| abstract |
A system for treating a substrate comprising a deoxidizing composition and a coating composition is disclosed. The deoxidation composition may comprise a homopolymer or copolymer comprising a Group IVA metal and/or a Group IVB metal and free fluoride, optionally comprising phosphorus-containing monomeric subunits, and has a pH of from 1.0 to 3.0. . The coating composition includes first and second components and elastomeric particles. The first component includes an epoxy-containing compound. The second component comprises a diamine and/or a polyamine comprising a cyclic ring. The diamine may be chemically reacted with the epoxy-containing compound. The present invention also relates to a method of making the composition, a method of coating a substrate, and a coated substrate. |
