Abstract

The present invention relates to cyanoacrylate compositions in non-flowable and gel forms. More particularly, the present invention relates to non-flowable cyanoacrylate compositions which can be packaged in a convenient pocket-sized applicator dispenser for use in spreading the cyanoacrylate compositions onto substrates.

First claim

What is claimed is:

1. A room temperature non-flowable, one part cyanoacrylate adhesive composition comprising:
a. at least one α-cyanoacrylate compound; and
b. a polymeric material selected from the group consisting of hydroxyl-modified aliphatic hydrocarbons, polyester-based rheological additives and combinations thereof, present in an amount sufficient to render said compositions non-flowable at temperatures up to about 180° F.

2. The composition of claim 1 , wherein said composition is dispensable at room temperature without application of heat.

3. The composition of claim 1 , wherein said polymeric material is present in an amount sufficient to render said composition non-flowable at temperatures up to about 80° F.

4. The composition of claim 1 , wherein said hydroxyl modified aliphatic hydrocarbons include hydroxyl modified glycerides of 12-hydroxystearic acid.

5. The composition of claim 1 , wherein said polyester-based rheological additives include reaction product compositions of polycarboxylic acid, alkoxylated polyols and a monocarboxylic acid having aliphatic unsaturation.

6. The composition of claim 1 , wherein the α-cyanoacrylate is represented by compounds of the formula:

wherein R 1 represents a straight chain or branched chain substituted or unsubstituted alkyl group having 1 to 12 carbon atoms, a straight chain or branched chain substituted or unsubstituted alkenyl group having 2 to 12 carbon atoms, a straight chain or branched chain substituted or unsubstituted alkynyl group having 2 to 12 carbon atoms, a substituted or unsubstituted cycloalkyl group, an substituted or unsubstituted aralkyl group or a substituted or unsubstituted aryl group.

7. The composition of claim 5 , wherein R 1 is selected from the group consisting of a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, an isobutyl group, a pentyl group, a hexyl group, an allyl group, a methallyl group, a crotyl group, a propargyl group, a cyclohexyl group, a benzyl group, a phenyl group, a cresyl group, a 2-choroethyl group, a 3-choropropyl group, a 2-chorobutyl group, a trifluoroethyl group, a 2-methoxyethyl group, a 3-methoxybutyl group, a 2-ethoxyethyl group and combinations thereof.

8. The composition of claim 1 , wherein said α-cyanoacrylate is an ethyl cyanoacrylate monomer.

9. The composition of claim 1 , wherein said α-cyanoacrylate compound is present up to about 90% by weight of the total composition.

10. The composition of claim 1 , wherein the polymeric matrix is present in amounts of about 5% to about 30% by weight of the composition.

11. The composition of claim 1 , further comprising an anionic polymerization inhibitor.

12. The composition of claim 1 , further comprising a radical polymerization inhibitor.

13. The composition of claim 1 , further comprising polyhydroxyalkylacrylates.

14. A room temperature non-flowable, one part cyanoacrylate adhesive composition consisting essentially of:
a. at least one α-cyanoacrylate compound; and
b. a polymeric material selected from the group consisting essentially of hydroxyl-modified aliphatic hydrocarbons, polyester-based rheological additives and combinations thereof, present in an amount sufficient to render said compositions non-flowable at temperatures up to about 180° F.
