To make its non-porous and seamless claims, there needs to be a top-coat on it. But because cementitious urethane flooring is concrete, this topcoat is really the only floor. Some installers put the top-coat straight on the concrete but, at the end of the day, cementitious urethane is more or less equal to applying a coat of paint.
When you look at the composition, as both contain Phosphoric acid you might think it can be used but it cannot be. There is a slight difference in the percentage of Phosphoric Acid concentration and also in Zinc Phosphate cement the liquid contains Water and Aluminum phosphate which act as dilutants along wit Zinc and Aluminum which make it not usable as an etchant.
Polyvinyl acetate is also the raw material to make other polymers like: Polyvinyl alcohol-[HOCHCH 2]-: Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macromolecules.

This compound is added to slip, which is a thin liquid clay used to attach pieces of unfired ceramics, or greenware. For example, a potter would coat the edges of a cup handle before attaching it to the cup. The addition of sodium silicate reduces the amount of water needed to make the slip, so there is less shrinkage during the firing process.
