Features Of Chan Chem EL-3650N Polyester Resin

  1. High reactivity with standard MEKP catalysts for rapid gel time control in ambient-cure processes.

  2. Excellent thixotropic stability—minimizes sagging and slumping during vertical or overhead application.

  3. Low styrene emission formulation, supporting improved workplace air quality and regulatory compliance (VOC < 380 g/L).

  4. Superior mechanical strength retention after water immersion, ideal for demanding marine and outdoor environments.

  5. Broad compatibility with common fillers, pigments, and fiberglass reinforcements without compromising dispersion or cure integrity.

Typical Applications Of Chan Chem EL-3650N Polyester Resin

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

  2. Marine hulls, decks, and superstructures requiring high hydrolytic resistance.

  3. Industrial corrosion-resistant linings and secondary containment systems.

  4. Wind turbine blade structural components and nacelle housings.

  5. Architectural cladding panels and translucent roofing systems.
