BYK Launches Coupling Agent for Improved Carbon Fibers

Published on 2018-02-23. 

  

BYK launches BYK-C 8013 is a solvent-free, polymeric coupling agent for improving the mechanical strength of carbon-fiber-reinforced, radical-curing systems, and it is the world’s first coupling agent for carbon fibers.

BYK-C 8013 Increases Strength by up to 70 Percent

It is used in vinyl esters and unsaturated polyester resins that are processed to composite parts using carbon fibers. The cross-fiber strength is greatly improved, making far greater design freedom possible.

Properties & Applications


  • BYK-C 8013 increases both the transverse tensile strength and the flexible strength of the composite by means of improved fiber-matrix bonding.
  • The chemical structure of the additive provides simultaneous adhesion to the fiber and to the resin matrix.
  • This unique property makes changes in the component design possible, and it enables particularly durable components to be manufactured.
  • Especially in hot-curing processes such as SMC/BMC, pultrusion, prepreg or RTM, BYK-C 8013 brings about increases in strength of up to 70 percent.
  • The reactive additive can be introduced to the size during fiber production or to the resin shortly before processing.
  • In subsequent, so-called “second sizing”, BYK-C 8013 can, for example, be applied to the fiber in a spraying process, without the need to remove the first coat beforehand.
  • This innovative additive will be unveiled and premiered before a trade audience at Booth E40 in Hall 5a of the JEC in Paris from March 6 to 8.
