Crawling and cratering, 2 common paint defects, affect both the aesthetic & protective role of the coating film. Because they are often mixed up, formulators can spend hours focusing on the wrong solution.


Watch this tutorial and learn easy lab tests to identify with no doubt if you face cratering or crawling. You will then see the best approach to solve your coating defects, thus reducing your development time.


This video tutorial contains real lab experiences, courtesy of VLCI - Amsterdam, so that you know exactly how to solve crawling & cratering when you are back in your lab.
