Synthesis and research of polyfunctional silylureas used in electric deposition of tin-indium alloy

Polyfunctional silylureas were synthesized by the interaction of 3-aminopropyltriethoxysilane with isocyanates various structures in an inert aromatic solvent. Commercially available diisocyanates such as isophorone diisocyanate, hexamethylene 2,4-toluene diisocyanate used isocyanates. In this case, freshly distilled toluene was a The obtained compounds confirmed data IR and NMR1H spectroscopy. Using compounds, formulations compositions for electrodeposition tin-indium alloy on copper wire developed. possibility using effective surfactants is shown. operational characteristics investigated, including diameter, coating thickness, tensile strength, electrical resistance, direct current resistivity.
