6368677, Apr 9, 2002

Filed:

May 15, 2001

Appl. No.:

09/855267

Inventors:

Michael A. Hubbard - Somerset NJ
James A. McCaulley - Clinton NJ
Douglas R. Holcomb - South Orange NJ

Assignee:

Hoechst Trespaphan GmbH - Neunkirchen

International Classification:

B05D 138

US Classification:

427534, 427536, 427307, 427309, 427340, 4274123, 4274197

Abstract:

A method for providing a waterborne, inorganic barrier coating to a polyolefin substrate is described. The method involves applying a primer composition containing a vinyl polymer, wherein at least 75% of the polymer repeat units contain side groups having hydroxyl moieties, to the substrate. This primer coating facilitates the application and binding of the subsequently applied barrier coating composition to the substrate.

Appl. No.:

8/870575

Inventors:

James A. McCaulley - Clinton NJ
Michael A. Hubbard - Somerset NJ

Assignee:

Hoechst Trespaphan GmbH

International Classification:

B32B 904

US Classification:

428 357

Abstract:

A vapor barrier coating solution for poly(ethylene terephthalate) (PET) polymeric articles contains a metal polysilicate and transparent nanocrystalline titanium dioxide. The coating reduces interference between light reflected from the top surface of a coated PET polymeric article and the interface between the dried coating and said PET polymeric article. The coated articles are also provided.

Assignee:

Hoechst Trespaphan GmbH

International Classification:

C09D 518
B32B 2700

US Classification:

428 345

Abstract:

A vapor barrier coating solution for polymeric articles is provided which contains a selected layered silicate dispersed in a cationic aqueous metal polysilicate, wherein the weight fraction layered silicate of total inorganic solids in the dry coating ranges from above 0 to about 99 percent. Preferably the layered silicate is vermiculite and the polysilicate is lithium polysilicate. Methods for producing and using this coating solution are also included.

US Classification:

428336

Abstract:

A barrier-coated polyester film comprises a polyethylene terphthalate substrate, a primer composition containing a vinyl polymer wherein at least 75% of the polymer repeat units contain side groups having hydroxyl moieties, and a waterborne, inorganic barrier coating. The primer coating facilitates the application and binding of the subsequently applied waterborne barrier coating composition to the substrate.

Assignee:

Hoechst Trespaphan GmbH

International Classification:

B32B 904
B32B 1304

US Classification:

428446

Abstract:

A method for coating polymeric substrate articles with a barrier coating that imparts improved vapor, gas or aroma permeability characteristics to the coated substrate, without efflorescence or hazing of the dried coating. The method employs a lithium-potassium copolysilicate of the formula (L. sub. 2 O). sub. x (K. sub. 2 O). sub. 1-x (SiO. sub. 2). sub. y, wherein y is between 1 and 10, if x is less than 1; or y is greater than 4. 6, if x is 1.

Abstract:

A method and novel barrier coating solutions are provided for imparting improved vapor, gas or aroma permeability characteristics to a coated polymeric substrate. The method and solutions employ a lithium-potassium copolysilicate of the formula (Li. sub. 2 O). sub. x (K. sub. 2 O). sub. 1-x (SiO. sub. 2). sub. y. For the method, y is between 1 and 10, if x is less than 1; or y is greater than 4. 6, if x is 1. For the novel coating solutions, y is greater than 4. 6 if x is less than 1; or x is greater than 0. 5 if y is between 1 and 10.
