RIsol FL480S is a fully synthetic viscosifying and non-retarding fluid loss additive. It offers a delayed gel strength development to provide right angle set characteristics to the slurry. The non-retarding properties are ideal for light cement compositions which in many cases exhibit extended thickening times. This product shows excellent performance in sea water and salt concentrations up to 18%. Risol FL480S keep similar rheological data with original Halad 344 and Polytrol FL34, meanwhile it keeps good fluid loss in different cement slurries.Risol FL480S is a mid to high temperature fluid loss additive. The typical dose is 0.4-1.2% BWOC.
