High power LED high silica QK-5573A/B folding package

High power LED high silica QK-5573A/B folding package

Product features:

This product is a two-component high refractive silicone fluid sealant. Mainly for large power and small size package, suitable for small SMD package such as 3014, 3528, 5050 series, with high light transmittance of high refractive index and high hardness. The electrical properties, breathable performance,the metal (copper, silver, aluminum) and other metal materials and PPAexcellent adhesion, and excellent thermal stability, resistance to high temperature of 250 ℃ can be a long time. Can be used for a long time at the temperature of -60~+220 ℃. And has excellent thermal aging property and therange of visible light penetration.
