Opti-tec 4200 is an optically clear potting compound suitable for encapsulating LEDs and other electronic components. Opti-tec 4200 is a clear polyurethane resin for applications including lighting, illumination or when the electronics needs to be visible. It features excellent non-yellowing colour stability owing to UV resistant base materials and stabilisers. In double syringe or twinpack sachets, the encapsulant is easy to mix and apply, and cures to a clear, scratch resistant finish.
