Abstract:
For obtaining a substrate on the surface of which a water repellent film is firmly bonded through an undercoating film, and which shows a low critical inclination angle, superior durability, and high density, a water repellent and/or oil repellent film layer is formed by using a liquid for undercoating treatment. The liquid for undercoating treatment is obtained by dissolving and reacting a material having chlorosilyl radicle radicle in molecular form therein and is dissolved into an alcohol group solvent, so that a surface roughness (Ra) of less than 0.5 nm is obtained, thereby achieving high durability and a low critical inclination angle.
Abstract:
A method of depositing a functional group on a surface portion of an elastic substrate comprises the steps of: (a) stretching an elastic substrate having an initial surface portion to form an enlarged surface portion from the initial surface portion; then (b) conjugating a functional group on the enlarged surface portion; and then (c) releasing the substrate to form a reduced surface portion from the enlarged surface portion, with the reduced surface portion having an area less than the enlarged surface portion, and with the reduced surface portion having the functional group deposited therein at a greater density than the enlarged surface portion.
Abstract:
Continuous coatings are prepared using novel two part compositions and methods. The two part compositions of the invention comprise, in separate containers, a powder polymer composition and a coalescing agent. The powder composition has preferred particle size distribution and composition for use in the compositions or methods of the invention. The coalescing agents of the invention cooperate with the powder part to result in a excellent finish having the appropriate drying hardness, durability, etc. The novel method of the invention involves contacting a coalescing agent with polymer particles in a variety of coating methods. The particles and the coalescing agent interact to form a continuous coating layer or finish layer. The basic coating formation methods of the invention can be embodied in a number of methods or protocols including applying a solid polymer to the liquid coalescing agent, applying the agent to the polymer particulate or applying the liquid and polymer simultaneously. In any protocol, a desirable floor finish can be easily formed. This invention is particularly suitable for a floor finish composition.
Abstract:
A method is provided for producing a thin film product, comprising a first step in which an underlying substrate of a first material is provided. The underlying substrate includes a plurality of unmodified sites. The underlying substrate is then chemically modified wherein a plurality of organic functional groups are attached to a plurality of the unmodified sites. The arrangement and type of the functional group used can be selected for the purpose of controlling particular properties of the second material deposited. A thin film layer of at least one second material is then deposited onto the chemically modified underlying substrate. This can be accomplished by connecting the thin film to the underlying substrate by binding the thin film to the functional groups.
Abstract:
The present invention relates to a method for preventing fogging or clouding of surfaces comprising glass, high molecular weight substance, and the like. The method comprises the steps of: (1) applying a dispersion liquid wherein a high molecular substance having a hydroxyl group is added to the surface to be treated (2) causing the substance on the surface to react while adding cyanuric chloride, (3) hydrolyzing the resultant mixture with a base, (4) neutralizing the treated surface, (5) rinsing and drying the above neutralized surface, (6) reacting a nonionic surface active agent having a fluorine group or a silicone group with a NH.sub.2 group or H group to react on the surface, (7) hydrolyzing the resultant surface and then, (8) neutralizing the surface with an acid.

This invention relates to improvements in and relating to curing of surface coatings and has been devised particularly though not solely for the curing of surface coatings such as paints or inks.
Abstract:
Aqueous compositions containing as essential ingredients; an alkanolamine, an aliphatic carboxylic acid containing 5 to 18 carbon atoms, and an arylenetriazole have been found effective in removing resin-containing sealants from the surfaces of zinc containing metals, such as galvanized steel, without causing changes in the surfaces of the metal, so that phosphate coatings which are subsequently applied to said surfaces are neither streaky nor spotty.
Abstract:
Highly sensitive positive electron beam resists comprised of copolymers of methacrylic acid (MAA) and t-butyl methacrylate (TBM) are disclosed in which a thin film of high molecular weight MAA/TBM copolymer is applied to a suitable substrate. Prior to exposure, the copolymer is prebaked at a temperature below the decomposition temperature to improve the sensitivity and resolution of the resist. The exposed resist is developed by spraying with a suitable solvent. The positive electron resists produced in accordance with the present invention exhibit a high sensitivity and good submicron resolution.
Abstract:
A coating composition consisting essentially of certain heat-stable polymers, colorants, antioxidant, and liquid carrier useful for coating an article to produce a finish which is capable of maintaining its hue and can have a decorative pattern produced within it. The antioxidant is phosphoric acid which has been neutralized with an excess of ammonia or an organic base, preferably a volatile amine, to give a pH in the coating composition of at least about 8.5.
Abstract:
A method of increasing the corrosion resistance of enamel coated steel by the application of a silyation agent in an effective amount to prevent the corrosion of enamel coated steel products is disclosed. This invention is particularly suited for the prevention of the interaction of a canned food product with its container.
