Sourcing Polycarboxylate Ether (PCE)? ChemicalDekho connects you with leading construction chemical manufacturers like BASF (MasterGlenium) and Sika (ViscoCrete), along with specialized domestic producers. Access the most advanced admixture technology for modern concrete.
PCE (CAS 62601-60-9) is a comb-polymer that disperses cement particles via steric hindrance. This mechanism allows for massive water reduction (up to 40%) while maintaining high workability (slump) for hours. It is the critical ingredient for High Performance Concrete (HPC), Self-Compacting Concrete (SCC), and precast elements.
Listings cover standard 50% solid content liquids for ready-mix plants and spray-dried powders for dry mortar blends.

Generally non-toxic and non-flammable. May cause mild skin or eye irritation upon prolonged contact. Slippery when spilled.
PCE is a 3rd generation superplasticizer. It offers higher water reduction (40% vs 20%) and better slump retention than SNF (2nd gen), but is more sensitive to clay in aggregates.
Yes, but it is very potent. Typical dosage is only 0.2% to 1.0% by weight of cement. Overdosing can cause segregation (bleeding).
Liquid (50%) is standard for concrete batching plants. Powder is used for dry-mix mortars (like tile adhesive) where water is added later at the site.
Standard PCE does not significantly retard setting, but specific 'Retarding' grades are available for hot weather concreting.
