Abstract
Dry-to-the-touch compositions containing a polymeric matrix and a anaerobically curable component 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.
Claims26
A dry-to-the-touch curable composition comprising:
- a polymeric matrix comprising a material selected from the group consisting of a polyurethane, a polyurea, a polysulfonamide, a polythiourethane and combinations thereof;
- and
- an anaerobically curable component dispersed within said polymeric matrix, wherein said polymeric matrix is present in amounts of about 30% to about 80% by weight of the composition, and the composition remains non-flowable at temperatures greater than 260° C. up to about 300° C.
A composition comprising:
- a matrix comprising:
- (a) the polymeric reaction product of:
- a polyisocyanate reactant and at least one compound selected from the group consisting of:
- (i) an alcohol;
- (ii) an amine;
- (iii) a thiol;
- (iv) sulfonamide;
- and
- (b) an anaerobically curable composition distributed within said matrix.
The matrix of claim 13, wherein the polyisocyanate is polyamine polyisocyanate.
A product comprising:
- a carrier substrate;
- and
- a coating on said substrate comprising:
- a polymeric matrix comprising a material selected from a group consisting of a polyurethane, a polyurea, a polysulfonamide, a polythiourethane and combinations thereof;
- and an anaerobically curable component present within said matrix.
An article of manufacture comprising:
- a threaded member at least partially coated with a dry-to-the-touch composition comprising a polymeric matrix selected from the group consisting of a polyurethane, a polyurea, a polythiourethane and combinations thereof and having an anaerobically curable component distributed therein.
An article of manufacture comprising a preformed gasket comprising a dry-to-the-touch polymer matrix having an anaerobically curable component distributed therein.
A method of preparing an article of manufacture comprising:
- (a) providing a threaded member;
- (b) at least partially coating said threaded member with a dry-to-the-touch polymeric matrix having an anaerobically curable component distributed therein.
A method of assembling threaded parts comprising:
- (a) providing a first threaded member;
- (b) providing a second threaded member capable of matingly engaging said first threaded member;
- at least one of said first and second threaded members being at least partially coated with a dry-to-the-touch composition comprising a polymeric matrix and a anaerobically curable component distributed therein;
- (c) matingly engaging said first and second threaded parts and permitting the composition to anaerobically cure therebetween.
