  • Patent number: 6833398
    Abstract: Autodeposited coatings useful for protecting metal surfaces and in production of rubber-to-metal composites are obtained by curing adducts based on epoxy resins which are adhered to the metal surface. One or more epoxy resins, such as for example, the combination of a diglycidyl ether of bisphenol A and a flexibilizing epoxy resin, may be prereacted to form an adduct of higher average molecular weight than the starting epoxy resins. Said adduct may then be dispersed in water, with the resulting dispersion being used in an autodeposition bath composition.

  • Patent number: 6723765
    Abstract: Autodeposition compositions for polymeric coatings of reduced gloss are prepared using resins having at least one hydroxy group and at least one epoxy group per molecule, a low temperature crosslinker and a high temperature crosslinker. The low temperature crosslinker forms a reactive prepolymer that may be subsequently mixed or emulsified with a high temperature crosslinker to form an autodeposition composition. Alternatively, a hybrid crosslinking agent may be utilized which contains both free isocyanate groups reactive at a relatively low temperature with the resin and at least one functional group capable of reacting with the resin only at a relatively elevated temperature. When deposited and cured, the resulting coating has a matte finish that is resistant to surface defects.

  • Patent number: 6685851
    Abstract: The present invention relates to the use of cycloaliphatic diamines as cosolvents for hydrophobic amines in aqueous solution. The cycloaliphatic diamines of the present invention have a formula: where n is 1 or 2, each R is independently selected from a group consisting of: hydrogen, a 1 to 6 carbon aliphatic, and a 0 to 6 carbon containing amine, wherein each R is chosen such that the cosolvent amine comprises at least two amine groups; and a quantity of water to maintain said solution as a homogeneous phase. The cosolvent diamines have particular utility in the formation of water based epoxy resin curing agents. Superior water miscibility is achieved for hydrophobic amines through the use of cycloaliphatic amines as compared to conventional cosolvents.
