Properties
OSi HIOSil 1298 is an oligomeric siloxane containing vinyl, propyl and ethoxy groups.
OSi HIOSil 1298 is a further development of OSi HIOSil 172, vinyl-tris(2-methoxy-ethoxy) silane.
OSi HIOSil 1298 is a colorless, nearly odorless low-viscosity liquid. OSi HIOSil 1298 is an excellent silane compatibilizer between inorganic fillers (e.g., kaolin, MDH, ATH) and organic polymers (EPDM, EVA, PE).
Vinyl Silane Polymer OSi HIOSil 1298 vinyl oligomeric siloxane is excellent as an adhesion promoter in mineral-filled, peroxide-crosslinked compounds. The silicon-functional ethoxy groups of OSi HIOSil 1298 hydrolyze in the presence of moisture, which is usually present on the filler surface, forming active silanol groups. The condensation of these silanol groups with hydroxyl groups on the filler surface leads to a tight chemical bond between OSi HIOSil 1298 and the filler. The vinyl functional end of OSi HIOSil 1298 can be coupled to the polymer in a further reaction that runs parallel to peroxide crosslinking.
A major field of application for mineral-filled compounds is the cable industry. EPDM and kaolin can be processed into cable compounds through the adhesion-promoting and hydrophobic effects of OSi HIOSil 1298. It can also be used in the manufacture of halogen-free, non-toxic, environmental flame-retardant compounds (HFFR) based on EVA or PE and ATH or MDH. In addition, OSi HIOSil 1298 can be used in many other applications such as filler and pigment treatment, use in dispersions, etc.
