Silane Coupling Agent HP 669

CAS: 40372-72-3 Equivalent to : SI-69 (Degussa)，Z-6940 (Dowcorning)，A-1289 (Crompton)，KBE-846 (Shin-Etsu)，KH-845-4 (China) HP-669 is used successfully in the rubber industry as a dual functional organic poly sulfur silane coupling agent. 1. HP-669 can be used in the vulcanized rubber system with fillers such as silica, fiberglass, talc powder, mica powder and clay as reinforcing agent. It can improve the reinforcing properties of fillers and rubber abrasive resistance properties. 2. In dynamic and static conditions, It is used for producing these rubber products: tire, hose, rubber roll, belting, cable, footwear and mechanical founding products. It can improve abrasive resistance, cutting resistance and pressure resistance, reduce hysteresis loss and hygroscopicity, improve mechanical and adhesive properties, and increase thermal ageing performance.
