Master Bond's new MS151 optical adhesive has been specially formulated for optimal optical bonding. It is a two-part silicone adhesive which combines silicone's inherent temperature resistance and flexibility with a refractive index of 1.43 and superb optical clarity. Its low viscosity assures complete fill-in around complicated contours even in very complex configurations. These key factors recommend the use of the silicone adhesive for optical potting, casting and encapsulation applications.

Master Bond MS 151 cures at room temperature to an optically clear silicone rubber, providing excellent electrical insulation as well as superior resistance to vibration, impact, shock and thermal cycling. Shrinkage upon cure is less than 0.1%.

The uniquely formulated optical adhesive is designed to optimize optical bonding to glass, metals, ceramics and fiberglass optical systems as well as coating solar cells and fiber optic assemblies.

This transparent adhesive has a dielectric strength of 460 volts/mil and a volume resistivity of 1x10E15 ohm-cm. Tough, yet flexible bonds exhibit an elongation-at-break of 160%. The operating temperature range is impressive, from ‑65°F to +400°F (‑64°C to 205°C). MS 151 optical adhesive is suitable for complex applications wherever and whenever a tough, elastic and optically transparent protection against adverse environmental conditions is required.
