Overview
ALITA 853 Pre-accelerated Unsaturated Polyester Resin
Category：Crafts ResinCode：ALITA 853
Applications
ALITA 853 is a pre-accelerated orthophthalic unsaturated polyester resin synthesized from phthalic anhydride, maleic anhydride, and standard glycols. It features medium viscosity and low reactivity.
- Properties: Noted for light color, exceptional transparency, low shrinkage, and stable curing. Pure resin products appear crystal clear with excellent yellowing resistance.
- Applications: Widely used for imitation crystal, imitation stained glass, frosted glass, and other high-end artistic crafts.
