Filed:

Sep 19, 2000

Appl. No.:

09/665024

Inventors:

Gary P. Craun - Berea OH
Kenneth G. Hahn - Hinckley OH
George P. Rosekelly - Norwalk OH

Assignee:

The Glidden Company - Cleveland OH

International Classification:

C08F12068

US Classification:

526318, 526335, 524514, 524556, 524564

Abstract:

An ambient dry water dispersed coating composition substantially free of volatile organic coalescing solvents, the coating composition containing a polymer film forming binder comprises between 40% and 50% copolymerized non-conjugated, unsaturated fatty acid triglyceride, between 40% and 55% copolymerized ethylenic monomer including styrene, and between 3% and 12% copolymerized maleic anhydride. The film forming copolymer is produced by first reacting maleic anhydride with the fatty acid triglyceride at high temperatures between 140Â C. to form a maleinized triglyceride having a pendent maleic anhydride structure. The maleinized triglyceride is then styrenated at temperatures between about 80Â C. and 200Â C. in the presence of at least 4% peroxide initiator based on the weight of monomers copolymerized to form a styrenated, maleinized fatty acid triglyceride copolymer having anhydride groups.

International Classification:

C09D 17/00
C08K 5/06
C09D 103/14

US Classification:

106501100, 106499000

Abstract:

Encapsulated colorants for waterborne coating compositions are provided as a system and kit with a method for tinting the water borne coating compositions. The encapsulated colorant comprises at least one water dispersible tinting material to be released into the based coating composition upon dissolution of the encapsulating layer to give the coating composition color. The encapsulating layer surrounding the colorant has at least one polymer that is soluble in aqueous medium surrounding the tinting material wherein the layer has a thickness from about 0.5 to about 5 mils and can dissolve to release the dispersible tinting material in an aqueous coating composition having about 25 to about 45 volume percent solids and about 55 to about 75 volume percent water in less than 15 minutes with agitation at a temperature in the range of about 50 to about 110 F. One or more of the encapsulated colorants as a pouch or pouches are contained in a moisture resistant package until ready for dissolution in the coating composition. A plurality of the encapsulating colorants as pouches in moisture resistant packaging comprise a system which along with one or more clear or tint base water borne coating compositions comprise a kit. A method involves placing one or more pouches in a volume of coating composition with stirring or shaking to provide a color to the composition.

Assignee:

The Glidden Company - Cleveland OH

International Classification:

C08L 1302

US Classification:

523310

Abstract:

A stabilized aqueous, thermosetting coating composition substantially free of acid cure catalysts comprises a mixture of an ion-exchanged reactive function emulsion polymer and a glycoluril derivative adapted to coreact and crosslink the functional polymer where certain cations are added to the ion-exchanged mixture to provide a pH of the mixture between 2 and 5.

Appl. No.:

7/432814

Inventors:

Kenneth G. Hahn - Hinckley OH
Barbara L. Kunz - Bay Village OH

Assignee:

The Glidden Company - Cleveland OH

International Classification:

C08L 6100

US Classification:

524512

Abstract:

The pigmented paint coating composition is based on a cationic free polymeric binder comprising a cationic free, functional emulsion polymer and glycoluril where the emulsion polymer are adapted to coreact to form a thermoset paint film, and said polymeric binder is combined with a low-cation opacifying pigment. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers but excluding amine monomers, in an aqueous polymerization medium, to produce the reactive emulsion polymer. The emulsion polymer and the glycoluril derivative are treated with ion-exchange step to produce the cation-free polymeric binder.

US Classification:

524555

Abstract:

Thermosetting low temperature cure coating compositions produced by combining certain emulsion polymers containing reactive hydroxyl groups, carboxyl groups, and acrylamide groups with a dimethylol dihydroxy ethylene urea whereby the hydroxyl groups cross-link with the dimethylol dihydroxy ethylene urea upon curing. Preferred emulsion polymers are acrylamide polymers.
