EPOXY-BASED PRIMER COMPOSITIONS

摘要

The present application discloses a liquid epoxy-based primer composition comprising one or more free-radical scavengers in an amount of 0.5-20% by weight, said free-radical scavengers being selected from phenols and phenol multimers each substituted with electron-donating substituents, and application thereof by spraying. The application also discloses a coating system on a metal surface, comprising a coat of the epoxy-based primer composition (i.e. a primer coat) on at least a part of the metal surface, and a coat of a second coating composition (e.g. a top-coat) on at least a part of the primer coat; as well as an article coated with the primer composition.
