How does Vallejo Airbrush Flow Improver work?

Flow improver is a liquid compound that is designed to be used with an airbrush. Most modellers will thin their paints prior to using an airbrush, this helps with overall paint consistency giving the optimal painted surface on a model. One issue that can develop is that of paint drying too quickly. An airbrush uses air pressure to atomise paint to deliver optimal flow and produce a professional finish. Unfortunately, due to the small size of the droplets, the paint can sometimes dry on the airbrush needle leading to poor flow and clogging of the airbrush.

Flow improver gets around this problem by containing a drying retardant that helps to delay the drying time. When properly mixed with the paint this helps to ensure a good flow from the airbrush and avoids paint drying prematurely on the needle and subsequent clogging. This will help ensure that more time is spent painting rather than cleaning the airbrush and removing paint blockages. A ratio of 2:10 Flow Improver to paint is an ideal mix guaranteed to improve paint flow, especially when using thinned paint or the smallest sized needles.
