Abstract
Benzoylthiourea or benzoylthiourethane derivatives as cure accelerators for curable compositions are provided.
Claims11
An anaerobic curable composition, comprising:
- (a) a (meth)acrylate component;
- (b) an anaerobic cure-inducing composition comprising a peroxide and an anaerobic cure accelerator within structures I or IA below:
- wherein Z is O or N—R, where R is selected from hydrogen, alkyl, alkenyl, aryl, hydroxyalkyl, hydroxyalkenyl, alkylene(meth)acrylate, carbonyl, carboxyl, or sulfonato, and R′ taken together form a carbocyclic or hetero atom-containing ring, or R′ is a direct bond attaching to the phenyl ring;
- X is halogen, alkyl, alkenyl, cycloalkyl, hydroxyalkyl, hydroxyalkenyl, alkoxy, amino, alkylene- or alkenylene-ether, alkylene(meth)acrylate, carbonyl, carboxyl, nitroso, sulfonate, hydroxyl or haloalkyl;
- and Y is —SO2NH—, —CONH—, —NH—, and —PO(NHCONHCSNH2)NH—;
- and n is 0 or 1 and m is 1 or 2;
- wherein R and R′ are independently selected from hydrogen, alkyl, alkenyl, aryl, hydroxyalkyl, hydroxyalkenyl, alkylene(meth)acrylate, carbonyl, carboxyl, or sulfonato, or R and R′ taken together form a carbocyclic or hetero atom-containing ring, or R′ is a direct bond attaching to the phenyl ring;
- X is halogen, alkyl, alkenyl, cycloalkyl, hydroxyalkyl, hydroxyalkenyl, alkoxy, amino, alkylene- or alkenylene-ether, alkylene(meth)acrylate, carbonyl, carboxyl, nitroso, sulfonate, hydroxyl or haloalkyl;
- and Y is —SO2NH—, —CONH—, —NH—, and —PO(NHCONHCSNH2)NH—;
- and n is 0 or 1 and m is 1 or 2.

- and n is 0 or 1 and m is 1 or 2, or
- wherein R and R′ are independently selected from hydrogen, alkyl, alkenyl, aryl, hydroxyalkyl, hydroxyalkenyl, alkylene(meth)acrylate, carbonyl, carboxyl, or sulfonato, or R and R′ taken together form a carbocyclic or hetero atom-containing ring, or R′ is a direct bond attaching to the phenyl ring;
- X is halogen, alkyl, alkenyl, cycloalkyl, hydroxyalkyl, hydroxyalkenyl, alkoxy, amino, alkylene- or alkenylene-ether, alkylene(meth)acrylate, carbonyl, carboxyl, nitroso, sulfonate, hydroxyl or haloalkyl;
- and Y is —SO2NH—, —CONH—, —NH—, and —PO(NHCONHCSNH2)NH—;
- and n is 0 or 1 and m is 1 or 2.
