Features Of Chan Chem TB-570 Polyester Resin

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

  2. Excellent thixotropic behavior enabling superior sag resistance in vertical and overhead applications.

  3. Low styrene emission formulation supporting improved workplace safety and regulatory compliance (VOC < 35% w/w).

  4. Consistent batch-to-batch performance with tightly controlled acid number and viscosity specifications.

  5. Good compatibility with common fillers, pigments, and fiberglass reinforcements without phase separation.

Typical Applications Of Chan Chem TB-570 Polyester Resin

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

  2. Marine hulls, decks, and structural components requiring moisture resistance and dimensional stability.

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

  4. Wind turbine blade bonding and structural adhesives in composite assembly.

  5. Architectural cladding panels and translucent roofing systems.
