Due to the increase of LED applications and the need of transparent encapsulation copaltec offers colourless and crystal clear PU Casting Resins. The excellent transparency makes the Resin perfect for the highest demands on optical properties.
We have tested the weather resistance of our Casting Resins in the Northern European climate. The samples were exposed over 10.000 hours to weathering. The results show exceptionally good UV light stability. The non-yellowing and optical clarity could be maintained throughout the test period.
