Polycarboxylate ether Rofluid H Rofluid H is a new generation admixture, which is a yellow to brown aqueous solution of polycarboxylate ether (PCE) with low viscosity. PCEs are compounds with a Latest generations, poly (carboxylate ether)-based superplasticizers, (PCEs), have acrylate groups in the backbone and also contain side chains (i.e., poly (ethylene oxide)) that protrude from the Polycarboxylate ether is a new generation plasticizer which is completely based tweak polycarboxylate and this application is very suitable and highly recommended for the construction process, civil engineering and for ready mix concrete. Polycarboxylate ethers (PCE) contain groups with polyoxyalkylene, especially polyethylene or polypropylene glycol groups as well as carboxylic acid and/or carboxylic acid anhydride monomers, e.g. acrylic acid, methacrylic acid, maleic acid and its anhydride, itonic acid and its anhydride.

The polycarboxylate ether comb-polymers consist of a polycarboxylate backbone and polyethylene oxide side chains bound to the backbone as esters. Polycarboxylate ether liquid is a high performance superplasticizer and water reducer for concrete. It can create a water reduction up to 40% with relatively low dosage (about 0.02-0.3% by cement weight) It is mainly used as a raw materials to produce different types of high performance concrete admixtures for targeted industries.
