Volvo XC90 composite transverse leaf springTo meet the requirements for automated, short production cycles of composite components, Henkel says it has developed Loctite Max 2 composite matrix resin for RTM processes.

The company claims this two-part polyurethane-based product is fast curing, and because of its low viscosity, rapidly fills the mould and quickly, resulting in short injection times. A post cure can also be performed to ensure a full cure in around one hour at 150°C.

This polyurethane matrix resin has enabled automotive specialist Benteler-SGL, to develop a glass-fibre-reinforced leaf spring with a projected production output of over 100,000 parts per year.
