NapGard®

CORROSION-RESISTANT & ABRASION-RESISTANT COATING

Nap-Gard® NG65 Internal Pipe Coating is a thermosetting epoxy powder generally recommended for use in adverse temperature and pressure service applications that come in contact with corrosive oils, gases, and waters.  The abrasion-resistant coating exhibits high adhesion properties and due to its thick build provides excellent corrosion and wear protection.

This process of applying corrosion-resistant coatings ensures that the substrate (eg. Steel) is completely covered from the elements (Corrosive Oils, Gases, & or Waters) and extends the product life substantially through its superior corrosion resistance to the base material being coated.

NAP-GARD® NG65 comes in a multipurpose Red or Green
