Aluminum Substrate Preparation

	Cleaners
Product Powder Liquid Complexor Phosphate Silicate Emulsifying Displacement Features/Benefits Soak Clean ENPREP® 35 Ideal for mild, non-etch cleaning of aluminum. Because no silicates are present in the cleaner, no residual siliceous films remain to cause non-uniform anodized or conversion coatings. ENPREP® INFINITY Aqueous, biological cleaning system that consumes and eliminates oils and soils. Oils and soils are converted into inert organic material, carbon dioxide and water. The cleaner is continuously regenerated to maintain optimum cleaning efficiency. Surfactants are biodegradable. Etch ACTANE® E-10 Acidic etch is especially effective for difficult to plate alloys. Ideal for applications where minimal dimensional changes and maximum reflectivity are required. ENPREP® 14 Non-scaling alkaline cleaner produces a fine, uniform etch that ensures pristine surfaces for subsequent plating operations. ENPREP® 167 Heavy etch produces fine, uniform etch.
