What is HALS and UV stabilization?

Posted on 12 Apr 08:26
  • Epoxy resins are prone to yellowing and other degradative effects from UV light, so stabilization additives are used to help mediate the damage. A UV stabilizer works to protect against gloss loss, cracking, chalking and de-lamination, and to some extent yellowing. A UV stabilizer merely delays yellowing in resins, so ArtResin has a HALS (hindered amine light stabilizer) added for extremely efficient long term yellowing protection.
