## Abstract

The present invention is directed to compositions for use as additives in the automotive industry, which compositions contain waste powder prime and a plasticizer selected from the group consisting of 2-ethylhexyl diphenyl phosphate, diisoheptyl phthalate, a linear phthalate based upon C.sub.7 -C.sub.9 alcohols, a mixture of esters containing a minimum of 55 percent of diesters and a maximum of 20 percent dibenzoate, a mixture of esters containing a minimum of 60 percent of diesters and a maximum of 30 percent dibenzoate and dipropylene glycol dibenzoate and automotive sealants which contain waste powder prime, a plasticizer selected from the group consisting of 2-ethylhexyl diphenyl phosphate, diisoheptyl phthalate, a linear phthalate based upon C.sub.7 -C.sub.9 alcohols, a mixture of esters containing a minimum of 55 percent of diesters and a maximum of 20 percent dibenzoate, a mixture of esters containing a minimum of 60 percent of diesters and a maximum of 30 percent dibenzoate and dipropylene glycol dibenzoate and automotive sealants; and a polymeric resin.

## Claims

### Claim 1

A composition, comprising:
waste powder prime; and
a plasticizer selected from the group consisting of 2-ethylhexyl diphenyl phosphate, diisoheptyl phthalate, a linear phthalate based upon C.sub.7 -C.sub.9 alcohols, a mixture of esters containing from about 50 to about 85 percent of 2-methyl-3-(benzoyloxy)-2,2,4-trimethylpentyl ester (CAS #22527-63-5), from about 10 to 30 percent of 2,2,3-trimethyl-1,3-pentanediol dibenzoate (CAS #68052-23-3) and from about 5 to about 10 percent of 2-methyl-2,2-dimethyl-1-(1-methylethyl)-1,3-propanediyl ester and dipropylene glycol dibenzoate, wherein the waste powder prime and the plasticizer are present in amounts effective to provide a viscosity-stable dispersion of the waste powder prime in the plasticizer.

### Claim 2 (depends on 1)

The composition of claim 1 wherein the waste powder prime and the plasticizer are present at a weight ration of about 1:10 to about 10:1.

### Claim 3 (depends on 1)

The composition of claim 1 wherein the plasticizer is selected from the group consisting of 2-ethylhexyl diphenyl phosphate, diisoheptyl phthalate, a linear phthalate based upon C.sub.7 -C.sub.9 alcohols, and dipropylene glycol dibenzoate.

### Claim 4 (depends on 1)

The composition of claim 1 wherein the plasticizer is selected from the group consisting of 2-ethylhexyl diphenyl phosphate and diisoheptyl phthalate.

### Claim 5 (depends on 1)

The composition of claim 1 further comprising a polymeric resin of the type used to prepare conventional automotive sealants, in amounts effective to provide film-forming properties to the automotive sealant.

### Claim 6 (depends on 5)

The composition of claim 5 comprising from about 0.1 to about 50 percent of the waste powder prime, from about 0.1 to about 50 percent of the plasticizer and from about 10 to about 50 percent of the polymeric resin.

### Claim 7 (depends on 6)

The composition of claim 6 wherein the polymeric resin is selected from the group consisting of poly(vinyl chloride), poly(vinyl acetate), copolymers of vinyl chloride and copolymers of vinyl acetate.

### Claim 8 (depends on 1)

The composition of claim 1 further comprising a component selected from the group consisting of an adhesion promoter, a filler, a solvent and a rheology modifier, in amounts effective to perform the specific function for which the component is used.

### Claim 9 (depends on 1)

The composition of claim 1 wherein said composition is free of adhesion promoters.
