PROBLEM STATEMENTPROBLEM STATEMENT

Customer had issue with the microfoams in the application of high built epoxyCustomer had issue with the microfoams in the application of high built epoxy floor coating and had used a lot of high end additives such as defoamers where increasing the dosage has afffected some properties of the paint film and it is not cost effectivenot cost effective.


• Customer sample without Defoamer was received.

TESTING PROCEDURESCustomer sample without Defoamer was received.

• Blank sample was applied prior to test our additive and analyze the

dry film appearancedry film appearance.

• The dry film without defoamer had lots of microfoams.

P t dditi P t dd AF 70 i d t diff t d d i d• Post addition Pat‐add AF 70 is done at different dosages and mixed

it well under stirrer.

• Samples were allowed to rest over night and the application was

done on cement panels using spike roller.

• Foaming observation was taken after curing of the film.
