity make it ideal for protecting sensitive elements and providing a seal.
