Hycat™ Catalysts have been the best-kept secret in the epoxy/anhydride pultrusion industry for more than two decades. These breakthrough catalysts dramatically reduced curing temperatures and increased epoxy/anhydride pull speeds — from 8–10 inches per minute in the early 2000s to 50–60 inches per minute today.

With regulatory pressures mounting on the use of styrene and methacrylates, the pultrusion industry is reaching a crossroads regarding the continued use of vinyl ester and polyester resins.

Manufacturers now face three choices:

1. Incur the cost and potential liability of complying with exposure limitations and continue working with substances that could eventually be classified as carcinogenic.
2. Adopt styrene alternatives that may be less reactive, more expensive, and could compromise product performance.
3. Change the chemistry — and take advantage of the low VOC, low odor, low shrinkage, high speed, and enhanced mechanical properties available with epoxy/anhydride resin systems.

Dimension Technology Chemical Systems (DTCS) offers a range of proven Hycat™ products that can be readily implemented, or we can collaborate with you to custom-formulate a catalyst package tailored to your specific processing requirements.

Additionally, DTCS can work directly with your preferred anhydride supplier to preload the catalyst to your specifications, eliminating the need to procure, inventory, and blend the product on-site.
