A two-part, 1 to 1 mix ratio, optically clear silicone encapsulant is suitable for solar cell encapsulation where extreme environments must be tolerated and longevity is valued. This product can be used for various solar cell encapsulation processes at room temperature, including casting and vacuum laminating. The two part mixture cures at room temperature or with mild heat to a flexible elastomer. The low viscosity, self-leveling, and long pot life make this an excellent process friendly option. This product is UL 94 and UL 746C f1 recognized.
