Abstract

The present invention relates to lubricious anaerobic curable compositions.

Claims (20)

1. A lubricious anaerobic curable composition, consisting essentially of:

(a) a (meth) acrylate component;

(b) an anaerobic cure-inducing composition; comprising saccharin and toluidine; and

(c) a particulate lubricious agent comprising the combination of graphite having a particle size of less than 325 mesh and polyethylene; and

(d) optionally, one or more additives selected from the group consisting of free radical initiators, free radical accelerators, free radical inhibitors, metal catalysts, thickeners, plasticizers, fillers, and toughening agents.

2. The composition according to claim 1 , wherein the (meth)acrylate component is represented by H 2 C═CGCO 2 R 1 , wherein G is a member selected from the group consisting of H, halogen and alkyl having from 1 to about four carbon atoms, and R 1 is a member selected from the group consisting of alkyl, cycloalkyl, aklenyl, cycloalkenyl, alkaryl, and aryl groups having from 1 to about 16 carbon atoms, with or without substitution or interruption by a member selected from the group consisting of silane, silicon, oxygen, halogen, carbonyl, hydroxyl, ester, carboxylic acid, urea, urethane, carbamate, amine, amide, sulfur, sulfonate and sulfone.

3. The composition according to claim 1 , wherein the (meth)acrylate component is a member selected from the group consisting of silicone (meth)acrylates, polyethylene glycol di(meth)acrylates, bisphenol-A-(meth)acrylates, alkoxylated bisphenol-A-(meth)acrylates, bisphenol-F-(meth)acrylates, ethoxylated bisphenol-F-(meth)acrylates, tetrahydrofuran (meth)acrylates and di(meth)acrylates, hydroxypropyl (meth)acrylate, hexanediol di(meth)acrylate, and trimethylol propane tri(meth)acrylate.

4. Cured reaction products of the composition according to claim 1 .

5. A process for preparing a reaction product from an anaerobic curable composition, comprising the steps of:

apply an anaerobic curable composition according to claim 1 , to a desired substrate surface and

exposing the composition to an anaerobic environment for a time sufficient to cure the composition.

6. A method of preparing a lubricious anaerobic curable composition in accordance with claim 1 , comprising the step of:

mixing together:

a (meth)acrylate component,

an anaerobic cure inducing composition and

a lubricious agent.

7. A composition comprising a bond formed between two mated substrates with the composition of claim 1 .

8. The composition according to claim 1 , where each of graphite and polyethylene are present in a range of 5-30% by weight.

9. The composition according to claim 1 , combination of graphite and polyethylene in a by weight ratio of about 1:1.

10. The composition according to claim 1 , wherein the graphite has a specific gravity between 0.62-2.71.
