LS-8941 OPTICALLY CLEAR, HIGH DUROMETER SILICONE ELASTOMER
Description
- Two-part, optically clear, non-phenyl containing addition cure silicone
- Designed to stay thermo-optically stable with heat and UV exposure
- 24 hours minimum work time
- 80 Type A durometer aids with scratch resistance and reduces tackiness
Applications
- For molding or casting hard, non-yellowing lenses for LED, solar or other applications where a hard, optically-stable silicone is needed
- Viscosity is designed to be used with conventional Liquid Injection Molding equipment, and the material is self-leveling for casting application techniques
