Aluminum: Clean with acidic cleaner or other appropriate cleaner depending on contamination. Pretreat with chromate conversion coating MIL-DTL-5541F, wash primer DOD-P-15328D, E90G4, or anodize per MIL-A-8625F.
Testing: Due to the wide variety of substrates, surface preparation methods, application methods, and environments, the customer should test the complete system for adhesion and compatibility prior to full scale application.
- This product must be properly mixed (catalyzed) before using.
- Surface preparation is important for performance.
- For good adhesion, parts primed need to air dry a minimum of 2 hours before topcoating. If parts have been primed for longer than three days, they must be sanded or recoated with a mist coat before topcoating for good adhesion.
- These primers contain strontium chromate.
