GlasCraft's INDy Dispense Gun was specially designed for use with non-atomizing nozzles. Achieving a complete, uniform mix of catalyst and resin at very low operating pressures common with non-atomizing nozzles can be a challenge. Virtually any gun can be fitted with a non-atomizing nozzle, BUT ONLY THE INDy was specially designed, tested, and documented to deliver outstanding performance with these new non-atomizing dispense nozzles. Forget the rest, go with the best - Go with GlasCraft!
