KNOCKDOWN 155 is a non-silicone defoamer created specifically for the graphic arts industry. The wide variety of ink formulations requires a broad selection of defoamers. KNOCKDOWN 155 defoamer has proven to be most effective and economical in resolving the most difficult problems of excess foam.
KNOCKDOWN 155 defoamer is best suited for styrene-acrylic systems with moderate to high acid number polymers.
Ideal use levels may vary from system to system. If used as received, we suggest 0.25-0.75% of KNOCKDOWN 155 defoamer based upon the total weight of the ink or coating.
Stock solutions may be prepared by adding one part of KNOCKDOWN 155 defoamer to two or three parts of warm water (120°F) with agitation. If allowed to stand for extended periods, such stock solutions may require mild agitation before use.
