Coolanol 25R

Silicate Ester Dielectric Heat Transfer Fluid Features and Benefits COOLANOL CHEMICAL STRUCTURE COOLANOL fluids are made up of silicate ester basestocks plus proprietary additives. Generically, silicate esters may be depicted as shown below. In this structure, a silicon atom is surrounded by four oxygen atoms. A hydrocarbon group, R, is attached to each oxygen atom. The R-O-Si combination is known as a silicate ester bond. It is the great flexibility of this bond that imparts superior low temperature viscosity characteristics to COOLANOL. Additionally, because the silicate ester molecule is relatively large and heavy, COOLANOL fluids have relatively low vapor pressures, which is another desirable characteristic of heat transfer liquids
