Product Description
Duroptix™ OE-6550 A/B Kit is a two-part, 1:1 mix ratio silicone encapsulant formulated for LED packaging and encapsulation applications. Based on methylphenyl siloxane chemistry, this material combines high optical transparency, a refractive index of 1.54, and thermal stability for demanding lighting environments. The cured silicone exhibits 100% transparency at 450 nm (1 mm thickness) and is designed to accommodate stresses generated during thermal cycling, helping protect LED chips and bonding wires. Compatible with standard dispensing and molding processes, Duroptix™ OE-6550 A/B Kit supports efficient manufacturing while delivering optical and electrical properties required for LED device performance.
