  • Patent number: 5332776
    Abstract: A blend of from 10 to 90 parts by weight of a basic calcium sulphonate free of calcium carbonate in the calcite form and from 90 to 10 parts by weight of a terpolymer of 80 to 99 wt.% of an olefin containing from 2 to 4 carbon atoms, 1 to 30 wt.% of an unsaturated ester which is a vinyl ester of a carboxylic acid or an ester of acrylic or methacrylic acid and 1 to 20 wt.% of an unsaturated carboxylic acid is particularly useful for car undercoatings for corrosion and chip resistance which may be applied as high solids coatings.
    Type: Grant
    Filed: October 7, 1992
    Date of Patent: July 26, 1994
    Assignee: Exxon Chemical Patents Inc.

  • Patent number: 5283276
    Abstract: A corrosion protection composition a dispersion or solution of (a) colloidal size amorphous overbased sulfonate, (b) solvent or plasticizer, and (c) polymeric material soluble in the solvent or compatible with the plasticizer is disclosed. The composition comprises at least about 70% solids, by weight, and the particle size if the colloidal overbased sulfonate is up to about 100 A. Preferably, the composition is free from any mineral oil. Metal surfaces having the herein disclosed composition applied thereto, or having the applied thereto the composition from which the solvent has been removed also is disclosed.
