This award winning moldable optical silicone is a medium viscosity, high Shore A hardness, fast heat curing optical molding resin for producing optical parts with good resistance to environmental aging. It has a smooth, low-tack, plastic-like surface and enables the molding of complex, finely detailed optical parts and secondary lenses. It remains relatively soft after injection molding, with high elongation capability for easy demolding of complicated parts, such as those designed with a combination of thick and thin areas (e.g., lens clusters). After demolding and post-curing, it reaches its final mechanical properties and produces hard and tough optical parts. It shows enhanced stability of optical performance upon high heat, high humidity and UV exposures, meeting the most demanding requirements for outdoor lighting applications.
