摘要： A waterborne thermoset cured anticorrosion formulation includes a water dispersed or emulsified phosphonated or water dispersed or emulsified sulfonated epoxy resin that is cured with a phenoxy resin having a polyhydroxyl ether backbone and terminal alpha glycol moieties. Water is present as a predominant volatile in which the epoxy resin and phenoxy resin are present in a weight ratio of epoxy resin to phenoxy resin of between 0.1 and 3:1. An aqueous curative is provided to induce cure between the epoxy resin and phenoxy resin, A corrosion inhibiting metal salt is also present having a salt anion of phosphate, biphosphate or tetraborate and a metal cation with the proviso that the metal cation formulation as a whole is devoid of chromium, lead, cobalt, and cadmium. Ideal curatives include aqueous aminoplast crosslinkers, aqueous unblocked isocyanates, aqueous blocked isocyanates, and a mixture thereof. With the inclusion of electrically conductive aluminum or zinc particulate the formulation is rendered corrosion resistant as well as electrically conductive to make an inventive coating amenable to powder coating.

摘要： A polyester-based coating composition capable of forming a striated pattern on a metal surface at a film thickness less than half of that of PVC plastisol films is provided by a thixotropic composition having a thix index of from about 1.5 to about 3 and comprising a hydroxy-functional polyester, a thixotropy-inducing rheologic agent and curing agent. The striated coating is applied to sheet metal in a coil coating operation by introducing the composition into a paint pan of a coil coater, transferring said composition from said paint pan to an applicator roll by rotating a pick-up roll in contact with the composition and with said applicator roll; continuously withdrawing a sheet of metal from a coil thereof and coating said sheet by contacting it with the applicator roll; curing the coating on said sheet by passing the sheet through an oven at an elevated temperature; and continuously rewinding said sheet into a coil.

The hydroxyl value is from about 150 to about 275, and the acid number is less than about 7. Substantially all of the hydroxy groups are primary and from 0 to about 5% of the hydroxy groups are present as pendant hydroxy-alkyl groups. The polyester is formed by a two-stage reaction of monomers consisting of carboxylic anhydrides having from 4 to 34 carbon atoms and polyols having from 2 to 20 carbon atoms. From about 10 to about 50% by weight of the monomers are anhydrides having the formula: ##STR1## where R.sup.1 is a non-aromatic hydrocarbon radical having from 6 to 30 carbon atoms, R.sup.2 is hydrogen or a non-aromatic hydrocarbon radical having from 1 to 8 carbon atoms. The total number of carbon atoms in R.sup.1 and R.sup.2 is from 8 to 30 carbon atoms. The polyester in conjunction with a hydroxyl-reactive curative provides a coating composition.

摘要： An essentially linear polyester oligomer having hydroxyl and carboxyl terminal groups for subsequent cure and its production are disclosed. This polyester oligomer is produced by first adducting approximately equimolar amounts of diol carrying two primary hydroxyl groups and a dicarboxylic acid anhydride to form an hydroxy acid. The carboxyl groups of this hydroxy acid are then esterified by reaction with an approximately stoichiometric proportion of diol carrying one primary hydroxyl group and one secondary hydroxyl group, the stoichiometry being based on the total hydroxyl content of the diol and the carboxyl content of the hydroxy acid, to form an hydroxyl-terminated oligomer. This hydroxyl-terminated oligomer is then adducted with a polycarboxylic acid monoanhydride having a carboxyl functionality of at least 3, this monoanhydride being used in an amount of 0.01 to 0.15 equivalents of anhydride per hydroxyl equivalent in the hydroxyl-terminated oligomer. The resulting polyester oligomer is essentially linear and possesses low solution viscosity at high resin solids content combined with high reactivity enabling low temperature cure with aminoplast resins.
