Abstract: The waterproofing and airtight pressure-sensitive adhesive tape is a pressure-sensitive adhesive tape containing a substrate having a pressure-sensitive adhesive layer on one side thereof, wherein the substrate is a rubber-made sheet; a film layer having non-self-adhesive properties and adhesive properties to the pressure-sensitive adhesive layer is formed on the substrate in the side opposite to the pressure-sensitive adhesive layer; and the waterproofing and airtight pressure-sensitive adhesive tape has an elongation at break (distance between two gage marks: 40 mm, drawing rate: 300 mm/min) of from 200 to 1,200% in both the longitudinal direction and the cross direction and a stress under 100% elongation (distance between two gage marks: 40 mm, drawing rate: 50 mm/min) of from 10 to 100 N/cm2 in both the longitudinal direction and the cross direction.

Abstract: A waterproof and airtight pressure-sensitive adhesive tape includes a substrate and a pressure-sensitive adhesive layer on one surface thereof, wherein the substrate is a rubber-made sheet; and a film-like material having elongation properties is laminated on a surface in the opposite side to the pressure-sensitive adhesive layer of the substrate. It is preferable that the rubber-made sheet as the substrate has an elongation at the time of breakage (distance between two gage marks: 40 mm, drawing rate: 300 mm/min) of from 200 to 1,200% in both the longitudinal direction and the cross direction and a stress under 100% elongation (distance between two gage marks: 40 mm, drawing rate: 50 mm/min) of from 10 to 100 N/cm2 in both the longitudinal direction and the cross direction.

Abstract: A waterproof and airtight double-sided pressure-sensitive adhesive tape includes a substrate and a pressure-sensitive adhesive layer on the both surfaces thereof, wherein the substrate is a rubber-made sheet; and the surface of at least one of the pressure-sensitive adhesive layers is protected by a release liner having elongation properties. It is preferable that the rubber-made sheet as the substrate has an elongation at the time of breakage (distance between two gage marks: 40 mm, drawing rate: 300 mm/min) of from 200 to 1,200% in both the longitudinal direction and the cross direction and a stress under 100% elongation (distance between two gage marks: 40 mm, drawing rate: 50 mm/min) of from 10 to 100 N/cm2 in both the longitudinal direction and the cross direction.

Abstract: A method for coating a metal surface by forming a corrosion-protective layer on the metal surface or a defective area of a corrosion-protective layer formed on the metal surface, which comprises using a coating material selected from the group consisting of a tape-like, sheet-like and chip-like polymerizable coating material comprising a vinyl monomer and/or a vinyl group-containing oligomer and a liquid material comprising a vinyl monomer and/or a vinyl group-containing oligomer, wherein either the coating material or the liquid material contains a polymerization initiator and the material not containing the polymerization initiator contains a polymerization accelerator, and polymerizing the vinyl monomer and/or the vinyl monomer-containing oligomer in the state such that the metal surface or the defective area is covered with the coating material by interposing the liquid material therebetween, to form the corrosion-protective layer.
