TEGO® Foamex 852
The Benefits
Defoamers for waterborne inks and varnishes work via a controlled incompatibility mechanism. An increase in defoaming strength typically correlates with a stronger tendency to create surface defects. With our new defoamer technology we break this rule. Compared to existing defoamers, TEGO® Foamex 852 can be: • more effective with similar compatibility • or more compatible with similar effectiveness
Breaking the rules
