Standard Regulations For Adhesion Fastness To Non-stick Pans

1. Immerse the sample in boiling water and cook for 15 minutes, take it out, cool it down to room temperature naturally and dry it with a soft cloth.

2. Use the tip of a sharp single-sided blade and a steel ruler or a special grid template to score 11 parallel scratches with a distance of 2.4mm and a length of 38mm on the coating, and then repeat the above steps along the direction perpendicular to the scratches. The tip must penetrate the coating to the metal.

3. Adhere to the scratched area with a single-sided transparent pressure-sensitive adhesive tape, and the direction of the tape is parallel to a set of scratched lines. Firmly rub the tape with your fingernail to dislodge air from the tape bond and allow for maximum adhesion to the coating.

4. Hold one end of the tape with your fingers, and quickly pull it up at a right angle of 90°, 3 times in a row, each time you need to use a new tape.

5. Rotate the scratch 90° and repeat steps 3 and 4 with a new tape.

After the test, the coating does not fall off in the cross-cut area. This test is mainly to prevent the coating from peeling off, thereby affecting the non-stick effect.
