Claim 2
Dependent Claim
76 words
An outside tire painting comprising a. at least one rubber latex, wherein said latex is selected from the group consisting of natural rubber latex and styrene butadiene latex, b. a wax dispersion containing paraffin wax, c. nonpelletized carbon block having a particle size greater than 50 millimicrons, d. water and e. surfactant, wherein said paint is substantially free of silicone and hydrocarbon solvents and has a solids content of from about 20 to about 30 percent.
Claim 3
Dependent Claim
11 words
A paint of claim 1 wherein a neutralizing agent is present.
Claim 4
Dependent Claim
11 words

Claim 5
Independent Claim
164 words
A method of producing an outside green tire paint which is substantially free of silicon and hydrocarbon solvents, said method comprising: (a) heating a wax to a temperature above the melting temperature of said wax, wherein the wax contains paraffin wax, (b) placing the wax under agitation, (c) adding a fatty acid and an amine to the molten wax, (d) adding a surfactant to the molten wax, (e) adding water wherein said water is preheated to a temperature greater than the melting point of said wax, (f) agitating the mixture while cooling to a temperature near ambient temperature to form a stable wax dispersion, (g) blending with said wax dispersion water, surfactant, nonpelletized carbon black having a particle size greater than 50 millimicrons, and a rubber latex, wherein said latex is selected from the group consisting of natural rubber latex and styrene butadiene latex, to form a stable outside green tire paint having a solids content of from about 20 to about 30 percent.
Claim 6
Independent Claim
164 words
A method of producing an outside green tire paint which is substantially free of silicon and hydrocarbon solvents, said method comprising: (a) heating a wax to a temperature above the melting temperature of said wax, wherein the wax contains paraffin wax, (b) placing the wax under agitation, (c) adding a fatty acid and an amine to the molten wax, (d) adding a surfactant to the molten wax, (e) adding water wherein said water is preheated to a temperature greater than the melting point of said wax, (f) agitating the mixture while cooling to a temperature near ambient temperature to form a stable wax dispersion, (g) blending with said wax dispersion water, surfactant, nonpelletized carbon black having a particle size greater than 50 millimicrons, and a rubber latex, wherein said latex is selected from the group consisting of natural rubber latex and styrene butadiene latex, to form a stable outside green tire paint having a solids content of from about 20 to about 30 percent.
Claim 7
Dependent Claim
15 words
