A corrosion resistant, alkali resistant coating composition is disclosed. The composition comprises a binder comprising a reaction product of an epoxy-containing material and a phosphorus-containing material together with a curing agent. Aminoplasts, especially melamine-based aminoplasts, are particularly suitable curing agents. A source of silicon can optionally be included. The compositions also provide excellent adhesion and can be used with or without a weldable primer. The compositions are applied to and cured on a metal substrate. L'invention concerne une composition de revêtement résistant à la corrosion et aux substances alcalines. Cette composition contient un liant comprenant un produit de réaction d'un matériau contenant de l'époxy et un matériau contenant du phosphore ainsi qu'un durcisseur. Des aminoplastes, notamment des aminoplastes à base de mélanine, sont particulièrement utiles en tant que durcisseurs. Une source de silicone peut être facultativement utilisée. Ces compositions présentent aussi une excellente adhésion et peuvent être utilisées avec ou sans amorce soudable. Ces compositions sont appliquées et durcies sur un substrat métallique.
