Abstract: The invention relates to an aqueous cathodic electrocoating material which contains a synthetic resin binder containing amino and/or hydroxyl groups and capable of being rendered water-soluble by the addition of an acid. The synthetic resin binder contains a mixture of crosslinking agents, as well as pigments, fillers, corrosion inhibitors, surface coating assistants, if appropriate catalysts, and organic solvents in an amount of up to 15% by weight, based on the total weight of the coating material. The mixture of crosslinking agents consists of at least two crosslinking agents which possess different reactivities and are based on activated esters and/or polyisocyanates blocked with different blocking agents. Different reactivities means that the crosslinking reactions begin at temperatures which are at least 10.degree. C. apart. The crosslinking reagent which reacts first is present in an amount of from 15 to 60 mol %, based on the mixture of crosslinking agents.

Abstract: An improved multifilamentary tow of carbon fibers is provided which possesses a novel physical configuration that better enables it to undergo impregnation with a matrix-forming resin to form quality composite articles. The individual filaments of the tow are randomly decollimated and commingled with numerous filament cross-over points throughout the length of the multifilamentary tow in order to create a multitude of interstices between adjacent filaments which are well adapted to receive and retain a matrix-forming resin as evidenced by the ability of the filaments when subjected to the flaring test described herein to resist lateral expansion to a width that is as much as three times the original width. The tow commonly comprises approximately 1,000 to 50,000 filaments. Also, the filaments of the tow are substantially continuous and contain at least 70 percent carbon by weight (preferably at least 90 percent carbon by weight).
