Supporting Composite Molders Who Use DCPD Resins

Within the composite molding industry there are many different resins that may be utilized, and Chem-Trend has developed products that are designed to complement the characteristics of each type of resin. Often, polyester, vinyl ester, epoxy, phenolic, polyether and DCPD resins are used by fabricators in the manufacture of composite parts. The choice of resin is based upon the conditions that the fabricated part will face, as well as the desired characteristics for the end part. The specific physical and mechanical properties of the resins are key parameters in the selection process.

The selection of a specific type of resin has a strong influence on the required properties of the mold release agent/release system. The number of releases obtained between applications of semi-permanent release agent touch-up coats will vary from resin to resin. DCPD resins are generally in the middle of this range.

Aside from just the effect on release ease, and time between release agent touch up or reapplication, the resin selected may also influence other release system parameters, which can also affect end part quality, operational efficiency and mold life. Chem-Trend has over two decades of experience helping composite molders understand the interactions between molding process, raw materials being molded, part shape/weight, mold type and environmental factors to select the optimum release system for the task at hand.
