Transferable, curable, non-liquid film on a release substrate

摘要

An article comprising a non-liquid curable transferable film, on a release substrate in which: a) the film is formed by a composition comprising: i) an elastomeric film-forming component, selected from the group consisting of copolymer elastomers ethylene acrylics, natural or synthetic rubbers, polyvinyl butyral resins and synthetic rubbers of chlorosulfonated polyethylene; and, ii) at least one curable component which is an electron deficient olefin component comprising a cyanoacrylate and which is selected from the group consisting of cyanoacrylic esters, methylidene malonate esters or cyanopentadionate esters and combinations thereof; or - an electron deficient olefin component comprising an ester component selected from the group consisting of propargyl, neopentyl, and adamantyl; or - an electron deficient olefin component comprising a diester; and combinations thereof, and b) said release substrate is a flexible vehicle, a flexible sheet or a flexible tape and is selected from the group consisting of paper, plastic, woven and non-woven substrates, which do not promote significant premature curing. of the curable component.
