A spray application device that can apply the coating material without stringing (non-stringing) in its original liquid form.
A spray application device that allows for the application of undiluted coating material without causing stringing phenomena.
When using a solvent-based adhesive material with a high molecular weight at a high concentration, the coating liquid that comes out of the nozzle at the tip of the spray gun does not become mist-like but instead takes on a thread-like appearance (stringiness). The causes include insufficient dissolving power of the diluent thinner in the coating liquid and a rapid evaporation rate of the solvent after spraying. This phenomenon is particularly likely to occur when the nozzle diameter of the spray gun is small. The spray application device developed this time provides a spray application system that is less prone to stringiness and clogging, even when using high-viscosity liquid coating materials such as concentrated solutions. This spray application device consists of a spray gun equipped with an outlet that atomizes the liquid coating material and a generator that supplies solvent mist fog air. (Patent pending) This application device sprays the coating material discharged from the spray gun using solvent mist fog air, which atomizes the coating material during the process. Therefore, even when using a high-viscosity concentrated solution as the liquid coating material, the mist fog air of this device can prevent the occurrence of stringiness in advance.
