MDGEL 6708 waterproof Transparent silicone potting gel
- 1:1 additive molding, strong adhesion, self-healing
- High elongation; Excellent flexibility, eliminating mechanical stress
- Very low oil permeability after curing, excellent resistance to toxicity
- High temperature electrical insulation is excellent, to provide protection against high pressure
- Excellent aging resistance and weather resistance
- Excellent waterproof, anticorrosive, moisture-proof, chemical medium resistance
- It can be used in semiconductor modules, sensors, etc
MDGEL 6708 is a transparent two-component self-healing silicone gel. After curing, it forms a special soft material with buffer and automatic recovery. It is designed to insulate circuit boards from moisture and other harmful contaminants and to provide insulation against high voltages. Another use is to provide stress relief to protect circuits and interconnectors from high temperature and mechanical stress.

Operation Use craft
- The A and B components are weighed at a ratio of 1:1, mixed evenly, and injected directly into the components (or modules) that need to be potting and protected.
- The potting components can be put to rest and cured at temperature (about 30 minutes under the condition of 80 ° C), or cured directly at room temperature, which takes about 8-10 hours.
