Application

1. Crosile® 69 is a kind of multifunctional silane coupling agent that has been used successfully in the rubber ,tyre industry. It is used to improve physical and mechanical properties of vulcanizates.

2. 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.

3. 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 Si 69 in olymers such as NR, IR, SBR, BR, NBR and EPDM.
