DCPD Resins

Low Viscosity. Low Shrinkage. High Performance.

Our dicyclopentadiene (DCPD) modified polyester and vinyl ester resins are engineered for excellent processability, reduced shrinkage, and dimensional stability, making them ideal for large parts and cost-efficient composite manufacturing.

Enhanced Processing for Composites Manufacturing

DCPD resins are specialty unsaturated polyester resins modified with dicyclopentadiene. This modification provides:

  • Lower viscosity: easier handling and faster wet-out of reinforcements.

  • Reduced shrinkage: better dimensional accuracy in molded parts.

  • Improved economics: cost-effective performance for large-scale applications.

 

At Happy Composites, we distribute ISO 9001:2015 certified DCPD resins in the U.S., combining enhanced performance with logistics you can rely on.
