These anaerobic cure accelerators are generally sulfinimides and oxygen and sulfur derivatives thereof, sulfonimides and oxygen and sulfur derivatives thereof, sulfonamides and oxygen and sulfur derivatives thereof, and oxygen and sulfur analogues of sulfimides.
Claims13
An anaerobic curable composition, comprising:
- (a) a (meth)acrylate component;
- (b) an anaerobic cure-inducing composition substantially free of saccharin;
- and
- (c) an anaerobic cure accelerator compound within structure I
- wherein Y is an aromatic ring, optionally substituted at up to five positions by C1-6 alkyl or alkoxy, or halo groups;
- A is C═O, S═O or O═S═O;
- X is NH, O or S and Z is an aromatic ring, optionally substituted at up to five positions by C1-6 alkyl or alkoxy, or halo groups, or Y and Z taken together may join to taken together may join to the same aromatic ring or aromatic ring system, provided that when X is NH, o-benzoic sulfimide is excluded from structure I.
