Filed:

Feb 14, 1983

Appl. No.:

6/466259

Inventors:

Stanley E. Kendall - Wilmette IL

Assignee:

American Home Products Corporation - New York NY

International Classification:

C11D 1704

US Classification:

252 90

Abstract:

A rubbing compound compound concentrate suitable for dispensing as a foam from an aerosol container is made from 16 to 28 percent by weight of a soap moiety which has a soap solids of 8 to 18 percent by weight of the soap moiety, from 16 to 46 percent by weight of an adjuvant moiety of suspending agents, wetting agents, lubricants and odoring agents and from 17 to 50 percent by weight of an abrasive, preferably amorphous silica, having a maximum particle size of 55 microns and sufficient deionized water to produce a viscosity of 60 to 80 Krebs units. An aerosol composition is made from the concentrate and 5 to 10 percent by weight of a propellent sufficent to provide aerosol discharge while maintaining an in-can solids of 45 to 60 percent by weight. The process of making the concentrate comprises first forming in place the soap moiety and serially adding the adjuvants and abrasive while maintaining a penetrometer reading of 350 to 450 mm. in ASTM D217.

Abstract:

A combination scratch filler and primer for painted metal surfaces can be dispensed in an aerosol system. The composition has a high solids content and an anti-settling agent to make the solids readily dispersible even after long storage. The solids content is preferably 45 to 51 percent by weight of the concentrate and from 19 to 22 percent by weight of the concentrate, solvents and propellent. The anti-settling agent is present in a volume ratio to the solids of 1:10 to 1:50.
