Reactivity and Processability of the Hydrolyzing Silane Systems

Article Preview

Abstract:

Metal surface treatment by silane provides an alternative replacer to the existing toxic hexavalent chromium passivation technique. This article deals with the two fundamental aspects, viz reactivity and processability, of different hydrolyzing silane systems. By conductivity determination, the conversion of Si-OC2H5 into Si-OH and Si-OH condensation were studied for different hydrolyzing systems. The optimum hydrolyzed system was proposed based the desired balance of reactivity and processability.
