SiSiB® WR5132 is a clear, colorless liquid of poly(methylethoxy)siloxane, ethoxy-terminated. It is highly miscible with organic solvents and insoluble in neutral water. It accelerates hydrolysis with catalysts and is used as a water repellent to improve filler dispersibility.
SiSiB® WR5132 is poly(methylethoxy)siloxanes, ethoxy terminated. It is a clear colorless liquid.
Color and Appearance | Colorless clear liquid |
Active Component | Min.98.0% |
Density 25°C | 0.92~1.02 |
Viscosity (25°C, cSt) | 1.0-5.0 |

SiSiB® WR5132 is highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone.
SiSiB® WR5132 is practically insoluble in neutral water and reacts only slowly to form silanols and higher condensation products. Addition of a hydrolytic catalyst (inorganic/organic acids, ammonia or amines) accelerates the hydrolysis of SiSiB® WR5132 substantially.
SiSiB® WR5132 may be used as water repellent to improve fillers dispersibility and reduces their sedimentation tendency.
SiSiB® WR5132 is supplied in 190Kg steel drum.
In the unopened original container SiSiB® WR5132 has a shelf life of one year in a dry and cool place.
