US Patent:

8298441, Oct 30, 2012
Filed:

May 22, 2008
Appl. No.:

12/125520
Inventors:

Owen P. Kasson - Cleveland OH, US
Robert A. Martuch - Parma OH, US
Celestine O. Ilori - South Euclid OH, US
Glenn A. Miller - Fairview Park OH, US
Daniel M. Gerow - Avon OH, US
Assignee:

The Sherwin-Williams Company - Cleveland OH
International Classification:

C09D 5/22
US Classification:

25230136, 524457, 524403, 524437
Abstract:

Stable, phosphorescent, water-based coating compositions include a latex emulsion, at least one metal aluminate pigment as a source of phosphorescence, and an effective buffering amount of a buffering agent, which may be an organic acid. The ratio of metal aluminum phosphorescent pigment to latex binder in the latex emulsion may be in the range of about 0. 5:1 to about 2. 0:1. The effective amount of buffering agent may be from about 0. 1% to about 10% with respect to emulsion weight. Compositions according to the present invention may have useful shelf lives of six months or longer. Methods of using the phosphorescent latex coatings and coated substrates are also taught.

International Classification:

C09D 5/16
C09D 101/26
US Classification:

523122000, 106197010
Abstract:

A low VOC, HAPs free, substantially non-aqueous slurry for use as a rheology modifier in aqueous systems including but not limited to latex paints.
