Fillers organosilane treated

Further examples of application of DRIFTS, and other surface analytical techniques, to organosilane treated fillers and interphase characterisation in organosilane modified composite, have been reviewed by Suzuki and Ishida [51]. 

Wollastonite is very amenable to organosilane treatments, and is often treated with reactive groups such as amino, epoxy, vinyl and methacrylate. Amino- and mercapto-silanes will bond the filler to PVC the others can assist in various crosshnking mechanisms. In recent years, silanes with nomeactive groups, such as dialkyl ligands, have also been utilized. Although not producing resm-fiUer bonds, these silanes improve ease of dispersion and reduce abrasivity. It is likely that titanate or zirconate treatment will provide similar results.
