Description
SUITIT HH-5633 is a two-component room-temperature vulcanized silicone gel, specially developed for potting and encapsulation of electronic devices requiring high flame retardancy. It adopts a user-friendly 1:1 volume mixing ratio with good fluidity for filling complex structures; it cures without heat generation and low shrinkage, forming elastic protective layers after curing.
Features
- Convenient 1:1 volume mixing ratio, compatible with automatic dispensing equipment and manual operation
- Superior flowability to easily penetrate intricate internal structures
- Heating treatment can significantly speed up curing progress
- Supports deep-layer curing or post-assembly in-situ curing, non-exothermic with low shrinkage rate
- Excellent elasticity after curing, free of brittleness and powder shedding
- Wide working temperature range: -50 ~ 200℃
- Flame retardant performance reaches UL94 V-0 grade
