A newly developed polyaryl ether amide resin system, particularly suitable for use in structural components, to be sold under the brand name CALIDUR® will be launched shortly by Evonik Industries. This single-component system is particularly suitable for applications in aircraft manufacturing. Because of its improved fiber adhesion, the product improves the mechanical properties of bonded fiber materials to create components with both high compressive strength and shear strength. The material stands out for its high temperature resistance, low moisture absorption, and good resistance to chemicals, as well as low exotherm and minimal shrinkage in the curing process.
Fabrics treated with CALIDUR® also are significantly more flame retardant than those treated with conventional epoxy resins. As a result, CALIDUR® is suitable for interior aircraft applications in the aerospace industry, especially since the system is formaldehyde free. CALIDUR® also features good shelf-life stability at room temperatures and an excellent price-performance ratio.
