Abstract
Abstract THIS INVENTION RELATES TO BONDING LIQUIDS HAVING A HOMOGENEOUS LIQUID PHASE WITH COLLODIAL SILICA DISPERSED THEREIN. THE BINDER LIQUIDS ARE ADMIXTURES OF AN ACIDIC AQUEOUS COLLODIAL SILICA SOL, A WATER MISCIBLE ORGANIC SOLVENT (SUCH AS ETHANOL) AND AN ALKYL SILICATE (SUCH AS ETHYL POLYSILICATE) OR AN ADMIXTURE OF AN ACIDIC ORGANOAQUEOUS COLLOIDAL SILICA SOL AND AN ALKYL SISLICATE. A PREFERRED BONDING LIQUID (STABLE FOR AT LEAST 60 DAYS AT 25* C.) CONTAINS ABOUT 15 WEIGHT PERCENT TO ABOUT 20 WEIGHT PERCENT OF SILICA, ACID IN AN AMOUNT TO PROVIDE A NORMALITY OF 0.005 TO ABOUT 0.02, ABOUT 80 WEIGHT PERCENT TO ABOUT 85 WEIGHT PERCENT OF ETHANOL, AND LESS THAN 1 WEIGHT PERCENT OF WATER.
