We have a bunch of experience in spray and atomization - we have a aerosol filling line and have product in aerosol cans ranging from solvents to heavy grease. The things that influence patterns are pressure, orifice size/shape, viscosity, base material, delivery gas (propane, butane, heptane, CO2...) and carrier solvent/diluent for starters. Thats a several dependent variables to monkey with. That actually provides a bunch of opportunity to get it done. I think you may have to go with a very smal orifice(s) and use higher pressure.
