How to evaluate defoamer? click here-one of our customer test result about our sample and bulk sample in their lab.

We delivered one FCL defoamer to our customer, but when they received goods, they told that they need to evaluate bulk sample to confirm the defoamer stable ability with previous sample that we sent them.

The result is no problem, and customer satisfied with our defoamer, and further order another FCL after one month.Below pictures are my customer test result and test method.
