Polycarboxylate Ether PCE Powder (Water-Reducing Type)

Polycarboxylate Ether PCE Powder is a spray-dried form of liquid PCE superplasticizer, retaining the same comb-like molecular structure with polycarboxylate backbone and polyethylene oxide side chains. It is a free-flowing powder that dissolves rapidly in water, ideal for dry-mix mortar, grout, and applications where liquid admixtures are impractical.

Both are dry forms of PCE superplasticizer. PCE powder is produced by spray-drying and has finer particle size with faster dissolution, making it ideal for dry-mix formulations like self-leveling compounds and repair mortars. PCE flake has larger particle size and is typically preferred for on-site liquid admixture preparation at concrete plants. Both offer similar water reduction performance and slump retention.

PCE powder can be directly blended into dry-mix formulations at the factory, ensuring uniform distribution and eliminating the need for liquid admixture dosing at the job site. It provides consistent water reduction and workability when the dry mix is combined with water, improving adhesion, strength, and surface finish of self-leveling compounds, tile adhesives, and repair mortars.

PCE powder should be added slowly to water with gentle mechanical stirring at room temperature. Typical solution concentrations range from 10% to 40% active content depending on application requirements. The powder dissolves rapidly, usually within 15-30 minutes under proper agitation. Avoid high-shear mixing that could generate excessive foam or degrade polymer chains.

PCE powder should be stored in a cool, dry, well-ventilated area in tightly sealed containers away from moisture. The powder is hygroscopic and will absorb moisture if exposed to humid conditions. Under proper dry storage in original sealed packaging, shelf life is 12-24 months. Once opened, use promptly or reseal tightly to prevent moisture absorption and caking.
