The crystalline water-soluble constituents of an explosive mixture are waterproofed by applying to the surface of the crystalline constituents an hydrophilic component and then an ionogenic waterproofing component, thus producing a waterproofing substance in situ on the surface. The hydrophilic component ...
Process for waterproofing materials and the waterproofed materials so producedTextile material is made water-repellent by applying to the material or its fibres an organo-silicon compound in the liquid state or as a solution or emulsion, the compound being selected from substituted silanes of the ...
The composition may contain a carbonate or bicarbonate of an alkali metal or ammonium, or ammonium carbonate-carbamate or paraffin. The composition is prepared by adding an aqueous solution of a water soluble zirconyl or zirconium salt such as chloride, sulphate or nitrate to an alkaline solution ...
[Also in Divisions B2 and Di] A composition for imparting water-repellency to fibrous materials comprises (a) a thermosetting resin binder and (b) an oxazoline where R is C 1-3 alkyl, hydroxymethyl or -CH 2 -OOC-R2; R1 is C 12-22 alkyl; R2 is C 1-23 alkyl; and X is H 2 or...
