  • Patent number: 5744531
    Abstract: An anionic electrocoating composition is provided including an electrodepositable .beta.-hydroxyalkylamide curing agent and an electrodepositable polymer capable of crosslinking with the curing agent. This curing agent includes an organic radical that (a) contains from 8 to 60 carbon atoms; (b) is derived from a substituted or unsubstituted aliphatic, alicyclic or aromatic hydrocarbon radical; and (c) is bonded to n .beta.-hydroxyalkylamide groups, wherein n is an integer from 1 to 4, to form ##STR1## where R.sup.1 can be H or a substituted or unsubstituted aliphatic, alicyclic or aromatic group containing up to 6 carbon atoms;where R.sup.2 and R.sup.3 can be the same or different and can be H or a substituted or unsubstituted aliphatic, alicyclic, or aromatic group containing up to 36 carbon atoms;where R.sup.4 can be H or a substituted or unsubstituted aliphatic group containing up to 8 carbon atoms when n is an integer form 2 to 4, and a .beta.

  • Patent number: 5530043
    Abstract: A pigment grind composition contains pigment, water dispersible acrylic polymer and a reactive diluent. The reactive diluent has a number average molecular weight of between about 200 and about 2500 and is selected from polyalkylene glycols, polyalkylene glycol ethers, glycol ether formals or mixtures of these. The pigment grind composition has a volatile organic content of less than two pounds per gallon.

  • Patent number: 5492614
    Abstract: A method of electrocoating an electroconductive substrate utilizes an aqueous electrocoating composition containing an electrodepositable water dispersible film forming polymer and a pigment grind composition. The pigment grind composition contains pigment, electrodepositable water dispersible acrylic polymer and a reactive diluent. The reactive diluent has a number average molecular weight of between about 200 and about 2500 and is selected from polyalkylene glycols, polyalkylene glycol ethers, glycol ether formals or mixtures of these. The pigment grind composition has a volatile organic content of less than two pounds per gallon. The method is particularly suitable for anodic electrodeposition.
