Abstract
Organic hydrazones (compounds which contain the =N--N=C= structure) are accelerators for aerostable anaerobically-setting adhesive compositions. They can be used with stabilizers. Preferred hydrazones are acetophenone hydrazone, methyl ethyl ketone hydrazone, methyl isobutyl ketone hydrazone. These provide rapid setting times with good ultimate strength, and have little adverse effect upon the storage stability of the compositions when access of molecular oxygen is permitted. Diacetyl hydrazone provides best ultimate strength.
