    摘要: An anionic polyacrylamide pretreatment for a metal surface which enhances corrosion resistance and surface adhesion properties is described. The pretreatment is stable at extreme pH's and compatible with other water soluble polymers. The anionic polyacrylamide includes mono- or di-alkyl substitutions on the N group of the polyacrylamide.

    摘要: A process for measuring the coating weight of a dried-in-place non-chromate polyacrylamide based conversion coating is disclosed. An ammonium hexafluorotitanate tracer added to such a conversion coating was found to not adversely affect coating properties. The tracer was found to remain proportional to the polymer matrix when the coating was analyzed by X-ray fluorescence.

    摘要: A process for measuring the coating weight of a dried-in-place non-chromate polyacrylamide/surfactant based conversion coating is disclosed. An ammonium hexafluorotitanate tracer added to such a conversion coating was found to not adversely affect coating properties. The tracer was found to remain proportional to the polymer matrix when the coating was analyzed by X-ray fluorescence.
