BONDERITE® 2798™ Process for High Aluminum

A novel, patented phosphating process is applied to cold rolled and zinc clad steels, while leaving aluminum surfaces substantially uncoated. In a subsequent in-line step, the aluminum is zirconium coated. The process provides the optimum pretreatment for each of the substrates, while reducing sludge generation by up to two-thirds. This FLEX process accommodates a wide variety of aluminum content vehicles with the total aluminum surface area ranging up to 85%.
