CAS No.: 40372-72-3
Corresponding other producer’s name：A-1289（OSi）、Z-6940（Dow Corning）、Si 69
（Degussa）
Product appearance：Yellowish clear liquid
Application:
1. It is a successful multi-purpose silane coupling agent which is used in rubber and
plastic industry. By its application, the rubber’s physical and mechanical properties can
be improved, tensile strength, anti- peel  strength, wear-resisting ,etc., can be
significantly improved, the permanent deformation can be reduced. Meanwhile it may
reduce the material viscosity and enhance workability.
2. It is specially suitable for the vulcanized rubber system which uses silica, silicate and
so on as reinforcing additive. Suitable fillers include silica, talc powder, clay, mica
powder, pottery clay and so on, and suitable polymers include NR, IR, SBR, BR, NBR,
EPDM etc..
Packing: Packed with 5L、20L、210L plastic/steel drum or 1000L IBC container, also can
be packed according to customer’s requirement.
Storage: Seal and store it in a cool, dry and ventilated place, keep moisture-proof and
waterproof, far away from kindling material and heat source.
