Features Of Chang Chun ETERSET 2517P Unsaturated Polyester Resin

  1. High reactivity with standard MEKP initiators for rapid gelation and efficient production cycles.

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

  3. Good resistance to water, weak acids, and alkalis in ambient conditions.

  4. Low viscosity (250–350 mPa·s at 25°C) enabling easy fiber wet-out and high filler loading capacity.

  5. Consistent batch-to-batch quality with controlled acid value and styrene content for reliable processing.

Typical Applications Of Chang Chun ETERSET 2517P Unsaturated Polyester Resin

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

  2. Pultruded profiles for construction and infrastructure reinforcement.

  3. Sheet molding compound (SMC) for automotive body panels and electrical enclosures.

  4. Centrifugal casting pipes for municipal water and wastewater systems.

  5. Marine deck components and boat hull laminates requiring moderate corrosion resistance.
