Series 90-97


Generic Type

Aromatic Urethane, Zinc-Rich

Common Usage

An advanced technology, two-component, moisture-cured, zinc-rich primer providing extraordinary performance. It’s user friendly and rapid curing so chemical- and corrosion-resistant topcoats can be applied the “same-day.” Also used for field touch-up of inorganic zinc coating. Application methods include “dry-fall” under certain conditions (see Application).

Special Qualifications

Series 90-97 meets AISC requirements of Class B surface with a mean slip coefficient no less than 0.50 and a tension creep not in excess of .005 inches (.13mm).

Tneme-Zinc uses a zinc pigment 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 0.009% lead by weight) as defined in 16 CFR Part 1303 of the Consumer Product Safety Commission regulations. Conforms to SSPC Paint 20, Type II.

This product is part of a coating system tested in accordance with ISO 12944-6 (2018). Contact your Tnemec representative for coating system test results.
