Applications

Improved or equal performance is low-rolling resistance silica-reinforced tread compounds can be achieved at lower silane loading levels when AL180 silane is substituted for commonly used polysulfide-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 AL180 is substituted for slower cure-rate polysulfide-type silanes.
