ABSTRACT:
Agent for impregnating materials that contain cellulose, mainly paper and wood. The active ingredient is a mixture of alkali aluminate and alkyl silanols that exhibits an intense hydrophobing effect at low concentrations. The agent can be employed in aqueous solution, e.g. in an enclosed space without the special exhaust devices required with volatile solvents. The solution is storage-stable. It contains preferably between 0.1 and 2.0% by weight of alkyl silanol and between 0.03 and 0.1% by weight of alkali aluminate.
