Abstract: Non-gelled amine-epoxide reaction products are obtained by co-reacting a secondary amine, a polyoxyalkylene polyamine, a polyepoxide and optionally a monoepoxide. The products are crosslinkable and are useful in aqueous coating compositions, particularly when applied to a substrate by cathodic electrodeposition.

Abstract: A process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter.The formation of aggregates of granules in the large scale production of granules using a metal oxide, hydroxide or weak acid salt as base can be overcome by using a surfactant which comprises a species ##STR1## wherein a=5-12, X is an anion of pK.sub.1 less than 2 and R is an alkylene oxide chain composed of units selected from ethylene, propylene and butylene oxides. When alkylene oxide other than ethylene oxide is present in the chain, such alkylene oxide must not provide more than two units per chain and the chain must additionally comprise at least three ethylene oxide units.The granules prepared by the process are useful as matting and opacifying agents in, for example, coating compositions.

Abstract: This invention relates to a process of preparing aqueous slurries of vesiculated granules of crosslinked polyester resin wherein the granules have a maximum shrinkage on drying of 5% of the granule diameter. Previously-known processes for the preparation of granules of this type have utilized polyamines; this has led to odor and color problems. These problems may be eliminated or substantially reduced by the use of bases which are metal oxides, hydroxides or salts wherein the metal cation is selected from Ca, Mg, Ba, Ti, Zn, Pb, Sr and Co and, when a metal salt is used, the pKa value of the conjugate acid of the anion is greater than 2. The resulting granules are useful at matting and opacifying agents in, for example, paint compositions.
