Claim 3
Dependent Claim
42 words
A traffic line paint according to claim 1 wherein the major portion of said pigments is selected from the group consisting of ground silica, natural clay, calcined clay and calcium sulfate having at least 50% of their particles finer than 5 microns.
Claim 4
Dependent Claim
16 words
A traffic line paint according to claim 2 wherein said low boiling solvent is methylene chloride.
Claim 5
Dependent Claim
31 words
A traffic line paint according to claim 3 wherein said resin binder is a glycerol phthalic alkyd having a glyceryl phthalate resin content of 40-58% and an oil content of 60-42%.
Claim 6
Dependent Claim
28 words
A traffic line paint according to claim 4 wherein said higher boiling solvent is an aliphatic hydrocarbon, 15% aromatic, IBP 250* F., EP 285* F. and KB 40.
Claim 7
Independent Claim
128 words
A method of applying a traffic line marker which is almost immediately dry upon deposition comprising pumping a traffic paint into a closed system under a fluid pressure of about 100-150 lbs./sq. inch, said traffic paint containing a resin binder, pigments, a higher boiling solvent, a pigment volume concentration from 46-62%, a solids content of 70-85% and from 7-23% of a low boiling solvent therein having a high solvency for the resin binder and a boiling range below the temperature at which the paint is to be sprayed, heating said paint to a temperature of about 140-250* F., releasing said heated paint through a spray orifice, applying auxiliary air pressure to said sprayed material immediately after leaving said orifice, and directing said sprayed stream onto a roadway surface.
Claim 8
Independent Claim
128 words
A method of applying a traffic line marker which is almost immediately dry upon deposition comprising pumping a traffic paint into a closed system under a fluid pressure of about 100-150 lbs./sq. inch, said traffic paint containing a resin binder, pigments, a higher boiling solvent, a pigment volume concentration from 46-62%, a solids content of 70-85% and from 7-23% of a low boiling solvent therein having a high solvency for the resin binder and a boiling range below the temperature at which the paint is to be sprayed, heating said paint to a temperature of about 140-250* F., releasing said heated paint through a spray orifice, applying auxiliary air pressure to said sprayed material immediately after leaving said orifice, and directing said sprayed stream onto a roadway surface.
Claim 9
Dependent Claim
22 words
