Biotin R is a concentrated liquid preparation of active substances to be used, subject to dilution, for the preservation of surfaces like stone materials, mortars, plasters, frescoes, bricks, etc., from microbiological attack and then .
Biotin R is used in solutions in organic solvents - concentrations ranging from 3 to 5%.
Biotin R provides an enduring protection, thanks to its very low solubility in water which allows long-lasting activity also following repeated washouts. Owing to its characteristic of being soluble in organic solvents (both polar such as acetates and apolar such as White Spirit D40), Biotin R proves to be useful not only for the protection of outdoor artifacts but even of supports sensitive to water, e.g. wooden materials, backs of canvas paintings, frescoes containing soluble salts.
