This NM-5020 Power Supply Potting Silicone Adhesive produced by Nuomi silicone Adhesive supplier is a two-component potting glue. Components A and B are used together in a ratio of 1:1 (weight ratio). This Power Supply Potting Silicone Adhesive is packaged in 10KG/barrel, 20KG/barrel, and 25KG/barrel.
1. Excellent heat dissipation performance, thermal conductivity ≤0.8W/m・k, can efficiently guide the internal heat dissipation of the power supply, greatly improve product reliability, and extend service life. 2. Possess excellent flame retardant properties. 3. Strong bonding force, excellent bonding effect for all kinds of material products. There are no bubbles inside the cured product, which can achieve the best thermal conductivity and protection effect, excellent waterproof performance, and protection level up to IP67. 4.The A and B two-component curing system is adopted to ensure that the colloid does not shrink during the curing process, and rapid deep curing can be achieved without contact with air.
