LightFair International Technical Innovation Award

This award-winning moldable silicone provides excellent properties and secondary optics solutions for LED lamp/luminaire applications. Its curing speed is optimized for the injection molding process of silicone rubber. It is especially suitable for precision molding applications, as micrometer-sized features can be replicated on the lens surface to direct light output, enabling lighting companies to design optics for luminaires with high lumen efficiency. High thermal stability ensures the retaining of high transparency – even in harsh environments.
