Aluminum Pretreatment Chemistries for Production Finishing
Cleaners, etchants, deoxidizers, desmutters, anodizing additives, dyes, sealants, and service tools engineered for aluminum finishing, anodizing, painting, chromating, and plating operations.
Better aluminum finishing starts before anodizing, painting, or plating.
Aluminum surfaces often require cleaning, etching, deoxidizing, desmutting, and sealing before consistent finishing performance can be achieved.
Ronatec aluminum chemistries are designed to remove soils, oils, oxides, smut, heat scale, and surface contamination while preparing aluminum alloys for downstream processes.
From non-etch cleaners and controlled etchants to aerospace-ready deoxidizers, anodizing dyes, seals, and service tools, Ronatec helps finishers improve surface preparation, appearance, and production consistency.
Process chemistry designed for cleaner surfaces, better adhesion, and consistent finish quality.
Cleaner Surfaces
Remove oils, soils, buffing compounds, oxides, and surface contaminants before finishing.
Controlled Etching
Support uniform, consistent etching from light satin finishes to deeper stock removal.
Deoxidizing & Desmutting
Prepare aluminum surfaces prior to anodizing, bright dipping, plating, painting, and chromating.
Anodizing Support
Service tools, sealants, fume suppressants, additives, and dyes for anodizing operations.
Sealing
Ronatec offers a range of sealing technologies, including cold seals, mid-temperature seals, traditional high-temperature seals, and advanced sealing products designed to penetrate the anodized pores for enhanced corrosion protection while helping control smut.
Aerospace Alignment
Ronatec aluminum products support current aerospace, military, ASTM, Boeing, Airbus, and MIL requirements.
Complete process chemistry from cleaning through coloring and sealing.
Ronatec supports the aluminum finishing sequence with chemistry for cleaning, etching, deoxidizing, anodizing support, coloring, sealing, and finish enhancement.
Remove oils, soils, grease, ink, and buffing compounds.
Create controlled surface texture and prepare the aluminum substrate.
Remove oxides and smut before anodizing or finishing.
Apply anodizing dyes for required color, appearance, and application performance.
Support anodic coating performance, appearance, and long-term durability.
Cleaner 108LF
Cleaner 108LF removes oil, dirt, chemical stains, rust, heat scale, and oxides while simultaneously conditioning the metal surface in a single operation. It produces a surface that offers low surface resistance ideal for spot welding, while helping make parts more receptive to conversion coatings, anodizing, painting, and plating processes.

Aluminum pretreatment chemistry questions.
What is aluminum pretreatment?
Aluminum pretreatment is the cleaning, etching, deoxidizing, desmutting, and surface preparation process used before anodizing, chromating, painting, plating, or conversion coating.
What is an aluminum deoxidizer?
An aluminum deoxidizer removes oxides and smut from aluminum surfaces before downstream finishing processes such as anodizing, bright dipping, plating, painting, chromating, or chemical polishing.
Why etch aluminum before anodizing?
Etching helps create a uniform surface condition and can produce finishes ranging from light satin appearance to deeper stock removal depending on time, temperature, concentration, and process requirements.
What is aluminum sealing?
Sealing is used after anodizing to improve the performance and durability of anodic coatings. Ronaseal MTS is a mid-temperature nickel-based seal designed for anodized aluminum. Ronatec offers a variety of sealing options, from effective cold seal processes to state-of-the-art mid-temp seals and traditional high-temp seals and service products which provide better corrosion protection by getting deeper into the anodized surface pores while controlling smut.
Does Ronatec supply aluminum anodizing dyes?
Yes. Ronatec supplies a broad range of anodizing dyes, including RoHS- and REACH-compliant options, dyes supporting MIL-A-8625 Type II Class 2 requirements, colors matching many Pantone colors, and dyes for outdoor applications.
Does Ronatec support hardcoat anodizing?
Yes. Ronatec offers a liquid additive for higher temperature Type III anodizing that allows hardcoat operation at 60°F while helping improve film thickness uniformity.
