Overview
ALITA 132 Orthophthalic General Purpose Polyester Resin (Marine/Auto Grade)
Category：Hand Lay-up ResinCode：ALITA 132
Applications
ALITA 132 is a pre-accelerated, thixotropic general-purpose unsaturated polyester resin. It is primarily synthesized from phthalic anhydride, propylene glycol, and styrene.
- Features: Low viscosity, good glass fiber wetting properties, and excellent thixotropic processing performance. Cured products exhibit good mechanical strength.
- Certification: Certified by the China Classification Society (CCS).
- Applications: Suitable for hand lay-up or spray processes to produce various FRP products, such as:
- Transportation: FRP vehicles and components.
- Marine: Fishing boats, yachts, lifeboats.
