Abstract
Phenylhydrazine/anhydride adducts and anaerobic curable compositions using these adducts are provided. The compositions are particularly useful as adhesives and sealants.
Claims10
An anaerobic curable composition, comprising:
- (a) a (meth)acrylate component;
- (b) an anaerobic cure-inducing composition and (c) a compound of Structure I
- wherein:
- R1 is selected from the group consisting of H and C1-4 alkyl;
- p is an integer between 1 and 5;
- and
- the cycloaliphatic ring represents a cycloalkyl, cycloalkenyl, bicycloalkyl or bicycloalkenyl, with or without one or more C1-4 alkyl substituents.
4 more elements
A method of preparing an anaerobic curable composition, comprising the step of:
- mixing together:
- i) as an anaerobic cure accelerator, a compound having Structure I
- wherein:
- R1 is selected from the group consisting of H and C1-4 alkyl;
- p is an integer between 1 and 5;
- and
- the cycloaliphatic ring represents a cycloalkyl, cycloalkenyl, bicycloalkyl or bicycloalkenyl, with or without one or more C1-4 alkyl substituents;
- (ii) a (meth)acrylate component;
- and
- (iii) an anaerobic cure-inducing composition.
7 more elements
A method of using a compound of Structure I
- wherein:
- R1 is selected from the group consisting of H and C1-4 alkyl;
- p is an integer between 1 and 5;
- and
- the cycloaliphatic ring represents a cycloalkyl, cycloalkenyl, bicycloalkyl or bicycloalkenyl, with or without one or more C1-4 alkyl substituents, as an anaerobic cure accelerator comprising the step of either:
- (I) mixing the compound with a (meth)acrylate component, an anaerobic cure inducing composition, or (II) applying onto a surface of a substrate the compound and applying thereover an anaerobic curable composition.
