## Abstract

The present invention relates to primer compositions in non-flowable form. More particularly, the present invention relates to non-flowable primer compositions which are particularly useful for use with curable adhesive and sealant compositions in threadlocking, retaining, bonding and sealing applications and which can be packaged in a convenient pocket-sized applicator dispenser.

## Claims

### Claim 1

A primer composition comprising:
a. at least one primer compound, which can activate polymerization of a polymerizable composition; and
b. a polymeric matrix selected from the group consisting of urea-urethanes, hydroxy or amine-modified aliphatic hydrocarbons, polyester-amide-based rheological additives and combinations thereof, and present in an amount sufficient to render said primer composition non-flowable at temperatures up to about 160° F. (71° C.) and wherein said primer composition is dispensable at room temperature without application of heat.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

The composition of claim 1, further comprising a polymerizable compound.

### Claim 5 (depends on 4)

The composition of claim 4, wherein said polymerizable compound is a mono-functional (meth)acrylate.

### Claim 6 (depends on 1)

The composition of claim 1, wherein the polymeric matrix is present in amounts of about 5% to about 15% by weight of the composition.

### Claim 7 (depends on 1)

The composition of claim 1, wherein the polymeric matrix is present in amounts of about 7% to about 10% by weight of the composition.

### Claim 8 (depends on 1)

The composition of claim 1, in combination with a polymerizable composition is selected from the group consisting of anaerobic compounds, epoxy compounds, acrylic compounds, polyurethane compounds, olefinic compounds, silicon compounds, and combinations thereof.

### Claim 9 (depends on 1)

The composition of claim 1, wherein said polymeric matrix further includes a material selected from the group consisting of polyamides, polyacrylamides, polyimides, and polyhydroxyalkylacrylates.

### Claim 10 (depends on 1)

The composition of claim 1, further including fumed silica.

### Claim 11 (depends on 1)

The composition of claim 1 wherein said primer compound is a compound or complex selected from the group consisting of the transition metals copper, cobalt and iron.

### Claim 12

An article of manufacture comprising:
a. a dispensing container for housing and dispensing a non-flowable adhesive or sealant composition, said container comprising a generally elongate hollow body having first and second ends, with one of said ends defining a dispense opening;
b. a primer composition within said container, said composition comprising:
(i) at least one primer compound; and
(ii) a polymeric matrix selected from the group consisting of urea-urethanes, hydroxy or amine-modified aliphatic hydrocarbons, polyester-amide-based rheological additives and combinations thereof, and present in an amount sufficient to render said primer composition non-flowable at temperatures up to about 160° F. (71° C.) and wherein said primer composition is dispensable at room temperature without application of heat.

### Claim 13 (depends on 12)

The article of manufacture of claim 12, wherein said polymeric matrix further includes polyamides, polyacrylamides, polyimides, and polyhydroxyalkylacrylates.

### Claim 14 (depends on 1)

A kit comprising:
a. a primer composition in accordance with claim 1;
b. a polymerizable composition.
