Bonderite M-FE 687 (was Novaphos F687) imparts a corrosion-resistant coating which greatly improves paint adhesion onto surfaces of iron, steel, aluminium, or zinc components. A formulated iron phosphate solution, it includes a fluoride element within the matrix to permit the phosphating of mixed metals. Bonderite M-FE 687 is supplied as a heavy colourless liquid for spray application. It may be applied in multistage spray wash or spray tunnel systems and will tolerate light soiling on the part being treated. On its own Bonderite M-FE 687 will clean and phosphate in one operation, while the addition of a Bonderite C-AD detergent will significantly enhance the cleaning action. Bonderite M-FE 687 is supplied in highly concentrated form and is typically diluted at the rate of seven litres per 1000 litres, or 0.7% by volume. It may be applied at a range of temperatures from 30-60C at moderate pressure of 1.5-2.0 bar. Contact time is just 1.5-3.0 minutes, to leave a clean phosphated surface offering good corrosion protection and excellent paint adherence. Bonderite M-FE 687 is classified as non-hazardous and conforms to BS3189 Type 4 and DEF STAN 03-11 Class IV specifications.
