Summary: | According to the invention a hydrophobing agent is composed of a resinic acid and/or a fatty acid, which are emulsified/dispersed in an aqueous phase of water, a polyaluminium salt dissolved in the water and preferably also a cationic organic compound. According to the invention the hydrophobing agent is manufactured in that the resinic acid and/or the fatty acid, possibly mixed with another hydrophobic agent that reduces the melting point, are finely dispersed in the aqueous phase in the presence of the polyaluminium salt and preferably also the cationic organic compound. The invention also relates to the use of the hydrophobing agent for stock hydrophobing of cellulose fibres in paper manufacture. |
