Two Component Silicone Potting Adhesive SI8130 A/B
∎Product Description
∎Product Description
SI8130 A/B is suitable for potting protection of various components. It can be deep-cured, and the two components have good fluidity after mixing. The operating time can be adjusted according to the temperature of the curing agent. There is no need to use other primers before use, it has a good bonding effect to most materials, and is suitable for fixing accessories, waterproofing, dust proofing and preventing leakage.
∎Typical Applications
●Automotive electronics, modules
●Various sensors
●Power control module
● solar junction box
●LED to shoot the light, wall wash lights, strip lights, LED fluorescent lamp
∎Key Features
●Two-component liquid silicone rubber, condensation and dealcoholization type
●Low viscosity, easy processing, strong operability
●Low hardening shrinkage, no corrosion and stress
●Excellent high-temperature electrical insulation and stability
●Excellent adhesion
●Good waterproof and moisture resistance
●Flame retardan
∎Directions for Use
Mixing uniformity in the packing before using, as there’s part of filler sedimentation happens during storage.
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. If possible, customers can vacuum and degas the mixed glue before potting. It can be cured directly at room temperature, usually within 1-6hr, the glue layer is elastic and can be turned over or handled.
- Vacuum defoaming can improve the performance of cured product.
- Seal the remaining products tightly after use.
- Low temperature will slow the curing speed, overheating will lead to curing speed too fast. Keep the constant temperature in workshop is recommended.
- It's hard for SI8130 to cure if contact with sulfur, amine, organotin.
∎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.
