Engineered specifically for post-anodizing and post-etching aluminum surface activation to remove residual smut, oxides, and process salts.
Non-chromated, low-VOC formulation compliant with RoHS 3 and REACH SVHC requirements.
Provides uniform matte finish and enhances paint adhesion without etching or dimensional change to the substrate.
Stable in hard water and compatible with automated spray and immersion cleaning systems.
Rapid rinseability—reduces drag-out loss and lowers wastewater treatment load.
Aerospace aluminum component finishing (e.g., structural brackets, housings).
Automotive trim and heat sink assemblies requiring high cosmetic consistency.
Architectural extrusions prior to powder coating or PVDF finishing.
Consumer electronics enclosures (laptop chassis, tablet frames) where micro-roughness control is critical.
Medical device housings requiring ISO 13485-aligned surface cleanliness validation.

Q1: What is the CAS Registry Number for SYS-9210?
A: SYS-9210 is a proprietary multi-component formulation; individual CAS numbers are not assigned to the blend. Full ingredient disclosure per TSCA and EU CLP Annex VII is available under NDA upon request.
Q2: What is the recommended working concentration and dwell time?
A: Dilute at 3–5% v/v in deionized water; typical dwell time is 60–120 seconds at 25–45°C. Optimal performance confirmed per ASTM B117 salt-spray testing after final rinse and drying.
Q3: How does SYS-9210 differ from traditional nitric-acid-based desmutters?
A: Unlike nitric acid desmutters, SYS-9210 eliminates NOx fume generation, avoids hydrogen embrittlement risk, and delivers consistent surface energy (measured via contact angle <72°) without micro-etching.
Q4: Is SYS-9210 validated for food-contact aluminum surfaces?
A: Yes—validated per FDA 21 CFR §175.105 for incidental food contact when applied per recommended parameters and thoroughly rinsed. Migration testing (EU 10/2011) shows <0.01 mg/kg for all target analytes.
