Description
The TQC Sheen Automatic Cupping Tester is a precision instrument designed to assess the flexibility and adhesion performance of coatings by measuring their resistance to deformation using a controlled mechanical cupping action. This test is essential for evaluating how well a coating can withstand bending and elongation without cracking, which is critical for protective coatings, industrial finishes and flexible substrates. By automating the cupping process, the system delivers consistent, repeatable results with minimal operator influence, making it ideal for laboratory, quality control and production environments. The test is either used as a “pass / fail” test by testing to a specified
depth or defining the minimum depth at which a coating fails by
gradually increasing the indentation.

How It Works
- Mount the coated test panel securely in the cupping tester frame.
- Select the appropriate punch diameter and speed for the test specification.
- The automated mechanism drives the punch against the coated surface, forming a dome shape.
- Observe and measure the deformation until the coating shows signs of cracking or failure.
- Record the cupping depth at which the coating first fails or shows defects.
- Compare results against internal criteria or standards to evaluate coating flexibility and performance.
