Description

Chemical name: Vinyltri(2-methoxyethoxy)silane oligomer

RJ-172SO is a vinyl functional silane oligomer, based on RJ-172, vinyl-tris (2-methoxyethoxy)silane. RJ-172SO is a colorless, low-viscosity liquid. RJ-172SO can improve the dispersibility of inorganic fillers with organic polymers. RJ-172SO has higher boiling start and higher flash point compared to monomeric silanes, which leads to several advantages on safety, handling and processing.

Application

Silane RJ-172SO is an excellent adhesion promoter in mineral-filled, peroxide-crosslinked compounds. A major field of application for mineral-filled compounds is the cable industry. EPDM filled with kaolin can be processed into cable compounds through the adhesion promoting and hydrophobic effects of RJ-172SO. It also can be used in the manufacture of flame retardant compounds(HFFR) based on EVA and ATH or MDH. In addition, RJ-172SO can be used in many other applications such as filler and pigment treatment, etc.
