Evonik Launches Two Polyamide-based Epoxy Curing Agents for Americas Region

Ancamide® 2853 and Ancamide® 2865 deliver high flexibility with standard diluted epoxy resin. This eliminates the need for polyurethane modifiers. The curing agents also offer high tensile and tear strength along with fast curing speeds. This makes them ideal for applications requiring quick return to service. Additionally, they are nonylphenol-free and utilize bio-based raw materials with a bio-content of 20-40%. This composition makes them safer and more eco-friendly compared to typical flexible nonylphenol-containing epoxy curing agents that do not use bio-based raw materials.

"Our customers are navigating stricter labelling requirements, and we are dedicated to providing solutions that not only meet these standards, but also deliver the exceptional performance they rely on," said Dr. Kevin Wohlhauser, regional head of the Civil Engineering market segment of Evonik Crosslinkers in the Americas. "By utilizing bio-based raw materials, these nonylphenol-free products offer a safer and more eco-friendly option, exemplifying our commitment to innovation and sustainability."

Both of these new curing agents are ideal for civil engineering and flooring applications where coatings are subjected to frequent movement and stress. Their fast-curing speed minimizes downtime. This makes them suitable for scenarios where efficiency is critical. Specific applications include deck overlays, flexible membranes, crack bridging, joint sealants, and flexible grouts.

"In addition to being ideal for applications requiring rapid turnaround times, our customers also find Ancamide® 2853 and Ancamide® 2865 very easy to use. Formulators have maximum flexibility to customize their products by adjusting the mix ratio of part A and part B," said Dr. Shiying Zheng, regional applied technology director of the Civil Engineering market segment of Evonik Crosslinkers in the Americas, whose team developed these products.
