VERA-BARRIOS, Bertha S.  and  LAZO-ALARCON, Luis A.. Borosilicate clay as waterproof coating on sanitary furniture obtained from high concentrations of residual boric acid. Inf. tecnol. [online]. 2020, vol.31, n.4, pp.125-138. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642020000400125.

The objective of this research study is to use residual boric acid as an input to make a highly polished and waterproof vitreous enamel that is "low absorption" and that is used to cover sanitary furniture for rapid waste runoff. Four sub-types of mixture were prepared: three with different concentrations (10, 20, and 30% by weight) of boric acid with respect to the total weight of the rest of the inputs and one mixture for one control sample not including boric acid. Considering “boric acid” and “impermeability” as study variables, the results were validated by first applying the statistical model of a single-factor random block Anova followed by the statistical T-Student test. The specimens coated with 20% (by weight) borosilicate absorbed less water than the other reference specimens. This study demonstrates an environmentally friendly alternative for waterproof coating that can be used in the future.

Keywords : clay; waterproof; enamel; sanitary; boric acid.
