US Patent:

7396891, Jul 8, 2008

Filed:

Feb 3, 2005

Appl. No.:

11/050271

Inventors:

Richard Thomas Gray - Levittown PA, US
Alan Wayne Kohr - Schwenksville PA, US
Dennis Michael Sharpe - Quakertown PA, US
Theodore Tysak - Ambler PA, US

Assignee:

Rohm and Haas Company - Philadelphia PA

International Classification:

C08F 20/06

US Classification:

5263171, 526318, 526309, 526346

Abstract:

Aqueous coating compositions containing (1) a first polymer containing reactive functional groups with a selected level of carboxylic acid functionality and (2) a polyfunctional crosslinker agent containing functional groups that are reactive with appropriate functional groups of the first polymer, are disclosed. The two-component polymer compositions provide a combination of durability and ready removability of the final coating after curing. Two-component polymer compositions based on the first polymer containing hydroxyl functionality in addition to carboxylic acid functionality and use of a polyisocyanate as the polyfunctional crosslinker agent are especially useful as floor polish compositions.
