  • Patent number: 6849328
    Abstract: A method and coating are provided for temporarily protecting a substrate or article during shipping, handling or storage by applying a removable protective coating over at least a portion of the substrate. The substrate may be flat or curved and may have zero, one or more functional coatings. A plurality of substrates with the protective coating of the invention may be arranged in a shipping container so that the protective coating reduces the possibility of damage to the substrate or optional functional coating. In one embodiment, the protective coating is the evaporation or reaction product of an aqueous coating composition containing a polyvinyl alcohol polymer which may be subsequently removed by aqueous washing, thermal decomposition or combustion. In another embodiment, the protective coating is formed by sputtering a substantially carbon coating onto the substrate. The carbon coating is subsequently removed by combustion.

  • Patent number: 6592998
    Abstract: Improved multi-layer composites are provided. The multi-layer composites include at least a first polymeric layer and a second polymeric layer formed over the first polymeric layer thereby forming an interface region there between. At least one of the polymeric layers is formed from a thermosetting composition which contains an adhesion promoter composition. The adhesion promoter composition is formed from (1) at least one adhesion promoting component, and (2) at least one surface active component. The improvement is represented by the presence of the adhesion promoting component (1) at the interface region.

  • Publication number: 20020127343
    Abstract: An apparatus for forming a graduated coating on a substrate includes a coating station positioned along a conveyor. The coating station includes a first coating dispenser pivotally mounted on a first support and at least one exhaust hood. The first coating dispenser is positioned such that an axis through the delivery end of the first coating dispenser subtends the substrate at a predetermined angle. A method for forming a graduated fade zone on a substrate surface includes positioning a coating dispenser adjacent one side of the substrate, angling the coating dispenser toward the other side of the substrate and supplying a coating material to the coating dispenser such that the coating material is deposited onto the substrate to form a graded fade zone on the substrate.

  • Patent number: 4891111
    Abstract: Cationic electrocoating compositions comprising a cationic electrodepositable resin and particular hydroxyl-free, alkylated polyethers dispersed in an aqueous medium are disclosed. Due to the presence of the polyethers, the compositions electrodeposit at high film builds with good smoothness. However, the polyethers do not result in detrimental effects with regard to the properties of the compositions such as rupture voltage and corrosion resistance of the resultant electrodeposited film. Also, the particular polyethers readily incorporate in the electrodeposition bath, are non-volatile and do not significantly build up in the electrodeposition bath during the electrodeposition process.

  • Patent number: 4605478
    Abstract: Formaldehyde-containing cationic electrodepositable compositions to which are added a formaldehyde scavenger are disclosed. Also disclosed are the use of these compositions in a method of cationic electrodeposition. Free formaldehyde in cationic compositions can lower the pH of the compositions making them more corrosive to the metal parts such as ferrous metal tanks and attending piping and pumps in contact with such compositions. The presence of the formaldehyde scavenger in such compositions stabilizes the pH.

  • Patent number: 4530945
    Abstract: A quaternary ammonium group-containing material and its method of preparation are disclosed. The quaternary ammonium group contains at least one organic group which contains an acyclic group of at least 8 carbon atoms and also contains a group of the structure ##STR1## wherein R.sub.1 is hydrogen or lower alkyl. The quaternary ammonium group-containing materials are useful as pigment grinding vehicles and in the formulation of pigment paste, particularly pigment paste with high pigment loadings. When formulated in cationic electrodepositable compositions, the pigment grinding vehicles provide for cured electrodeposited coatings of excellent corrosion resistance, particularly over untreated and oily steel.

  • Patent number: 4147679
    Abstract: A water-diluted, ungelled, non-sedimenting polyurethane and a process for preparing such a polyurethane in an aqueous medium is disclosed. High molecular weight thermoplastic products are obtained by chain extending in aqueous medium an NCO polymer having a salt group equivalent weight of 6000 or less and substantially free of reactive hydrogen. The average functionality and equivalent ratio of the polyisocyanate and active hydrogen-containing materials used in making the NCO polymer, as well as the functionality of the chain extender, are carefully controlled so as to get high molecular weight ungelled products. Thermosetting compositions can be made by adding curing agent to the chain extended material. Curing agents can also be incorporated into the polymer molecule either in the making of the partially reacted NCO-containing prepolymer or by further reaction with the partially reacted NCO-containing prepolymer.

  • Patent number: 4098743
    Abstract: Water-soluble polylactones and poly(lactone-urethanes) are disclosed. The polylactones are prepared by ring opening a lactone such as epsilon-caprolactone with a low equivalent weight active hydrogen-containing material having at least two active hydrogen groups per molecule selected from the class consisting of hydroxyl, primary amine, secondary amine and thiol, and having anionic water-solubilizing groups or groups which are readily reacted to form anionic water-solubilizing groups. The resulting polylactone can be combined with curatives such as amine-aldehyde condensates to form water-soluble coating compositions and can be reacted with polyisocyanates to form unique water-soluble poly(lactone-urethanes, ureas or thiolurethanes) which are also useful for coating applications.
