Abstract: A treating agent comprises a nitrile group-containing highly saturated polymer rubber latex (A) having an iodine value of 120 or less, a rubber latex (B) other than the highly saturated polymer rubber latex, and a water-soluble resorcinol/formaldehyde condensate in amounts of 15 to 80%, 5 to 70% and 2 to 15%, all by weight in terms of solids, respectively. A rubber-reinforcing fiber product is coated with the treating agent. A rubber article such as a toothed belt, a tire and the like is made using this rubber-reinforcing fiber product. The glass fiber product coated with the treating agent may be further coated with a halogen-containing polymer-based adhesive as a secondary treating agent. Thus, the treating agent exhibits a large bonding force between the reinforcing fiber product and a matrix. Even if the rubber article is repeatedly subjected to a flexing stress, the strength thereof cannot be reduced. A peel-off cannot occurs between the reinforcing fiber product and the rubber matrix.

Abstract: A glass flake comprising a flake of glass having formed on its surface a metal covering layer on which is formed a dense protective covering layer of a metal oxide. The glass flake is produced by maintaining a flake of glass in an alkaline solution containing metal alkoxide, water and an alcohol, followed by the separation and firing thereof.

Abstract: A water-based treating liquid for a rubber-reinforcing glass fiber cord, which contains as a solid component a composition consisting essentially of;(1) a rubber latex(2) an alkylated chlorosulfonated polyethylene latex, and(3) a water-soluble resorcinol-formaldehyde condensate,wherein, based on the total amount of the components (1) and (2), the amount of the component (2) is 10 to 70% by weight and the amount of the component (3) is 5 to 20% by weight;a glass fiber cord for reinforcement of a rubber, which contains the above composition as a coating component; anda rubber product reinforced with the above glass fiber cord, the rubber product being excellent in fatigue resistance under heat and a flexing force.

Abstract: A liquid composition for glass fiber impregnation, characterized in that (A) it comprises (1) a resorcinol-formaldehyde resin, (2) a butadiene/styrene/vinylpyridine terpolymer, and (3) chlorosulfonated polyethylene, and (B) based on the total solids of the components (1), (2) and (3), the proportion of component (1) is 2 to 15% by weight, the proportion of component (2) is 15 to 80% by weight, and the proportion of component (3) is 15 to 70% by weight; and a glass fiber cord having a solid coating derived from the liquid composition. The glass fiber cord is useful as a reinforcing material in products, such as timing belts, which undergo both heat and an external force during travelling.
