Flint Coat

ZEROCOR’s flint coat is a high temperature resin embedded with flint shards to create an extremely rough and hard surface for the OD of casing. Flint coat significantly enhances cement bond to casing as well as acting as a corrosion barrier.


  • Production casing through unconsolidated zones
  • Corrosive environments
  • Coated tubing between injection intervals
