Claims47
Binder composition which comprises:
- (A) aluminum phosphate containing from 0 up to about 40 mole % of boron based upon the moles of aluminum and containing a mole ratio of phosphorus to total moles of aluminum and boron of about 2:1 to about 4:1;
- (B) nonpolymeric normally solid polyhydric alcohol soluble in aqueous solutions of the aluminum phosphate, and containing at least 2 adjacent carbon atoms each having directly attached thereto one alcoholic hydroxyl group;
- and keto tautomers thereof;
- (C) oxygen-containing alkaline earth metal compound containing alkaline earth metal and an oxide, and capable of reacting with the aluminum phosphate;
- wherein said alkaline earth metal compound includes a free alkaline earth metal oxide or a free alkaline earth metal hydroxide and wherein said oxide or hydroxide has a surface area no greater than about 8.5 m.sup.2 /gram (measured by the BET procedure);
- and
- (D) water;
- wherein the amount of aluminum phosphate is from about 50 to about 95% by weight based upon the total weight of aluminum phosphate and alkaline earth metal compound;
- the amount of alkaline earth metal compound is from about 50 to about 5% by weight based upon the total weight of aluminum phosphate and alkaline earth metal compound, the amount of water is from about 15 to about 50% by weight based upon the total weight of aluminum phosphate and water;
- and the amount of said alcohol is from about 0.5 to about 25% by weight based upon the total weight of aluminum phosphate and alcohol.

- and
- (C) water;
- wherein the amount of aluminum phosphate is from about 50 to about 85% by weight based upon the total weight of aluminum phosphate and water;
- the amount of water is from about 15 to about 50% by weight based upon the total weight of the aluminum phosphate and water;
- and the amount of the solid polyhydric alcohol is from about 0.5 to about 25% by weight based upon the total weight of aluminum phosphate and solid polyhydric alcohol;
- and
- containing in a second package a hardening agent for the curable composition in said first package being an oxygen-containing alkaline earth metal compound containing alkaline earth metal and an oxide wherein the amount of the alkaline earth metal compound is from about 50 to about 5% by weight based upon the total weight of the aluminum phosphate and alkaline earth metal compound.
