Performance of PLD-5 Series Ceramic Coatings
Polima ceramic coatings have high hardness, rich colors, excellent corrosion resistance, and temperature resistance. They meet the requirements for non-stick coatings on both the interior and exterior of household kitchenware, as well as outdoor weather resistance and energy-saving environmental protection. Kitchen utensils: frying pans, stir-fry pans, air fryers, and bread molds. Electrical appliances: baking trays, frying pans, irons.
| Test Item | Test Method | Test Result |
| Pencil Hardness Test | Using a hardness tester, apply a force of 1.0±0.05kg at a 45-degree angle to the coated surface, at a speed of 0.5mm/s on the coating surface. Pull back 3mm after coating, repeat 5 times. |
≥8H |
| Abrasion Test | Using an abrasion tester, 3M 7447B scouring pad, load 1.5KG, 5% detergent solution. Perform back and forth. Wear test. |
≥20000 cycles |
| Non-stick Test | Pour one egg onto the coating surface heated to 160-180℃, after frying, use a spatula to check if it sticks to the coating surface. Repeat 300 times. |
Pass |
| High Temperature Resistance Test | Place the sample in an oven at 400℃ for continuous heating for 10,000 hours; the coating color must not show obvious changes. | No discoloration |
| Salt Water Resistance Test | Make “×” cuts at the bottom and sides of the inner pot, add 5% salt water up to the highest water level, boil for 8 hours as one cycle. After 4 cycles, no blistering, stains, or other defects should appear on the cuts or coating surface. |
>6 cycles |
| Acid Resistance Test | Inject 5% acetic acid solution into the sample up to the maximum scale, boil and maintain for 30 minutes, then leave for 24 hours. The coating should show no obvious discoloration, blistering, corrosion spots, peeling, or other abnormalities. |
