Abstract The chromium complex is chemically bonded by ion exchange with alkali cations to strongly acidic sites in the glass surface. These sites are formed by the isomorphous replacement of silicon by boron and aluminum in the network structure. Polymerized complexes are better bonding agents than monomeric ones. Specific interactions between organic groups on the chrome complex and the bonding resins also determine laminate strength and water resistance.
