Stable, compatible, resin fortified aqueous vinyl polymer emulsions that are rich in wax are prepared in a method comprising a first polymerization of a mixture containing wax and monomers that include carboxylated monomers such as acrylic acid. The first polymerization or terpolymerization is carried out under conditions sufficient to produce a relatively low molecular weight resin. A portion of the wax rich resin from the first polymerization is neutralized and used as a cosurfactant in a second aqueous emulsion polymerization of vinyl monomers to produce a fortified vinyl latex that is rich in wax. Coatings prepared from the latex exhibit superior moisture barrier properties and are also useful as surface preservatives.

Process for the production of stable high wax content vinyl latices

A low-foaming resin-fortified latex comprising a dispersed acrylic polymer, polyelectrolyte resin and a non-ionic emulsifier with an HLB value of 13 or less.

Low-foaming latexes for use in printing ink formulations

Cathodic electrodepositable resin compositions and aqueous electrodeposition coating baths comprising these resins are disclosed. The resin compositions comprise a cationic amine epoxy resin adducts and a cationic polyurethane resin adduct dispersion. The resin compositions when combined with a cross-linking agent and cathodically electrodeposited produce films which cure to durable, flexible, smooth corrosion-resistant, impact and chip-resistant films.

Cationic electrodepositable resin compositions containing polyurethane

A coating composition is produced particularly adapted for use on the interior of food containers, and specifically metal cans which contain proteinaceous foods. In addition to being nonstaining the particular coating composition is steam resistant and flexible. It is also water dilutable and storage stable. The polymer consists of a reaction product of a plurality of acrylic monomers in the presence of a high molecular weight epoxy resin, a phenolic resin, and a free radical initiator dissolved in a water miscible solvent. The solution is rendered water dilutable by the addition of aqueous amine which neutralizes the carboxyl functionality of the acrylic monomers.
