Overview
ALITA 6322 Isophthalic-NPG Unsaturated Polyester Resin
Category：CIPP ResinCode：ALITA 6322
Applications
ALITA 6322 is an Isophthalic-Neopentyl Glycol (NPG) type unsaturated polyester resin specifically designed for Cured-In-Place Pipe (CIPP) trenchless rehabilitation.
- Core Properties: Features medium viscosity and exceptional photopolymerization reactivity, ensuring reliable curing even in thick-walled liner applications.
- Process Advantages: Excellent air-release (de-foaming) performance and superior wetting properties for glass fibers.
- Product Performance: Products manufactured with this resin exhibit extremely high mechanical strength and outstanding water resistance.
- Curing Flexibility: Supports both conventional chemical curing and UV light curing, providing high adaptability and flexibility for varied site requirements.
