Aromatic Polyurethane, Zinc-Rich
An advanced technology, single-component, moisture-cured, zinc-rich primer providing extraordinary performance, user-friendly and easy application. Also used for field touch-up of inorganic zinc coating.
90-1K97 Tneme-Zinc uses a dust which meets the requirements of ASTM D 520 Type III and contains less than .002% lead. This level qualifies it to be classed as "non-lead" (less than 0.06% lead by weight) as defined in Part 1303 of the Consumer Product Safety Act Regulations. Conforms to SSPC Paint 20, Type II.
2.5 to 3.5 mils (65 to 90 microns) per coat.

Series 115. Intermediate coat color should be noticeably different but in the same family as the topcoat color. Certain intermediate/topcaot systems may require multiple coats to achieve acceptable hiding, depending on color, specified thickness per coat and method of application.
