Two Component Soft Silicone Gel Elastomer 350
∎Product Description
Gel 350 A & B is a two component silicone elastomer that crosslinks at room temperature by polyaddition reaction.The pueolymerisation can be accelerated by heat ( max. 150℃ ).
The silicone components are delivered as two component low viscous liquids, which once mixed and cured,transforms into a transparent coloured,solid, elastic,self rebound and resistant material. Polymerisation occurs without formation of heat.
The cured gel is used in some medical applications with high strength, such as mattress, headrest, goggles, skin sticker.

∎Typical Applications
●Suitable for cable connection box, waterproof junction box, underwater instrument
● Widely used in power electronics, ignition module potting
∎Key Features
- 1:1 addition type, good adhesive strength and self-healing
- High elongation, excellent flexibility for mechanical stress relieving
- Low oil penetration after cured, good anti-poisoning property
- Good dielectric in high temperature for high voltage protection
- Excellent aging resistance and weatherability
- Excellent waterproof, corrosion prevention, moisture proof and chemical media resistance
∎Packing Specification
●Part A—10 KG/Bucket
●Part B—10 KG/ Bucket.
∎Transport &Storage
● When stored at or below 25°C in the original unopened containers, this product has a usable life of 12 months from the date of production. Sampling test is necessary for products which exceed shelf life before taking use.
It’s non-dangerous goods, can be transported as normal chemicals, CAUTION leakage during transport.
.∎Directions for Use
-
Mix the A and B components at a ratio of 1: 1, mixed evenly and directly inject into the component (or module) to be potting protected. Preferably smooth one side of the receptor wall is injected slowly to reduce the formation of bubbles.
- The pot-sealed component is left standing, allowing it to spontaneously bubble, After the bubbles are basically disappeared, it can be cured (at 80 ° C, it takes about 10 minutes).
3.It can also be solidified directly at room temperature conditions, and the transparent model is around 20MINS, the black model is about 60MINS.
∎Attention of operation
●Keep away from Children
●Avoid contact with eyes and skin. If contact with your skin, scrub first with soap water or alcohol, then rinse with water. If contact with your eyes, rinse with plenty of water, and seek medical treatment immediately.
● It is forbidden to build on the surface of the wet substrate.
