Air Quality Data
Volatile Organic Compounds (VOC):
- Part A as packaged, maximum 2.85 lb/gal, 342 g/L
- V93V230 as packaged, maximum 2.63 lb/gal, 316 g/L
- catalyzed as above, maximum 2.8 lb/gal, 340 g/L
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.
