Overview
ALITA 852 Unsaturated Polyester Resin
Category：Crafts ResinCode：ALITA 852
Applications
ALITA 852 is an orthophthalic unsaturated polyester resin synthesized from phthalic anhydride, maleic anhydride, and high-quality glycols. Pre-dissolved in cross-linking monomers like styrene, it features medium viscosity and low reactivity, making it easy to handle.
- Properties: Noted for light color, high transparency, low shrinkage, and a stable curing process.
- Applications: Ideal for manufacturing general transparent crafts, providing superior aesthetic appearance and reliable performance stability.
