SI22225 Two-component Transparent silicone potting compound
?Product Description
SI2225A/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.
?Key Features
1. Two-component high transparency liquid silicone rubber, condensation dealcoholization type
2. Low viscosity, easy to process and operate
3. Low hardening condensation, no corrosion and stressless
4. Excellent electric insulativity and stability in high temperature
5. Excellent bonding ability, good water-proof and moisture-proof property
?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.

?Directions for Use
1. 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.
2. Still the potted component to let out the bubbles. Vacuum defoaming process of the mixture before potting can improve the performance.
