A preservative for wood and wooden materials contains more than 50 % by weight, relative to the total quantity, of at least one non-volatile, oil or oil-like, organic chemical solvent with an evaporation number above 35 and a flash point above 30 DEG C. In addition the agent contains 0.3 - 7 % by weight, relative to the total quantity, of at least one insecticide, soluble in the solvent described and/or in the binding agent, and/or 0.5 - 10 % by weight, relative to the total quantity, of at least one fungicide, soluble in the said solvent and/or in the binding agent used, as well as at least one binding agent, dispersable or soluble in the solvent described, as well as at least one further additive. Contained in the agent are 3 - 15 % by weight, relative to the total quantity, of the binding agent and, as additive, 3 - 10 % by weight, relative to the total quantity, of at least one finely divided, inorganic and/or organic swelling agent. The weight ratio of the binding agent to the swelling agent is 4:1 to 1:3.3 and the preservative has a viscosity of 300 - 4000 mPa.s, measured at 20 DEG C. |
