Is the final dry film thickness of the coating critical to its performance?
An average dry film thickness (DFT) of 15 to 20 mils (380 to 500 microns) of Si-COAT 570 HVIC is required for optimum product performance. If the final DFT is greater than 15 to 20 mils (380 to 500 microns), product performance is NOT reduced. It should be noted, however, that a greater thickness of coating will not lead directly to longer product life. Applying the coating in excessive thickness is merely a waste of material.
