US Patent:

41136500, Sep 12, 1978

Filed:

Aug 4, 1975

Appl. No.:

5/601628

Inventors:

Edgar N. Putman - New Hope PA
George Patterson - Philadelphia PA
Scotty Wimer - Bethlehem PA
John B. McCool - Ottsville PA

Assignee:

PFD/Penn Color, Inc. - Doylestown PA

International Classification:

B01F 300

US Classification:

2523635

Abstract:

A combination of an aryl sulfonamide-formaldehyde resin and film forming material, such as cellulose acetate butyrate, which may further include a surfactant, such as a non-ionic surfactant including, for example, an alkylarylpolyether, comprises a "universal" dispersant for resin additives, such as pigment materials. This composition generally includes 40-90 weight % of any of various types of additives, including pigments. The dispersant generally comprises from 30-80 weight % film former or binder, which may consist of cellulose acetate butyrate or a solid plasticizer, such as camphor, sucrose benzoate and dicyclohexylphthalate, and from 20-70 weight % of the aryl sulfonamide-formaldehyde resin. Apart from pigments, the additives may consist of fillers, extenders, etc. , including, for example, calcium carbonate, antimony oxide and magnesium silicate.

International Classification:

C08L 114

US Classification:

260 15

Abstract:

A novel, durable thermosetting acrylic automotive finish and method for manufacturing same is described which is manufactured from a predispersed, substantially dry composition. The resultant thermosetting acrylic finish has a higher pigment loading at a sprayable viscosity, thereby reducing the number of applications necessary to produce an acceptable automotive finish. In tests conducted by applicants, the described thermosetting acrylic automotive finish exhibits acceptable durability when exposed to solar radiation for extended periods of time.
