UV Stabiliser for epoxy

UV Stabilizer for epoxy
UV Stabilizer for epoxy
  • Protection against yellowing
  • Only 1% required
  • Suitable for all epoxy resins

In the long term, epoxy castings may yellow due to UV radiation. Hardener forms the most important property for yellowing resistance. Hardeners like RESION Epoxy coating and RESION Epoxy resin have good UV resistance. However, we recommend using a UV blocker, especially for outdoors applications. This significantly prolongs the UV resistance of a casting.

Tip: are you looking for UV stable epoxies to which you do not need to add a UV blocker? Then use RESION UV EpoxyEpoxy for large castings or UV Resin Art epoxies!

Benefits of UV stabiliser for epoxy

  • Considerably increases the UV stability of epoxy
  • Easy to process
  • You only need 1% stabiliser of the total weight of epoxy

Instructions for use

Add about 1% of this UV stabiliser to the total weight of epoxy casting resin and hardener. This way you extend the UV resistance and protect the casting from discolouration by sunlight. You can mix the UV blocker into the epoxy resin beforehand or add it to the mixture after mixing.

The UV stabiliser does not affect the colour or transparency of the epoxy.

Please note: the UV stabiliser may become hard/thick due to temperature fluctuations (crystallisation). When you heat the UV stabiliser, it should liquefy and is suitable for use. If in doubt, please contact us.
