Equipment for Quality Control and R&D+i

Cupping Tester

Device to test the adhesion and extensibility qualities of paints, lacquers and other protective coatings applied to an aluminum substrate. Tests the extensibility and adhesive qualities of lacquers, paints and other protective coatings applied to a metal substrate. A 20mm diameter steel ball punch is applied under pressure to the uncoated side of the test panel. Concentric with the punch on the coated side of the panel is a corresponding die. As the test panel is deformed the coated surface is kept under observation and the point at which the coating cracks or becomes detached from the substrate is noted.

Elasticity & Resistance Deformation
Elasticity and resistance to deformation are part of the key physical properties required in the coatings industry today. Essentially there are three different test
methods which are used to determine a coating’s performance under different deformation conditions.

Cupping Test : A coated sheet metal is subjected to a gradual deformation by a polished die. This deformation is caused by the die being pushed from beneath the
coating – i.e. from the reverse side of the sheet metal. The end-point is when the coating begins to crack.
