Definitions

composition used according to the present methods may further comprise one or more additives standard in the art, such as coalescence solvents, plasticizers, dispersing agents, wetting agents, light stabilizers, surfactants and catalysts.
additives standard in the art, such as coalescence solvents, plasticizers, dispersing agents, wetting agents, light stabilizers, surfactants and catalysts.
additives if used, will typically comprise 0.001 to 5 weight percent, based on the total solid weight of the coating.
the present invention is further directed to methods for preparing a full panel easy open end comprising stamping an end from a metal sheet and electrodepositing on the end an electrodepositable coating. At least one surface of the end is substantially uncoated prior to the electrodeposition step.
the metal may be lubricated prior to stamping, such as by using a commercially available lubricant. Suitable lubricants are available from PPG Industries, Inc. Typically, the lubricant is cleaned from the metal following stamping. Again, any conventional cleaner can be used to remove the lubricant, such as acidic or alkaline cleaners commercially available from PPG Industries, Inc.
a second electrocoat would be desired to minimize the possibility of any blister points or touch points that may have been created during cure of the first coat.
a single coat of electrodepositable coating on the full panel easy open end will give suitable enamel rater test results.
the methods of the present invention can consistently result in ends giving enamel rater readings of less than 25 milliamps, such as less than 10 milliamps or even less than 5 milliamps. While a second electrocoat can be used according to the present invention, it is a feature of the present invention that no additional coat needs to be used over top of the electrocoat according to the present methods.
the need to do a repair on an end is minimized, if not eliminated, because the part is stamped prior to coating.
the present invention represents a significant savings in both time and materials as compared with conventional methods, in which one, two or even three coats are applied to a metal sheet, the end is stamped, and repair of the coating is required.
the present invention is further directed to a full panel easy open end prepared according to any of the methods disclosed herein.
This example illustrates the preparation of a polyester-graft-acrylic copolymer.
Polyester “A” is Carried out as follows: TABLE 1 Ingredients Parts by Weight Charge #1 1,3-Butylene Glycol 177.1 Ethylene Glycol 34.4 Charge #2 1,4-Cylcohexanedicarboxylic Acid 259.6 Isophthalic Acid 107.2 Maleic Anhydride 18 Dibutyltin Oxide 1.19 Methyl Hydroquinone 0.054 Charge #3 Xylene 27.2 Charge #4 Xylene 188.7
the determined acid value was 2.1 mg KOH/gram, and hydroxy value was 20.9 mg KOH/gram.
the determined non-volatile content of the resin was 69.9% as measured by weight loss of a sample heated to 110° C. for 1 hour.
Analysis of the polymer by GPC (using linear polystyrene standards) showed the polymer to have an M w value of 10,115, M n value of 2,798, and an M w /M n value of 3.6.
Polyester-graft-acrylic Copolymer “B” is Carried out as follows: TABLE 2 Ingredients Parts by Weight Charge #1 Propylene Glycol Monomethyl Ether 184.0 Charge #2 Propylene Glycol Monomethyl Ether 43.2 t-Amylperoxy-2-Ethyl Hexanoate 16.2 Charge #3 Butyl Acrylate 77.8 2-Hydroxyethyl Methacrylate 90.7 Methacrylic Acid 77.1 Styrene 16.2 2-Ethylhexyl Acrylate 32.4 Methyl Methacrylate 29.8 Polyester A 1080.0 Propylene Glycol Monomethyl Ether 48.6 Charge #4 Propylene Glycol Monomethyl Ether 16.2 t-Amylperoxy-2-Ethyl Hexanoate 3.2 Charge #5 Propylene Glycol Monomethyl Ether 16.2 t-Amylperoxy-2-Ethyl Hexanoate 3.2 Charge #6 Propylene Glycol Monomethyl Ether 102.8
Charge #1 was added to a round-bottom, 4-necked flask equipped with a motor driven stainless steel stir blade, water cooled condenser and a heating mantle with a thermometer connected through a temperature feed-back control device. The contents of the flask were heated to reflux temperature. The addition of Charges #2 and #3 were started simultaneously and continued over 3 hours. After the additions were complete, the reaction was held at 120° C. for 30 minutes. Charge #4 was then added to the mixture and after 60 additional minutes, Charge #5 was added. After Charge #5 was added, the mixture was held for 60 additional minutes, and Charge #6 was added.
This example illustrates the preparation of an acrylic polymer.
polyester-graft-acrylic copolymer “B” To a suitable container equipped with agitation was added 93.8 g of polyester-graft-acrylic copolymer “B”. To this was then added 40.0 g of GPRI 7590 (Georgia-Pacific) phenolic resin solution. When completely mixed 6.8 g of N,N′-diethylethanolamine was added under agitation followed by a very slow addition of 1859.4 g of deionized water.
the resulting coating was electrodeposited on tinplated 207.5 easy open ends.
the electrodeposition took place at a voltage of 245 volts over a 3 second dwell at a bath temperature of 77° F.
the ends were baked in a gas fired oven at an oven temperature of 410° F. for 3 minutes, to give a film weight of ⁇ 8 mg/in 2 .
the resulting ends were tested for film integrity using a Wilkens-Anderson WACO Digital Enamel Rater (See Table 5). Average Enamel Rater values less than 3 milliamps, with no single value greater than 5, were targeted.
polyester-graft-acrylic copolymer “C” To a suitable container equipped with agitation was added 91.8 g of polyester-graft-acrylic copolymer “C”. To this was then added 40.0 g of GPRI 7590 (Georgia-Pacific) phenolic resin solution. When completely mixed 9.5 g of N,N′-diethylethanolamine was added under agitation followed by a very slow addition of 1858.7 g of deionized water.
