Introduction: The cupping device is designed and manufactured according to ISO 1520 "Paint and Varnish - Cupping Test" GB9753 standard. It mainly evaluates the properties of paints, varnishes, and related products that are resistant to cracking or separation from metal substrates after being gradually deformed under standard conditions. The test can be carried out according to the specified indentation depth, and the assessment is passed or not. The indentation depth may also be gradually increased to determine the minimum depth at which the coating is beginning to crack or begin to break away from the base material. Features: 1, in line with the ISO 1520 standard specification. 2. Evaluate the adhesion and elasticity of the metal surface treatment and paint surface. 3, digital display, resolution 0.01mm. 4. Rotate the handle to provide stable top pressure and high reproducibility. 5, magnifying glass with high-brightness lighting, a clear assessment of cracking situation. 6, ergonomic grip grip, replace the sample quickly and easily. Technical Parameters: 1, punch: Φ20mm 2, the maximum depth of depression: 10mm 3, measuring device: digital display, dividing value is 0.01mm 4, indentation accuracy: 0.05 5, test plate size: 70 × 70mm δ = 0.30 ~ 1.25mm flat deformation Polished steel plate, in line with GB9271 requirements
