SI350 Fast Curing Waterproof Silicone Gel Cable Junction Box Potting Sealant
SI350 High Quality Fast Curing Waterproof Silicone Gel Cable Junction Box Potting Sealant
Product description
GEL350 is a transparent two-component robust dielectric gel that cures to form a soft cushioned flexible material. 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.
l 1:1 addition molding for easy operation
l Excellent flexibility, eliminate mechanical stress
l Very low oil permeability after curing, excellent resistance to toxicity
l High temperature electrical insulation is excellent, to provide protection against high pressure
l Excellent aging resistance and weather resistance
l Excellent waterproof, anticorrosive, moisture-proof, chemical medium resistance
l It is suitable for cable connection box, waterproof junction box and underwater instrument
l Widely used in power electronics, ignition module potting

Operation and use process
l 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. It is best to slowly inject along one side of the wall, which can reduce the generation of bubbles.
l The potting element is left to stand and let it bubble itself. After the bubble basically
Precautions
l Vacuum defoaming of AB components after mixing can improve the performance of hardened products
l A and B components should be sealed and stored after use
disappears, it can be heated and cured (under the condition of 80℃, about 10 minutes). It can also be cured directly at room temperature, about 30mins.
l Please consult the Marketing Department of our company for the potting equipment that needs quantitative gluing.
l Too low temperature will lead to slow curing speed, it is recommended to heat curing
l MDGEL 350will be difficult to harden in contact with materials containing sulfur, amines, rosin, organometre-metal salts, and tin
