MODERNER TCB Cupping Tester coating Cupping Tester φ 20mm punch

Introduction

Cupping Tester, also known as coating cupping Tester, can be used to determine the stretchability or adhesion of paint films. It is designed and manufactured in strict accordance with the ISO 1520 "Paints and Varnishes - Cupping Test" GB9753 standard for MODERNERs. The cupping Tester mainly evaluates the resistance to cracking or separation from the metal substrate of coatings of paints, varnishes and related products after they are gradually deformed under standard conditions. Conduct the test according to the specified indentation depth and evaluate whether it passes or fails. The depth of indentation can be gradually increased to determine the minimum depth at which the coating first appears to crack or begins to separate from the base material. The measured data will be displayed on the LCD of the cupping instrument, and the indentation accuracy reaches 0.05.

Instructions

(1) Turn the handwheel of the cupping instrument in the "down" direction (clockwise) to the end, loosen the upper test plate pressing head of the testing machine, insert the test plate with the coated side up into the gap, and connect the punching head and Align the center of the test plate, tighten the test plate clamping head, and firmly fix the test plate on the stamping die.

(2) Turn on the power switch on the rear panel of the device, and 00.00 should be displayed on the display.

(3) Rotate the handwheel in the "up" direction (counterclockwise) to raise the punch head. When the rotation is close to 3 turns, you should slow down and rotate at a speed of about 3 seconds. When the stamping head first contacts the sample, the counter conducts electricity and starts counting, and the counter reading machine is the indentation depth.

(4) Continue to rotate the handwheel until the specified depth is reached, and observe the test plate to determine whether the sample is qualified; you can also gradually increase the indentation depth to determine the minimum depth when the coating first cracks or begins to separate from the base material.
