Pat Add AF 70 in Epoxy High Built Floor Coating PROBLEM STATEMENT Customer 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 notcost effective.

Pat Add AF 70 in Epoxy High Built Floor Coating TESTING PROCEDURES Customer sample without Defoamerwas received. Blank sample was applied prior to test our additive and analyze the dry film appearance. The dry film without defoamer had lots of microfoams. Post addition Pat add Pt 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.
