Features Of Chang Chun ETERSET 2446T Unsaturated Polyester Resin

  1. High reactivity with standard peroxide initiators, enabling fast gel times and efficient production cycles.

  2. Excellent mechanical strength and dimensional stability after curing, suitable for structural composite applications.

  3. Good resistance to water, weak acids, and alkaline environments in cured form.

  4. Low viscosity for easy handling, wet-out of reinforcements (e.g., glass fiber), and improved mold filling.

  5. Consistent batch-to-batch quality with strict process control per Chang Chun’s ISO 9001-certified manufacturing.

Typical Applications Of Chang Chun ETERSET 2446T Unsaturated Polyester Resin

  1. Fiberglass-reinforced plastic (FRP) tanks and vessels for chemical storage.

  2. Pultruded profiles including rods, channels, and gratings for construction and infrastructure.

  3. Sheet molding compound (SMC) components for automotive under-hood and exterior parts.

  4. Centrifugally cast pipes and manholes for municipal wastewater systems.

  5. Marine deck cores and non-structural hull components requiring balanced performance and processability.
