Gel Silicones
Two-part, optically clear, heat curable gels or elastomers. Typical silicone beneļ¬ ts include non-yellowing, high light transmittance, and a high refractive index for LED chip encapsulation. Other applications may include, but are not limited to: coating optical devices and semi-conductors; absorbing shock and protecting delicate mechanical components from vibration. |
