Seals
CHEMEON Surface Technology offers an array of vital seals, including TCP-HF and eTCP®, that significantly enhance the durability and performance of anodized aluminum surfaces. These seals, such as CHEMEON Seal 6000 (a nickel acetate-based option) and the trivalent chromium-based TCP-HF and eTCP®, close the porous anodic layer, boosting corrosion resistance and extending service life in harsh environments. TCP-HF and eTCP®, QPL-listed under MIL-PRF-8625, provide ambient temperature, non-carcinogenic alternatives to hexavalent chromium seals, delivering comparable protection with a safer, environmentally friendly profile. CHEMEON’s range of seals offer cost-effective, reliable solutions tailored to aerospace, automotive, and industrial needs, ensuring compliance with stringent standards while adding substantial value to the anodizing process.

FREQUENTLY ASKED QUESTIONS
What makes CHEMEON seals the highest quality for anodized parts?
Our formulations provide superior pore closure, corrosion resistance, and dye fixation with excellent consistency and minimal defects. Shops achieve longer-lasting, higher-quality finishes with fewer rejects.
Which sealing options does CHEMEON offer and when should I use each?
Hot water for maximum traditional performance; mid-temperature for energy efficiency and speed; nickel-free for compliance and environmental goals. Our team helps select the best fit for your alloys, dyes, and specifications.
How do CHEMEON seals work with conversion coatings and other chemistry?
They integrate seamlessly after anodizing and include our patented eTCP® and TCP-HF (Hex Free) as a trivalent anodic seal that replaces the known carcinogen hexavalent chrome, dilute chrome and sodium dichromate.
Does CHEMEON training cover sealing best practices?
Yes — our exclusive Aluminum Anodizing classes (offered a few times per year) include dedicated sealing modules on optimization, troubleshooting, and achieving consistent results.
Can I evaluate CHEMEON seals on my current production?
Absolutely. Request samples, technical support, or a comparative 3D metrology study to demonstrate improvements in corrosion performance and appearance.
What support is available for implementing CHEMEON seals?
: Full technical service, bath control guidance, compatibility testing, and ongoing optimization from our experts.
