Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a primer composition that shows improved hardness, adhesion, and mechanical properties.SOLUTION: Telechelic resins with reactive end groups (e.g., epoxy phosphate and epoxy ester) are synthesized using bisphenol-A (BPA) epoxide. The bisphenol-A based epoxide and the telechelic resins are all modified with tetraethylorthosilicate (TEOS) oligomers to produce epoxide/polysilicate (organic/inorganic) hybrid systems. The modified epoxides are thermally cured with a melamine-formaldehyde resin, cast on steel substrates. Salt spray analysis has revealed that the inorganically modified epoxides provide improvement over unmodified epoxide resins with respect to both corrosion resistance and adhesion to steel substrates.
