Product Advantages
High-Performance Elastomer: Forms a high-elasticity, high-strength protective layer after curing.
Low Viscosity: Suitable for deep-section potting, ensuring even distribution.
No By-Products: No heat or by-products are emitted during curing, ensuring component safety.
Flame Retardant: Passes UL-94 flame retardancy tests, ensuring safety in high-temperature environments.
Eco-Friendly Certification: Complies with RoHS standards, non-polluting.
Applications
Potting and sealing of power modules, circuit boards, and high-voltage transformers.
Protection and thermal management for battery packs and fast-charging adapters.
Moisture-proof and waterproof protection for LED outdoor drive power supplies.
Other electronic components requiring vibration, water, and thermal protection.
Application Method
1.Mix components A and B in a 1:1 ratio, stir thoroughly, and then proceed with potting.
2.Ensure the surface of the components is clean before potting. For large products, pot in stages.
3.For automated production lines, vacuum components A and B separately to ensure accurate mixing ratio.
