Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
A method of producing an inside green tire paint which is substantially free of silicone and hydrocarbon solvents, said method comprising (a) heating more than one wax to a temperature above the melting point of the highest melting point wax, (b) adding an amine and a fatty acid to the molten wax, (c) adding a surfactant to the molten wax, (d) adding water which has been preheated to a temperature greater than the melting point of the highest melting point wax, (e) agitating the mixture while cooling to a temperature below the melting point temperature of the lowest melting point wax to form a wax dispersion, (f) blending a rubber latex, water and surfactant with said wax dispersion, and (g) adding a pigment capable of functioning as an air bleeding agent.
Claim 2
Independent Claim
