Silane coupling agent Crosile 69 is a kind of multifunctional silane coupling agent that has been
used successfully in the rubber industry. It is used to improve
physical and mechanical properties of vulcanizates. It is able to
markedly improve tensile strength, tearing strength and abrasive
resistance and reduce compression set of vulcanizates. In addition,
it can reduce the viscosity and improve the processability of
Silane coupling agent Crosile - 69 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 used in combination with Crosile - 69 in polymers such as NR, IR, SBR, BR, NBR and EPDM.
