Graph of adhesion plotted against the water content of railhead contaminants (% Solids) - note the danger zone of low adhesion occurs when there is a very small amount of water present.
Graph of adhesion plotted against the water content of railhead contaminants (% Solids) - by adding water, Water-Trak provides a step change in adhesion, taking conditions away from the danger zone.
