Bis Triethoxysilylpropyl Disulfide Silane Coupling agent Si 75
Crosile@75 (Bis(3-triethoxysilylpropyl)disulfide) TESPD is a bifunction polysulfidic organosilane and has been widely in the rubber industry.
TESPD is used to improve the reinforcing capability of fillers with silanol group on the their surface,and also as an integral part of curing systems to improve cross-linking network properties.
Crosile 75 has a higher temperature stability and therefore allows higher mixing temperatures.
Crosile@75 imparts greater tensile strength, higher module, reduced compression set, increased abrasion resistance and optimized dynamic properties.
Application fields are: Low rolling resistance tires

Application Range
- An oustanding characters is the low-active disulfide group of Si 75 ,so it is more reliable and provides more scorch safety..
- It is able to markedly improve tensile strength, tearing strength and abrasive resistance ,another it also can reduce compression set of vulcanizates.
- In addition, it can reduce the viscosity and improve the process ability of rubber products.
- SI 75 is especially suitable to improve the reinforcing properties of fillers that contain hydroxyl groups in all unsaturated polymers having double bonds or their blends.
- Silica, talc powder, mica powder and clay can be applied in combination with silane coupling agent
- In addition silane can applied with polymers such as NR, IR, SBR, BR, NBR and EPDM.
