Provided is a conductive material dispersion comprising single-walled carbon nanotubes, a dispersant, a dispersion aid, and a dispersion medium, wherein the dispersant comprises polyvinyl butyral and hydrogenated nitrile butadiene rubber, and the dispersion aid comprises a compound represented by Formula 1.

A-(R).sub.n  [Formula 1]

In Formula 1, A is a structure having a carbon number of 16 to 50 carbon number and comprising four or more aromatic rings and nitrogen, R is a structure comprising an anionic functional group, and n is an integer of 1 to 5.

A multi-layered multifunctional polymeric latex article is provided. A first polymeric latex layer, having nitrile butadiene, is resistant to chemical permeation whilst the second polymeric latex layer disposed on the first layer, being a composite layer of polychloroprene and Nano clay, is resistant to chemical degradation. The third layer disposed on the second layer is a polychloroprene layer having a unique micro-roughened surface texture pattern, providing an improved grip and friction in both wet and dry conditions. The second and third layers are disposed during the wet gelled stages of the first and second layers respectively. The gelled third layer is dipped in a solvent mixture whereby a chemical reaction causes the gelled surface of the third layer to texturize by swelling and fixing, creating a continuous and discontinuous wavy micro-roughened surface which is then cured causing formation of ionic crosslinks in the third polymeric layer.

A coating agent for oil seal comprising 10 to 90 parts by weight in total of fluororesin particles having a particle size of 2 μm or less and filler particles other than fluororesin particles having a particle size of 0.5 to 30 μm, and 10 to 40 parts by weight of a wax having a melting point of 40 to 160° C., based on 100 parts by weight of isocyanate group-containing 1,2-polybutadiene, and being prepared as an organic solvent solution, wherein the fluororesin particles are used at a ratio of 20 to 80 wt. % of the total filler amount. The coating agent for oil seal can improve abrasion resistance while maintaining the roughness of a coating surface to which the coating agent is applied.

Room temperature-vulcanizing silane-containing resin compositions are described, containing: (A) 100 parts by mass of a silane-modified polybutadiene compound represented by formula (1) ##STR00001##
(B) 0.5 to 20 parts by mass of a hydrolyzable organosilane compound having in each molecule an average of at least two silicon atom-bonded hydrolyzable groups, and/or the partial hydrolysis condensate of this hydrolyzable organosilane compound; and (C) 0.1 to 10 parts by mass of a curing catalyst. This room temperature-vulcanizing silane-containing resin composition is suitable for application as a coating agent composition and in particular as, e.g., a coating agent for electrical and electronic components and substrates therefor, and a sealant for liquid crystal display elements. The room temperature-vulcanizing silane-containing resin composition provides a gas permeation-resistant coating film (cured material) and is useful as a coating agent that exhibits a corrosion-inhibiting capability versus corrosive gases.
