In the Binks Gelmaster unit model 105-1138 the catalyst is mixed externally, i.e. catalyst is delivered by and trough the atomisation air and is then intimately mixed with the resin leading to a clear and air free sprayed gel coat film. The advantages are that no flushing is necessary and that the external catalyst delivery is clearly visible to the operator. This model is very suitable for multi-colored operation as a quick colour change is possible.
