Silicone primer

This product is a modified, single-component platinum-cured silicone rubber thermal‑molded primer, appearing as a colorless to pale yellow transparent liquid. The standard process involves degreasing, coating, and baking at 100°C for 10–15 minutes. This organosilicon primer serves to protect the silver‑plated layer of LED beads from sulfurization, offering high hardness, excellent high‑temperature resistance, and superior anti‑sulfurization performance.
