SikaBiResin® CR-910 – Epoxy Resin System

SikaBiResin® CR-910 – Epoxy Infusion Resin System

SikaBiResin® CR-910 is a high-performance, low-viscosity epoxy infusion resin developed for the manufacture of large, high-load composite structures using vacuum infusion and RTM processes. When combined with SikaBiResin® CH 910-1 or CH 910-5 hardeners, the system delivers excellent flow behavior, reliable fiber wet-out, and consistent laminate quality in thick and complex parts.

Designed for demanding structural applications, the CR-910 system provides high mechanical strength, strong fiber adhesion, and excellent fatigue resistance. Its controlled reactivity allows manufacturers to select the appropriate hardener speed to suit part size, ambient conditions, and processing requirements.

Once cured, SikaBiResin® CR-910 offers excellent thermal stability and chemical resistance, ensuring long-term durability in harsh service environments. The system is widely used in wind energy, marine, transportation, and industrial composite applications where structural performance and process reliability are critical.
