NOVEL FAST CURING ULTRA HIGH SOLIDS LOW VOC COATING SYSTEM FOR AGGRESSIVE CORROSIVE ENVIRONMENTS

摘要

The present application discloses a non-thermosetting coating system consisting of : a first layer of a primer composition comprising an epoxy-based binder system having a volume solids % (VS%) of at least 82%; and a second layer of top-coat composition comprising a polyurea-based binder system having a VS% of at least 82%; wherein the weighted average VS% of the coating system is at least 84%. The application further discloses a coated structure carrying the coating system; a method for the establishment of a coated structure using the coating system; a zinc epoxy primer composition comprising an epoxy-based binder system and 20-40% by solids volume of the primer composition of zinc and having a VS% of at least 82%; and an epoxy primer composition comprising an epoxy-based binder system having a VS% of at least 82% and a "dry-to-handle" time which is less than 5 h at 20 °C.
