You are purchasing a downloadable pdf of this Standard.

This specification covers two types of highly pigmented zinc-rich coatings that are uniquely defined by their capabilities for protecting steel exposed at film discontinuities such as narrow scratches and holidays. 

The vehicle type may be inorganic (Type I) or organic (Type II). 

This specification does not cover weldable preconstruction primers such as SSPC-Paint 30. 

Zinc-rich coatings, both topcoated and untopcoated, have been used successfully in a wide variety of environmental zones. For a detailed breakdown of applicability of various types of zinc-rich coatings in different environmental zones, refer to SSPC-PS Guide 12.00. Consult the coating manufacturer for specific exposure recommendations. 

This coating is intended for application by spray for use by itself or as a primer in a multi-coat system.
