World class silicones for worldwide solutions

Optically Clear Silicone Encapsulants


Product Listing

LED, photovoltaic and other light sensitive devices require UV stable non-yellowing encapsulants for protection and improved light transmission.

The table below shows our range of addition cure silicones that are temperature and moisture resistant, as well as non-yellowing and UV stable. Of special note is QSil222 which is self-bonding to a wide range of substrates without the use of a primer.
