Filed:

Apr 19, 2007

Appl. No.:

11/788679

Inventors:

Kamlesh Gaglani - Belle Mead NJ, US
Meihua Yang - Hillsborough NJ, US
Gordon Thakkar - Edison NJ, US

Assignee:

Troy Corporation - Florham Park NJ

International Classification:

C08K 5/1565

US Classification:

524108

Abstract:

Non-yellowing degassing compositions which enhance degassing in powder coatings and other film-forming curable coatings are disclosed. The non-yellowing compositions contain degassing agents including a plurality of unfused aromatic rings and at least one functional group selected from ketals, carbamates, carbonates and carboxylic acid esters. The degassing agents resist decomposition and discoloration, and are relatively stable at resin curing conditions and. The degassing agents may be synergistically combined with other materials, such as fatty acid amide-containing waxes, to produce new and surprisingly effective degassing compositions suitable for use in powder coatings. Curable compositions which utilize the new degassing compositions are also disclosed.

Filed:

Jul 2, 2008

Appl. No.:

12/217222

Inventors:

Kamlesh Gaglani - Belle Mead NJ, US
Meihua Yang - Hillsborough NJ, US

International Classification:

A01N 59/16
C08K 3/38
A01P 3/00

US Classification:

424641, 523122

Abstract:

A broad spectrum antimicrobial composition comprising a mixture of an iodopropynyl compound in combination with a benzimidazole and a metal borate is disclosed. The composition can be used to protect industrial systems against microbial growth and, more particularly, to protect substrates such as paints, coatings, stucco, concrete, stone, cementaceous surfaces, wood, wood-plastic composites, caulking, sealants, textiles, leather, wood, preservatives, metal working fluids, drilling muds, clay slurries, glazes, optical brighteners, carpet backing, and pigments against microbial growth. The composition can be used as a preservative for aqueous products.
