Defoamers for Polycarboxylate Superplasticizer (PCE) Water Reducing Agents
Entrained air during the high-shear mechanical blending of polycarboxylic acid (PCE) based water reducers and concrete admixtures significantly compromises finished concrete compressive strength parameters and structural durability metrics. Severe air pocket expansion within the cement matrix decreases concrete density limits and accelerates dynamic degradation tracking under harsh environmental stresses.
INVINO® formulates phosphorus-free polyether ester fluids and advanced alkylene oxide block copolymers engineered for absolute chemical compatibility with complex PCE monomer backbones. These active agents prevent surfactant layer separation and macro-froth expansion inside concentrated admixture matrices, ensuring reliable air content control without disrupting the baseline stability parameters of the core formulation.

Technical Benefits for Admixture Formulators
Formulated using specialized non-ionic surfactant barriers that guarantee uniform solubilization inside high-salt polycarboxylate and lignosulfonate matrices, avoiding phase separation boundaries or droplet precipitation over 12-month shelf life windows.
Delivers continuous bubble rupture boundaries throughout concrete agitation transport trucks, commercial transit loops, and heavy pumping operations, maintaining consistent entrained air volume metrics until hydration curing.
Remains completely chemically inert to tricalcium silicate mineral phases and free radical catalyst residues, ensuring zero retardant or acceleration interference on concrete cement stone hydration kinetics.
