High-Efficiency Defoaming for Cement Mortar

Foam in cement mortar and concrete production causes internal voids, reducing compressive strength and surface finish. Chemi Tech's defoamer powder uses polysiloxane as the base material, compounded with white carbon black and hydroxyl silicone oil. It rapidly collapses bubbles by breaking surface tension and suppresses foam regeneration. The powder form ensures easy dispersion in dry-mix systems, maintaining stability across pH 1-14 and temperature fluctuations, even in highly alkaline cement environments.

Case Study: Precast Plant Solves Strength Inconsistency

A precast slab manufacturer faced 15% compressive strength variation and 8% surface porosity due to high air content (12%) in mortar. After adding 0.3% Chemi Tech KM-268 defoamer powder:

Density Improvement: Bubble residue dropped to 3%, increasing 28-day compressive strength by 18%;

Surface Optimization: Slab smoothness improved, reducing repair rate by 70%;

Cost Control: Raw material waste decreased by 5% per ton without adjusting mix design.

Suitable for masonry mortar, waterproofing mortar, and self-leveling compounds, this defoamer integrates with automated batching systems to shorten curing cycles.
