摘要:
Organic disulfonamides are accelerators for aerostable, anaerobically-setting adhesive compositions. They provide rapid setting of the adhesive with formation of bonds of good strength, and have little adverse effect upon the storage stability of the compositions when access of molecular oxygen is permitted.

Reaction products of glycidyl (meth)acrylate with linear half esters of dicarboxylic acids are components of anaerobically-setting adhesive compositions based on (meth)acrylic esters and organic peroxides.
摘要:
Organic percarboxylic acids are stabilizers for anaerobically-setting adhesive compositions wherein the principal adhesive component is a (meth) acrylic acid ester and the catalyst is an organic peroxide. The percarboxylic acid improves the storage-stability of the adhesives in contact with air.
摘要:
Organic nitrones are stabilizers for anaerobically-setting adhesive compositions wherein the principal adhesive component is a (meth) acrylic acid ester and the catalyst is an organic peroxide. The nitrone improves the storage-stability of the adhesives in contact with air.

摘要:
(Meth)acrylic acid esters of tricyclo [5.2.1.0..sup.2.6 ]-decane derivatives having the formula ##STR1## wherein A represents the radical ##STR2## wherein R is a divalent hydrocarbon having 2 to 6 carbon atoms selected from the group consisting of alkylene, alkenylene, cyclohexylene, phenylene and tetrahydrophenylene, and R.sub.1 is a member selected from the group consisting of hydrogen and methyl; as well as the process for the production of the esters, and their use in adhesive or sealing compositions which harden under exclusion of oxygen.

Reaction products of glycidyl (meth)acrylate with half esters containing carbonate groups are components of anaerobically-setting adhesive compositions based on (meth) acrylic esters and organic peroxides.
摘要:
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.
