The present invention is directed to a process for producing micropulp. The process includes contacting organic fibers with a medium comprising a liquid component and a solid component, agitating the medium and the organic fibers to transform the organic fibers into the micropulp dispersed in the medium. If desired, the slurry of the micropulp in the liquid component can be used or the micropulp can be separated from the medium. The micropulp can be readily incorporated into coating compositions such as those used in automotive OEM or refinish applications. The micropulp can also be incorporated into powder coating applications or as a thixotrope or reinforcement in polymer formulations.

The present invention relates to a weldable pre-primed coating composition, comprising binder resins, a crosslinker, an anti-corrosive pigment, conductive metal powder, carbon nanotubes, etc. The coating composition can be applied to a metal sheet before processing of the metal sheet to maximize the weldability, adhesion, corrosion resistance and processability of the metal sheet. Also, the coating composition can be applied to a metal sheet by a roll coating process to make it possible to eliminate not only an existing electrodeposition process which is carried out by a non-environmentally-friendly wet dipping process, but also an existing electrostatic spray primer coating process which is carried out by an electrostatic spray coating process in which a solvent is scattered, whereby the metal sheet coated with the coating composition has very excellent formability and weldability after its processing. Accordingly, the composition makes it possible to reduce the number of complex automotive coating processes, thereby greatly contributing an increase in productivity, a reduction in energy and an improvement in a work environment.
