Film hardness tinplate

The hardness of paint film on tinplate refers to the preparation of a paint film on tin-coated thin steel sheets, with the scratch resistance of the coating measured using the pencil hardness test method. The principle involves using a pencil of known hardness to scratch the paint film at a fixed angle and pressure, and determining the hardness grade based on whether scratches are produced. Its purpose is to quantify the mechanical strength of the coating, which is applied in quality control and process adjustments for coatings.
Selection
When selecting tinplate for paint film hardness testing, consider the substrate thickness and flatness, ensuring the tin coating is uniform and free of defects. Match the surface treatment process of the tinplate to the type of coating being tested, such as phosphating or passivation. The temperature and humidity of the testing environment must comply with standards, and sample dimensions should be cut according to the specifications of the testing instrument. Prioritize commercially available tinplate boards that meet the GB/T9271 standard.
