Features Of Chang Chun ETERSET 2426 Unsaturated Polyester Resin

  1. Excellent balance of mechanical strength and impact resistance for structural composite parts.

  2. Low viscosity (250–350 cP at 25°C) enabling superior fiber wet-out and efficient resin transfer molding (RTM) processing.

  3. Good heat distortion temperature (HDT ≈ 85–90°C) after post-curing, supporting mid-temperature service applications.

  4. Consistent reactivity profile with standard MEKP initiators, ensuring reliable gel time control in ambient and warm-cure operations.

  5. High solids content (>99%) with low styrene emission potential, contributing to improved workplace safety and VOC compliance.

Typical Applications Of Chang Chun ETERSET 2426 Unsaturated Polyester Resin

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

  2. Automotive body panels and under-hood components requiring dimensional stability and surface finish.

  3. Marine deck structures, hull liners, and recreational boat components.

  4. Industrial grating, cable trays, and corrosion-resistant ductwork.

  5. Pultruded profiles for construction reinforcement and infrastructure applications.
