BYK® -C 8013

BYK®-C 8013 by BYK is a solvent-free polymeric coupling agent to increase the mechanical strength of carbon fiber-reinforced and radical-curing systems. The additive results in improved mechanical properties of the final part through increased fiber-matrix bonding. The extent of the increase depends on the choice of the carbon fiber and matrix system. In hot-curing methods, such as SMC/BMC, pultrusion or RTM, the additive shows considerable increase in strength. BYK®-C 8013 can be used with both vinyl ester- and epoxy-sized fibers. The additive can be applied as a second sizing to the fiber e.g. in a spraying process, without having to remove the first sizing. The recommended level for addition to the size is 1-10% additive (as supplied) based upon the size, second sizing: 3-10% additive (as supplied) based upon the carbon fiber and addition to the resin: 1-10% additive (as supplied) based upon the resin. The shelf life of this product is 24 months.
