Abstract
An anaerobically curable composition comprising: a liquid anaerobically curable component; a solid anaerobically curable component; a solid polyether polyvinyl butyral resin; and a curing component for curing the anaerobically curable components. Advantageously, the compositions of the invention are substantially solid and may be used as threadlockers.
Claims25
An anaerobically curable composition comprising:
- a liquid anaerobically curable component;
- a solid anaerobically curable component;
- a solid thermoplastic polyvinyl butyral resin;
- and
- a curing component.
2 more elements
A method for manufacturing a tape, thread, or fibre for threadlocking comprising the steps of:
- (i) mixing at least one solid thermoplastic polyvinyl butyral resin;
- wherein the molecular weight Mw is as determined in accordance with ASTM D5296-05, and solvent;
- (ii) mixing therewith:
- a liquid anaerobically curable component, a solid anaerobically curable component and a curing component;
- so as to form an anaerobically curable composition;
- (iii) forming the mixture into a desired form;
- removing the solvent and/or allowing the solvent to evaporate, to thereby form a tape, thread, or fibre comprising the anaerobically curable composition.
