Silquest RC-2 Silane sulfur-based silane Crompton-OSI Specialties Crosslinking / Coupling / Curing Agents >> Silane Rubber - Elastomer (Chloroprene, Butyl …) Silane useful for sulfur-cured, mineral-filled rubber applications, including silica-containing tires, belts, hoses and shoe soles. Easy compounding and scorch safety make this silane popular for coupling silica or other mineral reinforcements into rubber. Reduced heat-buildup, and improved modulus, tear strength, rolling resistance and abrasion resistance are achieved with this proprietary polysulfide silane. Dry silane forms can be produced by incorporating silane into carriers such as silica, silicates, waxes, absorptive thermoplastics, etc. More cost-effective performance may be achieved by adding liquid silane directly to the internal mixer during compounding, via injection or in premeasured volumes. Improved compounding and rheology Dynamic properties can be tailored Better scorch time than other polysulfide silanes Low odor Silquest RC-2 silane is distinguished from other sulfur-based silanes in that it produces low compound viscosity and improved scorch times. Sulfur-based silane. Used for sulfur-cured, mineral-filled rubber applications. Couples silica or other mineral reinforcements into rubber. Provides reduced heat-buildup, improved modulus, tear strength, rolling resistance and abrasion resistance. Produces low compound viscosity and improved scorch times.
