Product features and advantages

VOK®- C 8001 is specially applied to glass fiber reinforced epoxy resin systems. The additive improves the mechanical properties of components by increasing the fiber matrix bonding. The degree of improvement depends on the choice of glass fiber and epoxy resin systems.

Recommended dosage

1-3% of auxiliary dosage (purchased form) is based on the general formula.

Adding method and processing guidance

VOK®- C 8001 can be added to both curing agent and epoxy resin, but it should be added to epoxy resin before construction. The additive can be stored in standard amine curing agent. The longest storage time is affected by the composition of curing agent and the amount of additives.
