Appl. No.:

12/261726

Inventors:

MARK W. PRESSLEY - Cary NC, US
Kirk J. Abbey - Garner NC, US
Sandra L. Case - Holly Springs NC, US

International Classification:

B05D 3/00
C08K 5/01

US Classification:

427331, 524474, 524481

Abstract:

An adhesive composition is provided which is capable of bonding to metallic surfaces which are contaminated with oil or oily residue. An adhesion improving additive is added to the base adhesive/coating composition which enables the adhesive to achieve better bonding to oily substrates. Addition of the adhesion improving additive improves the adhesion of adhesives, sealants, and coatings to the oily substrates used in the automotive and industrial markets. The an adhesion improving additive is an aliphatic molecule of at least 8 carbon atoms or having an aliphatic end group or side chain of least 6 carbon atoms, and wherein the adhesion improving additive comprises a boiling point of at least 30 C.

Abstract:

The present invention provides crosslinked polyester compositions for use in coating metal. The polyester comprises residues of at least one aromatic acid; 2,2,4,4-tetramethyl-1,3-cyclobutanediol and at least one polyol different than 2,2,4,4-tetramethyl-1,3-cyclobutanediol wherein the polyester has a glass transition temperature greater than 75 C., an acid value of 1 mg KOH/g to 6 mg KOH/g, and a number average absolute molecular weight of 4000 g/mol to 18000 g/mol. The compositions are useful for coating metal surfaces for food contact applications and are particularly useful for coating metal can ends.
