Appl. No.:

10/400165

Inventors:

Shelby D. Worley - Auburn AL, US
Yongjun Chen - Auburn AL, US
Jia-Wang Wang - Auburn AL, US
Rong Wu - Auburn AL, US
Yanjun Li - Kirkland WA, US

Assignee:

Vanson Halosource, Inc. - Redmond WA

International Classification:

C08G077/24

US Classification:

548110, 556425, 556413, 528 28, 528 38, 428447

Abstract:

Heterocyclic and acyclic silane monomers and siloxane polymers, and their halogenated derivatives, are provided for the purpose of functionalizing surfaces or materials so as to render them biocidal upon exposure to oxidative halogen solutions. The biocidal function can be imparted either before or after bonding or adhesion to the surface or material. The biocidal surfaces and materials can then be used to inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as virus particles, which can cause infectious diseases, and those microorganisms which cause noxious odors and unpleasant coloring such as mildew. Examples of surfaces and materials which can be rendered biocidal in this invention include, but are not limited to, cellulose, chitin, chitosan, synthetic fibers, glass, ceramics, plastics, rubber, cement grout, latex caulk, porcelain, acrylic films, vinyl, polyurethanes, silicon tubing, marble, metals, metal oxides, and silica.

International Classification:

C07F 5/02

US Classification:

548110000

Abstract:

N-halaminehydantoinyl epoxide compounds which can be used for the construction of coatings and materials which can be rendered biocidal by exposure to halogen solutions either before or after curing the coating or material are disclosed. The biocidal coatings and materials can then be used to inactivate pathogenic microorganisms such as bacteria, fungi, and yeasts, as well as virus particles, which can cause infectious diseases, and those microorganisms which cause noxious odors and unpleasant coloring such as mildew. The coatings are compatible with a variety of substrates including, but not limited to, cellulose, chitin, chitosan, synthetic fibers, cement grout, latex caulk, acrylic films, polyurethanes, plastics and paints.
