What Are Unsaturated Polyester Resins?

These resins result from combining polyols with both saturated and unsaturated dibasic acids. Because of their unsaturation, they can undergo cross-linking when mixed with styrene or other reactive monomers. Consequently, they transform into solid, durable, and chemically resistant thermoset plastics. Their versatility and ease of use make them a popular choice across various industries.

Applications Across Many Industries

1. Composite Reinforced Plastics (GRP)
   Our Unsaturated Polyester Resins are key binders in glass-reinforced pipes, tanks, ducts, and sheet molding compounds (SMC). They create strong, lightweight, and weather-resistant composite components used in water treatment, infrastructure, and transportation.

2. Cultured Marble & Surface Products
   Resin blends with crushed marble to create decorative countertops, wall panels, and bathroom fixtures. These applications benefit from the resin’s high gloss and stain resistance.

3. Marine & Wind Energy Applications
   Boats, yachts, and wind turbine parts rely on Unsaturated Polyester Resins for structural integrity. These polymers deliver excellent moisture resistance and UV tolerance in marine and offshore environments.

4. Transportation & Construction
   Resins go into train interiors, truck panels, and architectural moldings. Their light weight, robustness, and aesthetic finish make them ideal for both indoor and structural installations.

5. Coatings & Paints
   Modified grades serve as raw form for wood coatings, primers, and specialty paints, offering adhesion, flexibility, and protective properties.
