Graco Inc. recently launched its HydroShield Waterborne System. It says the new finishing system gives manufacturers more reason to switch from conventional to electrostatic technology to spray waterborne material. The HydroShield batch system, the first installment of a developing product line, gives operators the control to use Pro Xp WB air spray and air-assist electrostatic spray guns to spray waterborne material. The batch isolation system benefits industrial finishing operations by allowing refill without system shutdown so when the painter releases the spray gun trigger, the internal isolation pump refills itself from a supply source, improving productivity. Other features, such as an automatic refill, reduces the need to open the isolation cabinet, resulting in greater safety, Graco says. The controller interface allows users to select spray functions, stay informed of system status and set a maintenance schedule. Graco says using electrostatics to spray waterborne material means more paint lands on each part, compared to conventional spraying. “We designed the HydroShield system with the operator in mind,” says Wendy Hartley, Graco Product Marketing Manager for the Industrial Products Division. “The controller keeps the operator informed of the system status and provides process control, which makes spraying high-quality parts easy.”
