Since 1975 the innovative and proven coating process of autodeposition has offered metal finishers world-wide the opportunity to enjoy a simpler, economic, and environmentally friendly finish for metal substrates.

An aqueous organic coating bath of Autophoretic^® 800 Series will efficiently and uniformly coat your metal parts without the complicated equipment requirements for anodes, rectifiers, or additional stages and floor space needed for phosphate conversion coatings.

Because the process in an Autophoretic^® 800 Series coating bath is driven chemically, rather than with electric current, deposition takes place wherever the solution wets a metal surface. Unlike most electrically driven coating processes, autodeposition can uniformly coat the inside and outside of tubular shapes, complex assemblies, and narrow crevices. A coating can form on metal surfaces wherever the aqueous solution can flow and be replenished.

The Autophoretic^® 800 Series coating reacts with the metal surface, so the need for additional phosphate conversion coating stages is eliminated. The metal surface requires only cleaning and rinsing equipment to prepare the part for the autodeposition stage. The chemical deposition rate of the Autophoretic^® 800 Series and the metal surface slows quickly as the film builds. This self limiting feature results in a uniform thickness for the entire part, even with machined areas and cut edges! Right off the line, your parts are ready to ship with no drips, sags, or runs.

The elimination of electric current results in energy savings. Because the racks do not have to be made of conductive materials, the frequency of rack stripping is greatly reduced. Additional energy savings and production load capacity are realized by the low bake-oven temperatures required for the Autophoretic^® 800 Series coating. The low pH environment of the coating bath discourages bacterial growth and the need for expensive and hazardous biocides. The absence of coalescing solvents in the Autophoretic^® 800 Series means fewer air pollution restrictions for your facility.

UNIQUE CHARACTERISTICS OF THE AUTODEPOSITION PROCESS

• Its ability to uniformly coat parts of all shapes, both inside and outside. "Wherever it wets. It coats."

• Its low temperature bake-oven requirements allow the processing of composite (rubber or plastic to metal) assemblies.

• No heavy metal final rinse is required to produce good corrosion resistance.

• Zero Volatile Organic Compounds means a reduction in air pollution problems

• The high chemical resistance of the dried film to oils, solvents, gasoline, and other materials.

• The exceptional physical properties of the dried film -- 6H pencil hardness, O-T flexibility, and 120-160 inch/lb. reverse impact.

• Higher film builds yield superior automotive underbody cyclic corrosion resistance and OEM approved specifications. Lower film builds offer unique wear resistance properties for sliding parts.

• The use of Lifeguard !on Exchange with the Autophoretic^® 800 Series coating yields competitive "first-time" transfer efficiencies and reduces solid waste.

• From start to finish, HST can support your companies global needs with equipment design engineering, pilot test facilities, customer training programs, and responsive field technical service to complement this unique technology.
