Pre-Treatment Chemicals

Pre-treatment chemicals are used for soaking, cleaning, removing compounds, and surface activation in almost all plating operations. The critical step(s) of pre-treatment of metal or other surfaces ensures finished products that produce the highest yields and reduce waste.

Ideal for the removal of buffing compounds, machine oils, cutting oils and shop soils. It is highly recommended for use in the processing of bumpers, furniture, or most any ferrous application. Unique surfactants and cleaning agents designed to lift and float most soils.
Enprep
373L
Removes a wide variety of oils, soils and greases from steel prior to any metal finishing operation. In many cases, it can act as a soak cleaner where limited cleaning is available. High alkaline product, slightly silicated non-chelated, non-phosphated, very low wetted. It quickly removes smuts, light rusts, weld and heat treat scale. Available in powder, liquid or liquid additive formulations.

Aluminum pre-treatment processes

Family
Products
Description
Alumon
101
Exceptional phosphated, non-silicated, non-etch, heavy duty production cleaner designed to remove a wide variety of oils, soils and inks from aluminum, aluminum alloys, copper and steel. When used as directed, will remove stubborn soils without causing downline incompatibility problems with subsequent etch, deoxidize, chemical polish or plating baths. Alkleen 101 provides a super fine micro-etch finish under elevated temperatures. Ideal for parts that cannot be heavily etched yet require additional “bite” to assure adhesion of subsequent coatings.
Alumon
108LF
Removes oil, dirt, chemical stains, rust, heat scale and oxides while simultaneously conditioning the metal surface in a single operation. Produces a surface that offers low surface resistance that is ideal for spot welding, while brightening and conditioning action make parts more receptive to conversion coatings, anodizing, painting and plating processes. On zinc die-cast, when used as an acid dip after cleaning, it is ideal in removing smuts.
Alumon
009L
Silicated, phosphated, non-etch, low foaming liquid soak cleaner that removes a wide variety of oils, soils and heavy buffing compounds from steel, aluminum, aluminum alloys, brass and zinc diecast. Has tremendous capacity for penetrating surface soils, with reserve power to keep cleaning for extended periods of time, lengthening time between bath changes. Easy to waste treat.
Endure
A Etch 185
“Blended powder, liquid or liquid additive (LA) materials, that contains caustic (except LA’s), sequestrates, extenders and builders, that is specifically designed to provide safe, uniform, consistent etching of aluminum and aluminum alloys. It provides the ultimate in etch technology. They produce varying depths of etch, from a light satin finish to deep stock removal, as in chemical milling. They etch at elevated concentrations of dissolved aluminum without having to dump or decant the etch bath. The will not cause dry-on stains or run down patterns even on large sheets and long transfer times. They are biodegradable products designed to produce little or no build-up on tank walls and heating coils.
Zincate
Bondal
Alloy zincte can be plated directly with Hickel
Endure
DOX NC-620
