Abstract: A method of producing an opaque adherent coating on the surface of a substantially hydrated cementitious substrate is provided. A waterborne storage stable sealer comprising an aqueous medium containing a binder polymer and an opacifying polymer is applied on the surface of such a cementitious substrate.

Abstract: This invention concerns a process for imparting corrosion and creep resistance to a coating prepared from a particulate polymer composition and applied from a fluidized bed or by electrostatic spraying over metal substrates. The process of the present invention provides for maintaining the content of acid functionality of an acid-functionalized semicrystalline or acid-functionalized amorphous particulate polymer of the particulate polymer composition within a desired range. The acid functionality on the particulate polymer can be maintained, by crosslinking and/or neutralizing, within a desired range of the acid content which results in imparting corrosion and creep resistance to the coating applied over the metal substrates. Neutralizing the acid functionality of the polymer component results in hardening the coatings resulting therefrom. The process further provides for adding anticorrosive pigments to the composition for further improving corrosion resistance of the resultant coatings.

Abstract: The present invention is directed to producing a luminescent screen used in a cathode ray tube (CRT) suitable for monochromatic or chromatic images, such as, those utilized in televisions, computers or data monitoring equipment, which require CRTs. The method of the present invention produces an ablative layer of the luminescent screen having a smooth surface with reduced surface distortions, such as, streaks and waviness, which are typically produced by conventional coating processes. When a reflective aluminum film is deposited on such a smooth ablative layer, the reflective aluminum film is also provided with a smooth surface, since it typically conforms to the underlying smooth surface of the ablative layer. As a result, CRT images having reduced distortions are produced.
