摘要：The present disclosure is directed to a system for applying a waterborne coating composition to form a coating layer. The disclosure is particularly directed a system having dual water spraying devices for automatically introducing water into incoming air to produce a spray booth having a target range of humidity level. The system of this disclosure is particularly useful for applying a waterborne coating composition having effect pigments in a low humidity and high temperature climate.

主权项：1. A system for applying a waterborne coating composition over a substrate to form a coating layer, said system comprising: a spray booth for spraying the waterborne coating composition over the substrate, wherein the spray booth comprises one or more air inlets for introducing an incoming air or conditioned incoming air into the spray booth; and a water introduction device for introducing water into the incoming air, wherein the water introduction device comprises a first set of water spraying devices coupled to a first water supply device, a second set of water spraying devices coupled to a second water supply device, a water supply controlling device that controls water supply from the second water supply device to the second set of water spraying devices, and a water pump coupled to the first water supply device and the second water supply device; a first humidity measuring device for measuring a humidity level of air within the spray booth; wherein the water introduction device, when in operation, is configured to introduce water into the incoming air to produce the conditioned incoming air when the humidity level of air within the spray booth is below a target range of humidity level of the spray booth; and wherein the water introduction device is configured to have the water supply controlling device in an closed state so water is only introduced from the first set of water spraying devices into the incoming air when the humidity level of air within the spray booth is below the target range of humidity level but is above a preset first humidity level, and wherein the water introduction device is configured to have the water supply controlling device in an open state so water is introduced from both the first and the second set of water spraying devices into the incoming air when the humidity level of air within the spray booth is below the preset first humidity level.
