Process additive for improving the wettability of reinforced fibers [BYK-P 9920]
Process additive for improving the wettability of reinforcing fibers [BYK-P 9920] - By adding BYK-P 9920 to the resin, it is possible to reduce entrapped bubbles and voids, thereby achieving a decrease in defect rates during molding and a reduction in repair processes. • Using the appropriate additive can enhance impregnation and prevent the occurrence of voids. • It improves adhesion with the resin and can suppress delamination at the fiber surface after curing. • By preventing impregnation defects and voids, and enhancing adhesion with fibers, it can reduce variability in the strength of the final product and improve reliability.
