SikaBiresin CR910 | Fast Cure Wind Blade Repair

SikaBiresin® CR910 is a high Tg composite resin system for wet lay-up processing. It is used where fast curing products for repair of wind blades are requested. SikaBiresin® CR910 is designed for repair of damaged laminate structures of rotor blades. It is optimized for hand lay-up but can also be used for repair of patches by vacuum infusion. This product is suitable for experienced professional users only. Tests with actual substrates and conditions must be performed ensuring adhesion and material compatibility.

A standard hardener (6180-C) or fast hardener (6045-C) can be used depending on the desired pot life and are sold separately.

The Sika Biresin mix pack contains pre-measured quantities of epoxy resin and hardener, sealed in pouches, ready for mixing. It contains no solvents or fillers and is primarily intended for hand lamination of composite parts. Simply remove the divider strip, mix resin and hardener together, and use. The convenient packaging eliminates the need for messy measuring and mixing supplies and ensures accurate ratios of resin-to-hardener every time.

  • High glass transition temperature
  • High stiffness and strength
  • Direct curing without waiting gel-time
  • Usable for hand layup in production and field repair
  • Resistant to crystallization at low temperature
