Solubility
WD-80 silane is soluble in methanol, ethanol, isopropanol, mineral spirits, acetone, benzene, toluene, xylene, and in water when suitable hydrolysis procedures are followed.

Applications
Improved or equal performance is low-rolling resistance silica-reinforced tread compounds can be achieved at lower silane loading levels when WD-80 silane is substituted for commonly used polysulfied-type silanes. Mineral-reinforced articles such as shoe soles, rubber rollers and wheels, white sidewalls, and wire and cure accelerator systems and increased sulfur-donor concentrations may be necessary when WD-80 is substituted for slower cure-rate polysulfide-type silanes.
