PCE Liquid (Polycarboxylate Ether Superplasticizer)

Anionic polyacrylamide is a high molecular polymer formed by the free-radical polymerization of acrylamide monomers. Its molecular chains contain a large number of negatively charged groups, which can bind with positively charged particles. It exhibits excellent flocculation performance and shear resistance, making it an indispensable chemical additive in industrial water treatment, mineral processing, and oil and gas extraction.

Notes

Recommended Dosage
The recommended dosage is 0.2% -0.8% of the total amount of concrete cementitious material, and the specific dosage needs to be determined through experiments.
Dissolve and Mix
PCE liquid can be directly added to concrete mixing water to ensure thorough mixing. It is not recommended to mix directly with other undissolved additives to avoid affecting performance.
Medical Industdies
Before use, it is recommended to conduct an adaptability test to ensure good compatibility with the cement and admixture used.
Temperature Control
This product is suitable for ambient temperature range of 5 ° C to 40 ° C , low temperature may affect solubility and dispersibility.
Storage and Valid Period
Store in a cool, dry, and ventilated environment, avoid direct sunlight and frost.• The shelf life of the product is 12 months in the unopened state , and it should be used as soon as possible after opening.
Environmental Safety
