Defoamer For Concrete Admixture
Hangzhou Seraph Chem Corp. supplies a silicone based or organic based defoamer compound specifically formulated for concrete admixtures and water reducers. The liquid additive is engineered to suppress air entrainment during mixing and curing, which is critical for achieving a smooth surface finish and structural integrity in precast and ready mix concrete. It is supplied in bulk packaging to meet industrial demand.
The defoamer’s chemistry targets the foam generated by high shear mixing and chemical interactions in concrete formulations. Typical industry practice involves dosing at 0.05 to 0.2 % by weight of the admixture, depending on the water cement ratio and mixing energy. Standard tests for concrete defoamers include air content measurement via ASTM C231 and stability assessment under ASTM C618 for cementitious systems.
Construction chemical distributors and concrete producers source this additive to eliminate voids and pinholes in finished products. Buyers often confirm compatibility with superplasticizers, set retarders and other admixtures, as interactions can affect air content and workability. The product is available in 200 L drums or 1000 L IBCs, with lead times and Incoterms to be agreed during negotiation.

Request documentation such as ASTM C231 and ASTM C618 test results to ensure compliance with industry standards. Inspection of the first shipment for consistency in color, viscosity and activity is advised to confirm it meets your specifications.
