Optically clear silicone encapsulants

When using LEDs, good heat planning is important to achieve the optimal operating temperature and amount of light. Sensitive LED components should be protected from humidity and other environmental impacts.

Optically clear gel-like silicones or harder optical silicones are suitable for most LEDs that require to be able to see the component under silicone without losing the light efficiency.

CHT’s silicone gels can withstand even the drastic thermal expansion of the components due to their softness. It also provides strong protection against vibration and various mechanical shocks. The adhesion of silicone gels is excellent, which ensures a visually impressive LED product. Thanks to its low viscosity, the material fills tight spaces and offers a bubble-free application.
