∎Product Description

●SI8125A/B is used in potting protection of varied components. It can vulcanize to deep layer. The two components have a good fluidity after mixing. The operation time can be adjusted with the proportion of hardener part B. It can bond well with most materials without using any primer. It can be used to fix the accessories to resist water, dust and leakage of electricity.

.

∎Typical Applications

●Used for Automotive electronics, modules like Power control modules, Solar modules, Junction box, LED spotlight, Wall washer light, Strip lights, LED fluorescent lamp, etc.

 

∎Key Features

●Two-component high transparency liquid silicone rubber, condensation dealcoholization type

●Low viscosity, easy to process and operate

●Low hardening condensation, no corrosion and stressless

●Excellent electric insulativity and stability in high temperature 

●Excellent bonding ability, good water-proof and moisture-proof property

∎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.

It’s non-dangerous goods, can be transported as normal chemicals, CAUTION leakage during transport.

 

.∎Directions for Use

Mix Part A and Part B by 100:10 mass ratio, after evenly mixed, pouring directly into the components or modules as per requirements. It’s recommended to slowly pour along the walls of the implements, so as to reduce the bubbles happens.

Still the potted component to let out the bubbles. Vacuum defoaming process of the mixture before potting can improve the performance.

 

∎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.
