| abstract |
The present invention concerns combinations of a water repellent alkyl ketene dimer as a component (I) and a water repellent metal alcoholate as a component (II) that are strongly synergistic in repelling water from water absorbing surfaces, resulting in a surprisingly long water droplet absorption time. The combinations of the invention can be applied to the surface of any material that has water absorbing properties such as, but not limited to, wood, woven and non-woven sheeting materials, paper, building materials, gypsum board, and leather. |
