Passivation Chemicals and Application
We evaluate passivation solutions for post-galvanizing processes, leak testing, and inter-operational storage according to the requirements of the metal and the process.
Passivation Chemicals and Application
Passivation chemicals are used to support the post-treatment protection of metal surfaces and, in appropriate applications, pre-paint preparation. Product selection must be based on the metal type, existing coating, operating environment, and the targeted duration of protection.
As MFI Makina Kimya, we offer solutions for chromate or chromium-free passivation, post-galvanizing applications, and leak test baths. Application-specific products aimed at preventing corrosion during short-term inter-operational storage are also evaluated.
The suitability of nitrited and nitrite-free options is not determined solely by protection expectations. Bath conditions, subsequent manufacturing stages, and current technical and safety information of the product are considered together. Working concentration and operating methodology must be determined based on the selected product and the existing line.
Applications and Areas of Use
Passivation Options
The objective of passivation and the substrate to which it will be applied are decisive in selecting the correct chemical. We evaluate the existing coating, contact fluids, and subsequent processing requirements concurrently.
Our Application Process
We address every step collaboratively, from surface analysis to post-treatment inspection. The appropriate chemical and operating parameters are specified according to the component's intended application and your existing process.
Surface and Requirements Analysis
Metal type, existing coating, contact fluids, and targeted protection duration are evaluated.
Product and Method Selection
Chromate, chromium-free, nitrited, or nitrite-free options are assessed based on the application and downstream manufacturing steps.
Application and Bath Monitoring
The selected product is applied in accordance with technical specifications; concentration, contact time, and mandatory bath parameters are monitored.
Final Inspection and Protection
The surface condition is inspected; required drying, storage, and subsequent processing conditions are planned accordingly.
