Product Details
TQC Sheen Automatic cupping tester to perform a cupping (Erichsen / Dent) test on coated steel panels to define the resistance of paint, varnish or related products to cracking and/or detachment from a metal substrate when subjected to gradual deformation by indentation under standard conditions.
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.
Features
Constant deformation
The ISO1520 standard requires panels to be slowly deformed at a steady rate between 0,1 mm/s and 0,3 mm/s without interruption. Especially with thicker steel panels hand-operated testers not always allow an uninterrupted deformation. The Automatic cupping tester is driven by a micro-step controlled electro motor which allows precise and steady deformation with 0,01 mm steps. Uniquely this deformation can be paused / resumed.
Unique Interface
Each Automatic cupping tester is equipped with the Triple I ® Navigation Tool. This Intelligent Illumination Interface guides the operator through the TQC Sheen lab-machines. At each step of the operating menu the interface detects which buttons are active and indicates these by means of an illuminated red center This results in a very intuitive operating system which is enhanced with information on the machine’s full colour display.
Numerous set-ups
The Automatic cupping tester has numerous set-ups. The custom set-up optionally is password-protected, and after each set number of test runs statistics are shown. Also the illumination of the test specimen can be set-up. To guarantee maximum visibility of all possible types of surface including high gloss, matte or colored samples the TQC Sheen Automatic cupping tester is equipped with a complementary light system of which the colors can be changed to achieve maximum contrast. The strength of the LED’s is adjustable as is the direction of the light source.
