| Description |
Epoxy-polyamide coatings are used to protect metallic substrates in corrosive atmosphere. Thermal stability
of the coating can be improved by the addition of inorganic cross-linking agent. Epoxy resin is
incorporated with small percentage of silicone resin and cured with two types of hardeners such as
polyamide and butyl titanate. The physical properties, heat resistance properties and electrochemical
impedance behaviour of these coatings on steel in 0.5M NaCl solution have been studied. The result
implies that the heat resistant character of the titanate-cured coating is increased from 260 to 370 ◦C.
The impedance study has shown that the coating resistance exerted by both the systems is in the range
of 105 �cm2 after 6 days of immersion in 0.5M NaCl. FTIR and Raman spectroscopy analysis confirm
the presence of titanate linkage in the cured polymer coating. Thermal stability data indicate that the
epoxy silicone resin cured with titanate hardener possesses higher thermal stability than that cured by
polyamide hardener.
