SURFACE-PROMOTED CURE OF ONE-PART RADICALLY CURABLE COMPOSITIONS
First Claim
1. A radically curable composition for curing on a surface comprising:
- i) a radically curable component;
ii) a free radical generating component; and
iii) at least one metal salt;
wherein the standard reduction potential of the at least one metal salt is greater than the standard reduction potential of the surface, andwherein when the composition is placed in contact with the surface, the metal salt is reduced at the surface, and interacts with the free radical generating component, thereby initiating cure of the radically curable component of the composition.

Abstract
The present invention relates to radically curable compositions for curing on a surface comprising a radically curable component, and an initiator component capable of initiating cure of the radically curable component. The initiator comprises at least one metal salt and a free radical generating component. The metal salt of the composition is chosen so that it is reduced at the surface, where the standard reduction potential of the metal salt is greater than the standard reduction potential of the surface, and where when the composition is placed in contact with the surface, the metal salt is reduced at the surface, and interacts with the free radical generating component, thereby initiating cure of the radically curable component of the composition. No catalytic component is required in the composition for efficient curing.

-
(i) applying a composition comprising; i) a radically curable component; ii) a free radical generating component; and iii) at least one metal salt; to at least one of the substrates; and (ii) mating the first and second substrates so as to form a bond with the composition, where the standard reduction potential of the at least one metal salt is greater than the standard reduction potential of at least one of the substrates. - View Dependent Claims (19, 20)
