Chromating Application and Chemicals
We evaluate chromating and chrome-free passivation solutions that support corrosion resistance and pre-paint preparation on aluminum surfaces in line with your process requirements.
Chromating Application and Chemicals
Chromating is a chemical conversion process applied to aluminum surfaces for protection and pre-paint preparation. The resulting layer is evaluated in conjunction with the operating environment of the surface and the subsequent coating system.
As MFI Makina Kimya, we evaluate yellow chromate, green chromate, and chrome-free passivation options based on aluminum alloy, surface condition, targeted performance, and existing line conditions. Chemical selection should not be based solely on coating color.
The application begins with degreasing and removing other contaminants from the surface. Pre-treatment, rinsing, immersion or spray conditions, and post-treatment steps are planned according to the product's current technical data. Chemical composition, equipment compatibility, and waste management must be evaluated on a product-specific basis.
Application and Evaluation Areas
Coating Options and Process Control
Yellow and green chromate applications alongside chrome-free passivation possess distinct product and process characteristics. In determining the appropriate choice, we address surface preparation, paint system, and bath control collectively.
Our Application Process
We evaluate all steps collectively, from the inspection of the aluminum surface to post-treatment control. The product and operating parameters are tailored to the component's intended use and your existing line setup.
Alloy and Needs Analysis
The aluminum alloy, current surface condition, operating environment, and targeted paint or protection requirements are evaluated.
Surface Preparation
Degreasing, contaminant removal, necessary pre-treatments, and rinses are planned according to the alloy and the selected product.
Coating Application
Immersion or spray application is performed using the appropriate chemical; contact time and bath parameters are monitored in accordance with technical data.
Post-Treatment and Inspection
Required rinsing and drying steps are evaluated; the surface is inspected for suitability regarding the subsequent painting or operational stage.
