Abstract:
An aerobically curable adhesive composition, comprising the product of combininga) a first component comprisingi) at least one polyurethane (meth)acrylate having a boiling point above 120.degree. C. at normal pressure;ii) optionally, at least one additional (meth)acrylate comonomer other than a polyurethane (meth)acrylate provided said additional (meth)acrylate comonomer has a boiling point above 120.degree. C. at normal pressure;iii) at least one free radical initiator; andiv) at least one transition metal-free accelerator; andb) a second component comprisingi) at least one polyurethane (meth)acrylate having a boiling point above 120.degree. C. at normal pressure;ii) optionally, at least one additional (meth)acrylate comonomer other than a polyurethane (meth)acrylate provided said additional (meth)acrylate comonomer has a boiling point above 120.degree. C. at normal pressure;iii) a drier comprising at least one soluble metal salt of an organic acid having a metal component selected from the group consisting of Co, Fe, Zr, Mn, Ce, Pb, Zn, Ca, Ba, Y and combinations thereof; andiv) optionally, a transition metal accelerator selected from the group consisting of salts and complexes of copper, vanadium and nickel;subject to the proviso that if only one soluble metal salt of an organic acid is utilized in said drier (iii), the transition metal accelerator (iv) is also utilized in the second component and wherein within 30 days of combining said first component and said second component a surface of the adhesive composition in contact with air is no longer tacky.
