Method of gelling water bearing compositions containing thickeners

Patent ·
OSTI ID:5306342

A method is provided for the very rapid gelling of cis-hydroxylated polymers, such as galactomannans, in an aqueous medium by adding thereto a selected crosslinking agent consisting of the product obtained by the admixture of a soluble trivalent antimony compound and a soluble hexavalent chromium compound in a polar liquid comprising at least 10% by wt of a glycolic substance having free cis-hydroxyl groups therein. The method is particularly useful in gelling a thickened aqueous explosive slurry, but is also useful in a wide range of coating or preservative applications. (7 claims)
