| 摘要 |
Disclosed herein is a precursor powder composition comprising a resin, a combination of zinc dust, zinc powder and zinc-coated microspheres and graphite, said powder being soluble in a solvent blend at a facility remote from the powder manufacturing facility, thereby, decoupling the powder manufacturing process from the end use of the powder which could be in a traditional solvent-based paint. Also disclosed are coating compositions for use in protecting metallic substrates from corrosion, comprising necessary additives and film forming substances including alkyl silicate, epoxy resins, powder and non-powder, and polyester resins, all the compositions being modified with about 4 to about 20 weight percent graphite powder based on total weight of the composition. |
