Hybrid latex emulsions are disclosed which can be used in the formation of coating compositions having good blush resistance, abrasion resistance, blister resistance, hardness and scratch resistance. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Hybrid latex emulsions of the invention may be prepared by mixing an ethylenically unsaturated monomer component and a stabilizer in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form the hybrid latex emulsion. The ethylenically unsaturated monomer component may include an organosilane compound, which may include a reactive organic group and a hydrolysable inorganic alkoxysilane.

Hybrid latex emulsions and coating compositions formed from hybrid latex emulsions

Coating compositions are disclosed. In some embodiments, the coating compositions are used to coat substrates such as packaging materials and the like for the storage of food and beverages. The coating compositions can be prepared by reacting an epoxidized vegetable oil and a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, mixing the hydroxyl functional oil polyol (with or without epoxidized polybutadiene) with a functional polyolefin copolymer to form a mixture, reacting the mixture with an ethylenically unsaturated monomer component in the presence of an initiator to form a graft copolymer, and crosslinking the graft copolymer with a crosslinker to form the coating composition.

Solvent-based coating compositions

Coating compositions are disclosed. In some embodiments, the coating compositions are used to coat substrates such as packaging materials and the like for the storage of food and beverages. The coating compositions can be prepared by reacting an epoxidized vegetable oil and a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, mixing the hydroxyl functional oil polyol (with or without epoxidized polybutadiene) and a functional polyolefin copolymer to form a mixture, reacting the mixture with an ethylenically unsaturated monomer component in the presence of an initiator to form a graft copolymer, and crosslinking the graft copolymer with a crosslinker to form the coating composition, wherein the graft copolymer or the crosslinked graft copolymer is inverted into water.

Water-based coating compositions

Latex emulsions are disclosed which can be used in the formation of coating compositions that are not water sensitive, have good blush resistance and retortability. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Coating compositions of the invention may be prepared by polymerizing at least one ethylenically unsaturated monomer component, a stabilizer comprising a strong acid and an initiator in a carrier to form an emulsion, polymerizing the emulsion with at least one different ethylenically unsaturated monomer component to prepare the composite latex emulsion, and reacting the composite latex emulsion with a neutralizer to form the coating composition. Methods of coating substrates with the coating compositions, and substrates coated with the coating compositions are also disclosed.

Latex emulsions and coating compositions formed from latex emulsions

A protective coating composition and a method for coating a metal substrate are provided. The composition and method are particularly suitable for coating can ends. The coating composition includes a film-forming polymer that includes an epoxy-based resin, a lubricant system, and a solvent or water component or mixture of solvent and water. The lubricant system includes a first surface modifier that reduces the coefficient of friction and a second surface modifier that reduces the abrasion of the cured coating.

Coating composition having improved release properties and the process for making the same

A solvent-born coating composition and process for wet-on-wet application to a metal substrate comprises a fluorocarbon resin, an acrylic resin, and various flow modifiers such as benzoguanamine resins, blocked isocyanates or polymeric urethanes. Such coatings used as a primer composition in conjunction with a fluorocarbon-containing topcoat impart improved corrosion resistance, substrate and intercoat adhesion and improved edge pullaway properties.

Polyvinylidene fluoride coatings

A heat-curable aqueous coil coating primer for priming metal coil comprises a film-forming binder phase comprising a heat-curable, water-dispersible polyurethane polymer, and a thermosetting or thermoplastic resinous latex in synergistic combination; and a pigment phase which includes corrosion-inhibiting pigment and, optionally, opacifying pigment.
