The Fospray: THREE‐STAGE ZINC PHOSPHATING SPRAY PROCESS Available to Purchase

The application of a phosphate coating prior to painting is accepted practice in most industries concerned with the manufacture of sheet steel products. Some firms employ the immersion process and others the spray application technique, the choice being governed largely by considerations of output, cost and floor space available. An important disadvantage of the latter process is the considerable length of tunnel required, this necessitating the occupation of valuable floor space that can often be ill spared. Recently we attended a demonstration of a new spray process which overcomes this drawback and, also, is said to possess certain other advantages over conventional installations.
