Abstract
Abstract A self-emulsifying anaerobic-curing composition is disclosed. The composition is rendered self-emulsifying by incorporating certain anionic and/or nonionic surfactants in a concentration range of about 0.25 to about 10.0 percent. The preferred anionics comprise the petroleum sulfonates and the sodium alkyl or alkylaryl sulfonates. The preferred nonionics comprise the ethoxylated alkyl alcohols, the ethoxylated alkyl phenols, and the polyoxyethylene/polyoxypropylene glycols. Any anaerobic monomer or monomer mixture in which the surfactant is soluble and compatible with the cure system may be used. These self-emulsifiable compositions have the advantage of being readily removed from surfaces by washing with water, which makes them especially useful in impregnation processes where uncured resin must be removed from areas which are difficult to wash, such as small, blind holes.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
71 words
An anaerobic curing composition which is self-emulsifiable upon mixing with water comprising: a. an anaerobically curing acrylate monomer; b. a peroxy initiator in sufficient concentration to initiate cure of the monomer upon exclusion of oxygen; and c. about 0.25 to about 10.0 percent by weight of the total composition of an anionic or nonionic surfactant which is dissolved in the composition and which renders the composition self-emulsifying upon mixing with water.
Claim 2
Dependent Claim
71 words
An anaerobic curing composition which is self-emulsifiable upon mixing with water comprising: a. an anaerobically curing acrylate monomer; b. a peroxy initiator in sufficient concentration to initiate cure of the monomer upon exclusion of oxygen; and c. about 0.25 to about 10.0 percent by weight of the total composition of an anionic or nonionic surfactant which is dissolved in the composition and which renders the composition self-emulsifying upon mixing with water.
