Weld-Through Inorganic Zinc Primer
This specification covers a group of inorganic zinc primers that can protect carbon steel during the fabrication process, permit welding to specification requirements, and be overcoated. The major pigment component in this coating is zinc dust and the binder is inorganic. This specification defines the minimum compositional and laboratory performance requirements for characterizing a group of zinc primers. It is to be used in conjunction with SSPC-PS Guide 22.00, SSPC-PS Guide 12.00, and other SSPC specifications covering surface preparation, application, thickness, inspection, and safety.
