  • Process for spraying one-component compositions with air-assisted, low pressure equipment having an improved spray nozzle
    Patent number: 6764026
    Abstract: The present invention relates to a process for spraying a one-component composition by a) activating the trigger mechanism of a caulking gun having two or more rams and containing two or more cartridges to incrementally advance a ram into operative engagement with each cartridge and dispense a first liquid binder component from a first cartridge and a second liquid additive component from a second cartridge into a static mixer having an optionally removable spray tip, b) mixing the first component and the second component in the static mixer, c) discharging the mixed liquid components from the static mixer through the optionally removable spray tip at the downstream end of the static mixer into an atomizing zone, d) introducing air into the atomizing zone, e) atomizing the mixed liquid components in the atomizing zone, f) spraying the atomized liquid components onto a substrate and g) during an interruption in the spraying process or after termination of the spraying process, discarding the static mixe

  • Spray nozzle for a two-component air-assisted, low pressure spray system
    Patent number: 6695224
    Abstract: The present invention relates to a spray nozzle for a two-component, air-assisted, low pressure spray system including 1) a static mixer having an upstream end and a downstream end wherein a) the upstream end has an inlet port for receiving a first liquid component and a second liquid component that is reactive with the first liquid component and the upstream end is dimensioned to be reversibly connected to a dispensing unit for the first and second liquid components, 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 2) 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 has outlet por

  • 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.

  • Spray nozzle for two-component air-assisted, low pressure spray systems
    Patent number: 6616068
    Abstract: The present invention relates to a spray nozzle for a two-component, air-assisted, low pressure spray system including a) a static mixer having an inlet port on its upstream end for receiving a first liquid component and a second liquid component that is reactive with the first liquid component and having on its downstream end an optionally removable spray tip for introducing the mixed liquid components into an atomizing zone, b) a static mixer shroud, which encases the static mixer, is dimensioned on its upstream end for connecting the shroud to a dispensing unit for the first and second liquid components and has on its downstream end an optionally removable 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.
