Abstract:
Air-assisted, low pressure spray equipment having an improved spray nozzle comprisinga) a caulking gun having a carriage adapted to receive two or more cartridges having a nozzle, two or more rams mounted on the caulking gun for operatively engaging each cartridge to dispense a liquid component from the nozzle of the cartridge, a trigger mechanism for manually, pneumatically, hydraulically or electrically advancing the rams incrementally into operative engagement with each cartridge, b) a static mixer having an inlet port on its upstream end for receiving a liquid component from the nozzle of each cartridge and having on its downstream end an optionally removable spray tip for introducing the mixed liquid components into an atomizing zone, c) a static mixer shroud, which encases the static mixer, is dimensioned on its upstream end for connecting the shroud to the cartridges of the caulking gun and has on its downstream end an optional spray section having inlet ports for receiving pressurized air and outlet ports for introducing air into the atomizing zone, wherein the spray tip passes through an orifice in the spray section such that the mixed liquid components are introduced into the atomizing zone.
