Claim 1
Independent Claim
82 words
THE PROCESS OCC RENDERING A NON-WATERREPELLENT MATERIAL WATER-REPELLENT WHICH COMPRISES (1) TREATING SAID MATERIAL WITH A COMPOSITION COMPRISING AN AQUEOUS SOLUTION OF A WATERSOLUBLE METALLIC SALT OF A HYDROCARBON-SUBSTITUTED SILANETRIOL, THE METAL ION OF SAID SALT BEING A MEMBER SELECTED FROM THE CONSISTING OF ALKALI METALS AND ALKALINE EARTH METALS, AND (2) CAUSING THE FORMED HYDROCARBON-SUBSTITUTED POLYSILOXANE ON THE SURFACE OF THE TREATED MATERIAL TO BECOME WATER-INSOLUBLE BY DRYING THE TREATED MATERIAL UNDER MILDLY ACIDIC CCONDITIONS WHEREBY THE TREATED MATERIL BECOMES WATER-REPELLENT.

Claim 3
Dependent Claim
108 words
A COMPOSITION FOR RENDERING MATERIALS WATER-REPELLENT AND FOR IMPROVING THE FEEL OF SAID MATERIALS, SAID COMPOSITION COMPRISING AN AQUEOUS SOLUTION CONTAINING (1) FROM 10 TO 50 MOL PER CENT OF A WATER-SOLUBLE METALLIC SALT OF A HYDROCARBON-SUBSTITUTED SILANETRIOL, (2) FROM 50 TO 90 MOL PER CENT OF A WATER-SOLUBLE METALLIC SALT OF A DIHYDROCARBON-SUBSTITIUTED SILANEDIO!, EACH METAL ION OF THE METALLIC SALTS IN (1) AND (2) BEING A MEMBER SELECTED FROM THE CLASS CONSISTING OF ALKALI METALS AND ALKALINE EARTH METALS, AND (3), IN COMBINATION THEREWITH, A WATERSOLUBLE INORGANIC COPPOR SALT IN AN AMOUNT EQUAL TO 10 MOL PER CENT BASED ON THE METALLIC SALT OF THE SILANETRIOL.
