BIOCIDAL PRODUCT WITH LUMINESCENT MARKER ADDITIVE FOR TEXTILE SURFACES OR THE LIKE
A biocidal product for application to surfaces, particularly porous surfaces such as fabrics, textiles and the like, incorporating an identification marker which makes it possible to certify the presence of the product and therefore that protection is kept. This biocidal composition includes an ester vinyl resin between 0.01 and 0.05% with respect to the total weight of the product, which acts as a carrier for the biocidal agents, a mixture formed by the combination of between 0.1 and 2.0% dimethyl didecyl ammonium chloride and between 2.0 and 10.0% dimethyloctadecyl [3-(trimethoxysilyl)propyl] ammonium chloride in a medium formed by the mixture of 0.2 to 1.0 methanol and 0.02 and 1.50 ethanol, urea in a proportion between 0.2 and 1.0% and acetic acid between 0.001 and 0.010; and the luminescent additive incorporates aluminosilicate metallic oxides containing rare earth ions by way of doping agents.
