Does UltraClear Epoxy contain HALS (non-yellow UV stabilization )?

Yes! Our Art & Craft formula includes advanced UV stabilization technology designed for excellent non-yellowing performance, comparable to top artist-grade resins with HALS. This ensures your sculptures, resin art, and colorful projects stay crystal clear over time.

Details on HALS

HALS stands for Hindered Amine Light Stabilizer. It is an advanced additive used in premium epoxy resins to protect against yellowing over time. HALS works by neutralizing free radicals created by UV exposure, including indirect indoor light, and it continuously regenerates itself so the protection does not wear out. Basic UV absorbers only slow initial damage and can degrade over time, but HALS interrupts the yellowing process at its source, helping maintain long lasting clarity and color stability.
