Crosile®69 reacts with silanol groups of white fillers during mixing and with the polymer during vulcanization under formation of covalent chemical bonds.
This imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties.
Crosile®69 is used in almost all fields of the rubber industry where silanol group containing white fillers are used and optimum properties are required.
Application fields are Low rolling resistance tires, mechanical rubber products, out shoe.
Crosile®69 is a kind of multifunctional silane coupling agent that has been used successfully in the rubber industry.
Crosile®69 is used to improve physical and mechanical properties of vulcanizates.
Crosile®69 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 rubber products.
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.
