Designed specifically for aircraft exterior touch-ups, CAMMDA's Paint Pax™ is a complete self contained system that stores, mixes and applies two-component paints and primers. Each Paint Pax™ kit consists of a pre-filled two component cartridge, an applicator gun and a mixer. The cartridge keeps the reactive materials separated until ready to use. The materials do not meet until they enter the disposable mixer, thereby providing an environmentally friendly, solvent-free mixing solution. Paint Pax™ offers significant advantages over spray based touch-up methods by decreasing costs, decreasing waste, increasing productivity and reducing environmental impact.
