Poly ethoxysilane

Angular silicas such as Partisil and Lichrosorb are prepared by the reaction of sodium silicate with hydrochloric acid. Spherical particles, e.g. Spherisorb are synthesised by the hydrolytic polycondensation of poly-ethoxysilane followed by emulsion precipitation or spray-drying. 

Several adhesives are available, including poly-L-lysine, 3-aminopropyltri-ethoxysilane (APES), Vectabond (Vector Laboratories Ltd.). Treated slides are also available commercially, as are electrostatically charged slides that are especially effective with fresh cell preparations. The most cost-effective method is to prepare adhesive coated slides in-house . APES (5) is the section adhesive of choice large numbers of slides can be prepared in batches, dried, and stored indefinitely without deterioration. The adhesive qualities are excellent and are vastly superior to those of poly-L-lysine, for example. 

A poly(VDF-co-HFP) copolymer is appHed to a metalhc substrate, as coating composition and crosslinked with amine, diamine, or ethoxysilane [192]. This cured polymer is used as thick or thin free standing films, or thick or thin films with good adhesion to metallic or other rigid surfaces [192]. Moreover, diamine-cured PVDF can be used as strong adhesive joints without prior surface modification [31].
