Patent number: 5604024Abstract: Products of reaction of an aluminum compound (A), a boron-containing acid (B), a phosphorus-containing acid (P) and an amine (N) are characterized in that 1 mol of (A) has been reacted with from 0.3 to 1.19 mol of B, (from 1.8 to 2.19)+x mol of P and (from 0.3 to 3.69)+y mol of N, where x=from -1.5 to +1.5 and y=from 0 to 12. These reaction products may contain, if desired, up to 30 mol of water per mole of A employed and may be used in a very wide variety of ways, for example as binders, coating compositions or insulating material.Type: GrantFiled: November 14, 1994Date of Patent: February 18, 1997Assignee: Bayer AktiengesellschaftInventor: Wulf von Bonin
