Defoamers

Defoamers


The entrainment of uncontrolled air into cement based building materials leads inevitably to a loss of quality of high-performance concretes. Undesired air voids can weaken the system resulting in lower mechanical strength and abrasion resistance. A highly porous structure on the surface allows the penetration of harmful substances and can lead to surface defects.
