Anaerobically curable compositions

摘要

Dry-to-the-touch compositions containing a curable polymeric matrix and a curable anaerobic composition present within the polymeric matrix are disclosed. In a particularly desirable form, the compositions are moisture curable. The compositions are non-flowable at high temperatures and have an improved solvent resistance once cured.

主权项

1. A two part anaerobically curable composition, whose curable composition of a first part and a second part consists essentially of:
(a) a first part comprising:
(i) curable composition comprising:
(1) a diisocyanate and(2) optionally at least one material selected from the group consisting of a polyol, a polyamine, and a polythiol; and (b) a second part comprising:
(i) a curable composition comprising:
(1) an anaerobically curable material comprising a (meth)acrylate component;(2) an anaerobic cure system; and(3) at least one material selected from the group consisting of a polyol, polyamine, and a polythiol, wherein when mixed together an anaerobically curable composition is formed and a polymeric matrix is formed from the diisocyanate of the first part and the at least one material selected from the group consisting of a polyol, polyamine, and a polythiol of the second part and optionally of the first part through which is distributed the anaerobically curable composition.
