Performance test
Abrasion resistance
Test method: Use an abrasion tester with a 500g load and 3M 7447B scouring pad (simulating a spatula/steel wool), and record the number of friction cycles.
Qualification Requirements: High-quality coatings must withstand ≥10,000 rubs without exposing the substrate, and after rubbing, the fried egg test should show no significant sticking.
Adhesion test
Test method: Cross-cut test – Use a blade to cut a 1×1mm grid, then observe the area of peeling after removing 3M tape; or perform a bending test (180° bend).
Qualification Requirements: Cross-cut adhesion test area ≤5% (ISO 2409 grade 0/1), no cracking or peeling after bending.
Thermal shock resistance
Test method: Thermal shock test – after maintaining a high temperature of 250℃, rapidly cool to -20℃, repeating the cycle 50-100 times.
Qualification Requirements: The coating has no cracks, blisters, or peeling.
Chemical resistance
Test method: Soak test: Soak in 4% acetic acid (simulating vinegar), 3% sodium carbonate (simulating alkali), and ethanol (simulating oil) at 80°C for 6 hours..
Qualification Requirements: The coating shows no corrosion, discoloration, or softening.
Non-stick test
Test method: Fried egg test (observe the degree of sticking after frying an egg without oil) or boiled water test (water droplets form beads and roll, contact angle ≥ 90°).
Qualification Requirements: Residue on ingredients ≤0.1g/dm², easy-to-clean rating ≥8/10.
Safety inspection
Heavy metal migration
Test method: ICP-MS testing – after soaking in 4% acetic acid, measure the content of lead, cadmium, arsenic, etc.
Qualification Requirements: Lead/Cadmium ≤ 0.01 mg/dm², Arsenic/Mercury not detected.
Total migration
Test method: Simulated liquid immersion – boil in 4% acetic acid (acidic) or 95% ethanol (oily) for 0.5 hours, then let stand at room temperature for 24 hours, and measure the total amount of dissolved substances.
Qualification Requirements: ≤10 mg/dm² (total of all non-volatile substances).
Perfluorinated compounds (PFAS)
Test method: GC-MS/LC-MS Testing – For PTFE coatings, screening for prohibited substances such as PFOA and PFOS.
Qualification Requirements: Must not be detected (EU REACH requirement ≤0.01 μg/dm²).
Volatile organic compounds (VOCs)
Test method: Headspace GC testing – measures the content of volatile substances in coatings.
Qualification Requirements: ≤50 μg/g (to avoid odor or harmful gas release).
