Abstract
Gel formers comprising acid aluminum phosphate and a reaction product of boric acid and an alkanolamine, and further comprising alkali metal compounds in the aluminum: alkali metal ratio of 1:1.3-2.5 require short gelling times, and form gels having improved melting resistance.
Claims10
A gel former containing a) an acid aluminum phosphate and b) a reaction product of boric acid with an alkanolamine, in which a) and b), calculated as solids, are present in a weight ratio of from 100:95 to 100:0.5 wherein the said gel former additionally contains one or more alkali metal compounds in an atomic ratio of aluminum to alkali metal of 1:1.3-2.5.
