17 Claims

1. A two-component (2K) curable composition comprising:

(A) a first component comprising:

i) at least one cyanoacrylate monomer represented by Formula 1:

H₂C═C(CN)—COOR (1)

wherein: R is selected from C₁-C₁₈alkyl, C₃-C₁₈cycloalkyl, C₂-C₁₅alkenyl, C₆-C₁₈aryl, C₇-C₁₅aralkyl and C₃-C₁₅allyl; and,

ii) peroxide catalyst; and,

iii) at least one cure accelerator for said at least one cyanoacrylate monomer of (A)i);

(B) a second component comprising:

i) at least one free radically curable compound; and,

ii) at least one transition metal compound,

wherein, when said first and second components are mixed together, the peroxide catalyst initiates cure of said free radically curable compound and the transition metal compound(s) initiates cure of the cyanoacrylate monomer, and

wherein said at least one free radically curable compound comprises at least one unsaturated polyester polymer containing at least two cycloolefinic double bonds (UPS).
