Articles having a plurality of pouches present in a single article, the pouches separately containing chemical materials which are capable of providing a reactive mixture mixed, that cures over time to provide a polymeric coating in certain embodiments. The chemical materials are maintained in separate pouches that are separated by one or more frangible seals. When a frangible seal is broken, such as by application of pressure to the article, the chemical materials in the separate pouches come into contact with one another and may be mixed together. Subsequent to their mixing, the mixture formed is removed from the article, such as by cutting the article with scissors, and applied to any substrate that is desired to be coated, when the chemical materials are selected to be capable of forming a cured coating subsequent to their mixture.

1. An article useful for containing plural components of a mixture in distinct compartments and their subsequent mixing within said article, comprising: a first layer of material;a second layer of material sealingly attached to said first layer along a first seal; anda frangible seal along which said first layer of material is sealingly attached to said second layer of material, said frangible seal being configured and located sufficiently to define a first pouch having a first interior volume and at least a second pouch having a second interior volume in said article, said first pouch containing a first substance and said second pouch containing a second substance that is chemically reactive towards said first substance, said substances yielding upon their admixture a mixed composition from which a cured polymeric material selected from the group consisting of: polyurethane polymers, polyurea polymers, epoxy polymers, acrylic polymers, and polyaspartic polymers may be provided, wherein the strength of said frangible seal is less than that of said first seal by an amount sufficient to enable a person to apply pressure to one of said pouches causing rupture of said frangible seal and admixture of said first and said substances, without causing said first seal to rupture, and wherein said first seal has a strength sufficient to not be ruptured until a pressure differential of at least 7.5 psi is caused to exist between a volume within said article and ambient pressure. 2. An article according to claim 1 wherein said frangible seal is of sufficient strength to not be ruptured under ambient conditions until a first pressure differential exceeding two pounds per square inch is caused to exist between the interior volumes of said first pouch and said second pouch, and wherein the strength of said first seal is sufficient to not be ruptured under ambient conditions until a second pressure differential exceeding that required for rupture of said frangible seal by at least one pound per square inch is caused to exist between a volume within said article and the ambient pressure, subsequent to rupture of said frangible seal. 3. An article according to claim 1 wherein said first seal comprises a continuous loop. 4. An article according to claim 1 wherein said first pouch is bounded by a portion of said first layer, a portion of said second layer, said first seal and said frangible seal. 5. An article according to claim 1 wherein said second pouch is bounded by a portion of said first layer, a portion of said second layer, said first seal, and said frangible seal. 6. An article according to claim 1 comprising a tape layer structure disposed between said first layer and said second layer. 7. An article according to claim 6 wherein said tape layer structure comprises at least one polymeric material. 8. An article according to claim 1 wherein said first layer of material is attached to said second layer of material at a tape layer structure present between and in contact with each of said layers along said first seal and said frangible seal. 9. An article according to claim 1 wherein at least one of said first layer and said second layer comprises at least one polymeric material. 10. An article according to claim 1 wherein each of said first layer and said second layer have a perimeter, and wherein said first seal is located substantially along the perimeter of said first layer and said second layer. 11. An article according to claim 1 wherein said mixed composition is in a liquid state suitable for use as a coating to be applied to a substrate. 12. An article according to claim 1 wherein said article includes a re-sealable closure along at least any one selected segment of the perimeter of said article. 13. An article according to claim 12 wherein said first seal comprises a frangible portion along its length and is adjacently disposed to the location of said re-sealable closure, sufficiently to enable said article to be re-sealed after rupture of said adjacently-disposed frangible portion. 14. An article according to claim 1 wherein said article is substantially rectangular as viewed from an overhead perspective, being about 45 centimeters long and about 25 centimeters wide, wherein said first pouch has a volume that is in the range of between 300 milliliters and 500 milliliters, and wherein said second pouch has a volume that is in the range of between 800 milliliters and 1200 milliliters. 15. An article according to claim 1 wherein said article is substantially rectangular as viewed from an overhead perspective, being about 45 centimeters long and about 25 centimeters wide, wherein said first pouch has a volume of about 500 milliliters and wherein said second pouch has a volume of about one liter. 16. An article according to claim 1 wherein the width of said first seal is any width in the range of between about three millimeters and about forty millimeters. 17. An article according to claim 1 wherein the width of said frangible seal is any width in the range of between about one millimeter and about forty millimeters. 18. An article according to claim 17 wherein the width of said frangible seal is any width in the range of between about one millimeter and about forty millimeters. 19. An article according to claim 1 further comprising a second frangible seal sufficiently disposed so as to cause three separate pouches to exist in said article between said layers. 20. An article according to claim 19 wherein said frangible seal and said second frangible seal each rupture upon being subjected to different levels of applied pressure, which levels are different than the pressure required to rupture said first seal.
