LS-6143 by Avantor is a translucent, low viscosity, odorless, optical thermosetting silicone (SI) resin. It is available as two-part 10:1 mix ratio (Part A:B). It is a clear, room temperature vulcanizing (RTV) silicone based on a dimethyl-diphenyl copolymer. Suitable for applications requiring index matching at 1.43 and operating temperature range of -115°C to 260°C. LS-6143 is designed for bonding, casting or injection molding of high performance optical components. Recommended for photonics applications requiring low outgassing and minimal volatile condensables to avoid condensation in sensitive devices.
