High Quality Antifoam Defoamer Defoaming Agent for Concrete

Polyether defoamers are primarily synthesized from propylene glycol/glycerin, propylene oxide, ethylene oxide, etc., via potassium hydroxide-catalyzed reactions to form a highly effective defoaming solution. Characterized by environmental friendliness and high efficiency, this series is water-dilutable. Specifically developed for the cement concrete admixture industry—particularly for polycarboxylate superplasticizers—this defoamer is a novel high-carbon alcohol polyether ester formulation.

Defoaming  Agent Usage Instructions

◆ Pre-use Preparation: Stir well before use, as sedimentation or stratification 

      may occur after long-term storage.

◆ Dosage: Add directly to the polycarboxylate superplasticizer at a  

       recommended dosage of 1–3‰ (based on the weight of the

       superplasticizer). Mix thoroughly to form a homogeneous water-reducing 

       agent mixture.

◆ Application Tip: Stir the polycarboxylate superplasticizer for 20–50 seconds before use to ensure uniform dispersion.
