Technical service engineers measure the coating’s release force electronically with the aid of a peel-force measuring device. Different tests show how the coating behaves at a peel angle of 90 degrees or 180 degrees, for example.
The test results are illustrated graphically. The DEHESIVE® Coating Center’s database already contains 50,000 test results. However, if you think that this means that the Care & Coatings business team will soon have covered all conceivable material constellations, you are mistaken. “The paper quality available on the market is constantly changing. And new adhesives are continuously posing challenges, too,” explains Lautenschlager. He believes that, while the test results to date point the way ahead, they are by no means definitive.
Release coatings thus require further research, so that shampoo, melons, etc. will be optimally labeled in the future, too.
