Product Name：
Aluminum Surface Oxide Treatment Agent
Scope of Application：
Engineered to eliminate tenacious oxidation residues and chemical conversion films that remain after alkaline etching, acid pickling or mechanical/chemical polishing of aluminum alloys.
Operating Instructions：
1. Prepare a 5–10 % v/v solution in clean water at ambient temperature (15–35 °C).
2. Immerse the aluminum parts in the treatment bath; agitate by work-piece movement, air sparging or ultrasonic agitation for 30 s–3 min.
3. Rinse thoroughly with de-ionized or running water to remove all loose residues; proceed to downstream conversion coating or drying.

Performance Advantages
Aluminum Surface Oxide Treatment Agent
1. Rapid Oxide Removal – High-reaction-rate chemistry dissolves stubborn aluminum oxides and conversion residues within 30 seconds to 3 minutes, cutting process time and raising throughput.
2. Non-Etching, Gloss-Preserving – Balanced, inhibitor-enhanced formula selectively attacks oxides while leaving the base aluminum unaffected; maintains original reflectivity and dimensional tolerance, eliminating re-work or bright-dip steps.
3. EU-Compliant, Eco-Safe – Free of chromates, nitrites, PFOA/PFOS and SVHC-listed substances; fully aligned with REACH, RoHS and WFD directives for worry-free global shipment and workplace safety.
4. Ambient, Hassle-Free Operation – Works effectively at 15–35 °C without heating, power-consuming baths or complex controllers; simple dip-spray-ultrasonic compatibility reduces labor, energy and equipment costs.
Safety Precautions
– Wear solvent-resistant gloves and eye protection; avoid prolonged skin contact.
– If product contacts eyes, rinse cautiously with plenty of running water for ≥15 minutes, remove contact lenses if present, then seek immediate medical attention.
Packaging & Storage
25 kg net in HDPE tight-head drum. Store sealed in a cool, dry, well-ventilated area away from direct sunlight and frost.
Shelf Life
36 months from manufacture date in original, unopened container.
Friendly Reminder: For maximum bath life and operator safety, always contain this aluminum oxide remover in a chemical-grade PP tank or other corrosion-resistant plastic (PVC, HDPE, PVDF). Metal vessels will leach ions and shorten reagent stability.
Aluminum Surface Oxide Treatment Agent
Purpose-built for low-silicon aluminum alloys after alkaline etching, chemical polishing or electro-polishing. 1. Dual Action: simultaneously strips tenacious oxide films and removes residual drawing oils, smuts and polishing compounds in a single step. 2. Ultra-Low Attack: <0.3 µm metal loss on Al≤1 % Si alloys—preserves critical dimensions and mirror-bright finish. 3. Bright, Water-Break-Free Surface: leaves a uniformly clean, chemically active substrate that enhances adhesion and coverage of subsequent conversion coatings, anodize or plating baths. 4. Bath Life Extension: powerful wetting agents lift particulate soils into solution, reducing drag-out and prolonging the life of downstream desmut, anodizing or chromate-free passivation tanks.
