Cupping Tester

Accurately test coating resistance with minimal effort.

The CT15 Cupping Tester is a manual device designed to measure the deformation resistance of paints and coatings applied on aluminum or steel, in compliance with ISO 1520. This test is essential for quality control labs and helps assess both adhesion and flexibility when the coating is subjected to controlled cupping.

What is the CT15 Cupping Tester used for?

This tool simulates coating deformation using a 20 mm polished steel ball that presses against the test panel until visible cracks appear. During the process, the cupping depth is precisely measured.

Progressive, controlled deformation makes it easy to evaluate:

• The appearance of tensile cracks.
• The adhesion of the coating to the substrate.
• The mechanical behavior of the material under real-world flexing or stretching.

Key advantages of the CT15

• Smooth, consistent operation: Its mechanical design requires very little manual force.
• Precise speed control: 0.25 mm per turn, compliant with ISO standards (0.2–0.3 mm/sec).
• High-resolution digital readout: Displays cupping depth with 0.01 mm precision.
• Ergonomic and user-friendly: Designed for comfortable use, even during repetitive testing.
