  • Air-assisted, low pressure spray equipment having an improved spray nozzle
    Patent number: 6672519
    Abstract: Air-assisted, low pressure spray equipment having an improved spray nozzle including a caulking gun having a carriage adapted to receive cartridges having a nozzle, rams mounted on the caulking gun for engaging each cartridge to dispense a liquid from the nozzle, a trigger mechanism for advancing the rams into operative engagement with each cartridge; a static mixer having an inlet port for receiving a liquid component from the nozzle of each cartridge and having an optional spray tip for introducing the mixed liquid components into an atomizing zone; a static mixer shroud encasing the static mixer and an optional spray section having inlet ports for receiving pressurized air and outlet ports for introducing air into the atomizing zone. The spray tip passes through an orifice in the spray section such that the mixed liquid components are introduced into the atomizing zone. The equipment is useful for spraying a two-component composition.

  • Air-assisted, low pressure spray equipment having an improved spray nozzle
    Patent number: 6572031
    Abstract: The present invention relates to air-assisted, low pressure spray equipment having an improved spray nozzle including 1) a caulking gun having a carriage adapted to receive two or more cartridges having a nozzle, 2) a static mixer having an upstream end and a downstream end wherein a) the upstream end has an inlet port for receiving a liquid component from the nozzle of each cartridge and the upstream end is dimensioned to be reversibly connected to the cartridges of the caulking gun, and b) the downstream end has an optionally removable spray tip for introducing the mixed liquid components into an atomizing zone and the downstream end is dimensioned for reversibly connecting the static mixer to a spray section, and 3) a spray section having an upstream end and a downstream end wherein a) the upstream end of the spray section is dimensioned for being reversibly connecting to the static mixer, b) the spray section has inlet ports for receiving pressurized air and c) the downstream end of the spray section h
