Structural steel primer.
For addressing corrosion on structural steel components, the Tnemec
Company, Inc. has introduced Series 394 PerimePrime, a one-component,
moisturecured, micaceous iron oxide, zinc-filled perimeter steel primer.
It offers triple corrosion protection--the first barrier is a
moisture-cured urethane film, the second layer uses MIO inside the
urethane to create a platelet barrier, with the final layer of
protection being an oxidation process that causes the zinc to fill any
voids the vapor used to infiltrate. It meets the American Institute of
Steel Construction requirements for class B certification over SSPC-SP3
prepared steel and is the first primer to receive UL Classification (UL
263/ASTM E 119) for use under select fireproofing materials. For more
