One of the main features of the Binks Gelmaster unit model 105-1138 is the externally mixed catalyst, 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-coloured operation as a quick colour change is possible. The unit includes spray gun, 20 litre pressure tank, air filtration, extractor and control components.
