Pre-treatment Requirements
Steel Surfaces
Ensure that steel surfaces are clean and free from grease before coating. Pretreatment is essential for achieving maximum protection.
Ferrous Metals
Iron phosphate or zinc phosphate pretreatment can improve the corrosion resistance of ferrous metal components.
Aluminum Parts
The original technical guidance specifies chromate conversion pretreatment for aluminum components. Confirm the appropriate pretreatment system for the substrate and applicable environmental requirements.
Application Guidelines
Spray Equipment
MT-A2204 basecoat powder can be applied using manual or automatic electrostatic spray equipment. Tribo application is not recommended.
Powder Fluidization
Fluidize the powder during application to help achieve consistent coverage and appearance.
Curing and Clearcoat
Fully cure the basecoat before applying the clearcoat. Incomplete curing may affect the metallic effect or cause clearcoat discoloration. Apply the clearcoat as soon as possible, with a maximum interval of 8 hours between coats.
Oven Compatibility
The original application guidance states that the referenced metallic powder is not stabilized for direct gas-fired ovens. Confirm oven compatibility with the supplier before use.
Handling and Process Precautions
Clean Handling
Handle all coated components with clean, lint-free gloves.
Humidity Control
Avoid storing coated components in high-humidity environments.
Before Clearcoat Application
Do not pass basecoated parts through another pretreatment process before applying the clearcoat.
Powder Recovery
Recycling the metallic powder is not recommended, even though the metallic effect is bonded.
