Evonik’s New Single-Component Resin System

25 September 2009

This year’s SAMPE will give Evonik Industries the opportunity to showcase its newly developed polyaryl ether amide resin system, Calidur.

According to manufacturers, the product has enhanced fibre adhesion, which allows it to improve the mechanical properties of bonded fibre materials to create components with both high compressive strength and shear strength.

Because of these improvements, Calidur should be suitable for use in structural components; the material boasts high temperature resistance, low moisture absorption, and good resistance to chemicals, as well as low exotherm and minimal shrinkage in the curing process.

In addition to this, Evonik say that fabrics treated with Calidur also are significantly more flame retardant than those treated with conventional epoxy resins. As a result, the product is suitable for interior aircraft applications in the aerospace industry, especially since the system is formaldehyde free.
