Abstract: A method for coating steel structures in water which comprisescoating as a first layer an underwater-curable composition comprising(1) a two-pack resin blend system comprising(a) a blend system comprising an epoxy-based resin, and(b) a blend system comprising an underwater-curable curing agent capable of hardening the epoxy-based resin blend system, and(2) from 5 to 75% by weight, based on the total weight of the underwater-curable composition, of a metal powder having an ionization tendency greater than that of iron,on the steel structures, andcoating an underwater-curable composition comprising the two-pack resin blend system and a coloring pigment on the first layer as a second layer.

Abstract: An epoxy resin coating composition comprising a rubber-modified epoxy resin which is obtained by reacting an epoxy resin with a carboxyl group-containing butadiene-acrylonitrile rubber, a phenoxy resin, a metal powder, a curing component, and an organic solvent. This composition is especially useful as a coating for fuel tanks particularly, gasohol fuel tanks. The cured coating from the composition has excellent properties of heat resistance, chemical resistance, corrosion resistance, flexibility and weldability.

Abstract: A thermosetting adhesive sheet is described, comprising a thermosetting resin sheet-shaped prepreg with a reinforcing material embedded therein, and a flattened tubular material provided on one side of the prepeg, said flattened tubular material being capable of nearly recovering the original tubular form on heating and being narrower in width than the prepreg. The prepreg may be of the two-layer structure comprising a first thermosetting resin composition layer and a second thermosetting resin composition layer.

Abstract: A material for reinforcing a panel or plate includes a first resin layer having a high tensile modulus of elasticity after hardening; a second resin layer having a low tensile modulus of elasticity after hardening; an expandable member disposed between the second resin layer side and the panel to be reinforced. The expandable member is narrower than the reinforcing resin sheet. The first and second resin layers are combined in an unhardened or semi-hardened state to form a reinforcing resin sheet. The expandable member expands into a bead-like projection when heated and then hardens. The edges of the reinforcing resin sheet extend beyond the edges of the bead-forming member or expandable member is such a manner that the second resin layer of the reinforcing resin sheet can be attached to the panel or plate.

Abstract: An adhesive-sheet for the reinforcement of metal plate, and a method of reinforcing metal plates using an adhesive-sheet, are described. The adhesive-sheet comprises a first epoxy resin composition layer and a second epoxy resin composition layer laminated thereon wherein the first epoxy resin composition layer, when cured by heating, has a modulus of elasticity in tension sufficient to increase the stiffness of the metal plate, whereas the second epoxy resin composition layer, when cured by heating, has a modulus of elasticity in tension insufficient to increase the stiffness of the metal plate.
