摘要:
Water-borne reaction products of (a) carboxyl-functional polymers; (b) polyepoxides; and (c) tertiary amines are electrocoated to give desirable coatings. The coating compositions can be used with or without crosslinking agents and coalescing aids. The resulting coatings give improved properties, including high degree of flexibility during machining and stamping of the coated articles, corrosion resistance, gloss, hydrolytic stability, and are stable and nonadulterating in contact with foods and beverages.
摘要:
Heat sealable plastic films coated with a coating composition in the form of an aqueous dispersion containing specific copolymers in particulate form and which have good heat-sealing properties.
摘要:
An aqueous resinous dispersion and a method of coating employing the aqueous resinous dispersion are disclosed. The aqueous resinous dispersions are solubilized with base and comprise an acrylic polymer containing N-ethoxymethylacrylamide or methacrylamide moieties and an epoxy resin. The dispersion is useful for coating metal containers particularly as a coating for the interior of containers which are used for alcoholic beverages, for example, beer cans.
摘要:
Vinyl resins containing carboxyl or sulfonic acid functionalities can be formulated as stable, aqueous, colloidal dispersions suitable for preparing coatings by converting them to ionomers in a mixture of an organic solvent water-soluble organic polymer and water, followed by stripping off solvent.
摘要:
Insoluble microgel particles are added to solutions of polymerized ethylenically unsaturated monomers containing hydroxyl groups. The solutions may be spray coated onto various substrates in two coat applications to form coatings having improved gloss, film build and pattern control. The coatings are especially useful as automotive finishes.
