Dry film thickness (DFT)


Every coating has its own specifications set by the coating manufacturer. Cookware manufacturers have to follow these specifications and the DFT must be controlled and written down after the final application. Sometimes it is difficult to measure the DFT directly on the substrates during the production, like in case of cast aluminium, stainless steel and hard base substrates. Under these circumstances DFT measurements must be carried out on “smooth” aluminium panels in order to have a value as close as possible to the real one. As a “rule of thumb”: the higher the DFT the more durable the coating.
