Features & Benefits
1. Two component, room temperature curing.
2. After curing, it forms a non porous, low-permeability silicone rubber layer that prevents the penetration of moisture, salt spray, and oily media.
3. Excellent electrical insulation performance.
4. It has a wide temperature range, maintaining its elasticity and mechanical properties in a broad temperature range of-50°C to +200°C.
5. It is UV-resistant, ozone-resistant, and resistant to high and low temperature cycling. Its performance remains essentially unchanged after 1000 hours of aging at 85°C/85% RH.
6. Low shrinkage and low stress, there is virtually no volume shrinkage during the curing process, preventing cracks or delamination caused by stress.
Applications
1. Waterproof, dustproof, and insulating packaging for ICs, power semiconductors, sensors, LEDs, wireless chargers, automotive ECUs, transformers, etc.
2. Waterproof, dustproof, and vibration-resistant packaging for headlights, instrument panels, and in-car control units.
3. Waterproofing and sealing of concrete, metal, and glass joints; roof waterproofing; bridge corrosion protection.
4. Waterproofing for photovoltaic junction boxes, internal waterproofing for wind turbine nacelles, and moisture-proof sealing for energy storage systems.
5. Long-term immersion protection for water pumps and submersible connectors.

construction method
Clean the substrate surface to remove oil and dust. If necessary, use isopropanol or a specialized primer to ensure the surface is dry. Accurately weigh components A and B according to the weight or volume ratio (1:1). Slowly add component B to component A, and mix using a low-speed high-speed disperser or by hand for 2-3 minutes. The container capacity should be approximately three times the volume of the adhesive. Immediately after mixing, perform vacuum degassing for 5-10 minutes to remove any trapped air bubbles. In a dust-free environment, quickly inject the adhesive into the cavity to be encapsulated. This can be done using a manual dispensing gun, an automatic dispensing machine, or a vacuum potting machine, avoiding the formation of secondary air bubbles.
