Process for spraying one-component compositions with air-assisted, low pressure equipment having an improved spray nozzle

摘要: The present invention relates to a process for spraying one-component composition by a) activating the trigger mechanism of caulking gun having two or more rams and containing cartridges incrementally advance ram into operative engagement with each cartridge dispense first liquid binder component from second additive static mixer which is encased in shroud has an optionally removable spray tip, b) mixing mixer, c) discharging mixed components through tip at downstream end atomizing zone, d) introducing air e) f) atomized onto substrate g) during interruption after termination process, discarding tip.
