Abstract

Results of a physicochemical study of hydrolysis and gel formation in ethylsilicate binders without organic solvents are presented. The effects of the kind and amount of acid catalyst and the proportion of water to ethylsilicate on the thermal effect of the hydrolysis reaction, the sol-gel transformation, and the properties of the binder are investigated. IR spectra of gels of hydrolysates prepared by rapid and slow hydrolysis are presented. The technological aspects of production of binders are considered.
