Abstract:
A coating material or treatment composition for protecting wood and/or cellulosic substrates against biological material destruction, consisting of:(i) from 2 to 50 percent of a water-emulsifiable binder selected from the group consisting of (a) water-emulsifiable natural oils, (b) water-emulsifiable synthetic oils, (c) water-emulsifiable alkyd resins based on natural oils, (d) water-emulsifiable alkyl resins based on synthetic oils, and (e) mixtures of at least two of binders (a), (b), (c) and (d); (ii) from 0.5 to 40 percent of a biocidal component that is at least one quatemary ammonium salt, the quaternary ammonium salt having at least one alkyl group having 6 to 24 carbon atoms; (iii) optionally, from 0.01 to 10 percent of at least one biocidal agent other than biocidal component (ii) and other than a primary, secondary or tertiary amine or salts thereof; (iv) optionally, at least one auxiliary or additive member selected from the group consisting of (a) agents that protect the coating material or treatment composition against UV light, (b) agents that protect the coating material or treatment composition against aging, (c) colorants, (d) decorative agents, (e) agents that promote adhesion for the rest of the coating material or treatment composition, and (f) hydrophobicization agents; and (v) a sufficient amount of water for the coating material or treatment composition to be in liquid form, said coating material or treatment composition being storage-stable, being transparent unless made non-transparent by said optional colorant or decorative agent, and having an absence of any organic solvent.
