Silquest A-1589 Silane Bis-(triethoxysilylpropyl)disulfide Crompton-OSI Specialties Crosslinking / Coupling / Curing Agents >> Silane Rubber - Elastomer (Chloroprene, Butyl …) Silquest® A-1589 Silane bis-(Triethoxysilylpropyl)disulfide OSi Specialties Improved overall production costs and greater performance flexibility make Silquest® A-1589 disulfide silane a better choice. It is a silane that gives easier-to-process compounds in silica-filled tires and other filled rubber applications. When the sulfur is equalized in the curative step, Silquest A-1589 silane can provide performance equal to typical tetrasulfide products such as Silquest A-1289 silane at reduced use levels. Silquest A-1589 silane is designed for use in rubber applications where non-black, typically silica, fillers are used. Silquest A-1589 silane is intended to provide tire companies with options for enhanced tire performance and overall system cost-efficiencies. Additional improvements are anticipated as we continue to value customer needs as the nucleus of our new product design and development focus. Improved compounding rheology and reduced energy requirements More flexibility to tailor compound properties Optimization of cure rate, scorch time and crosslink density possible Ideal for sulfur-cure systems High flash point Bis-(triethoxysilylpropyl)disulfide. Used for sulfur-cured in rubber applications where non-black, typically silica, fillers are used. Exhibits good performance flexibility. Provides optimization of cure rate, scorch time and crosslink density. Possesses high flash point.
