Series 90-75


Generic Type

Open Matrix, Zinc Rich Epoxy

Common Usage

Series 90-75 is a waterborne, zinc-rich epoxy that offers extended protection to steel surfaces in industrial and marine environments. This innovative coating forms a micro-porous polymer structure in the dry film improving the conductivity between the zinc particles which provides superior galvanic corrosion protection. Its ultra-low VOC formulation cures quickly and provides outstanding long-term corrosion resistance when used with other Tnemec high-performance coatings. U.S. patent pending.

Special Qualifications

Tneme-Zinc uses a zinc pigment that 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.

Series 90-75 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).

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.

Series 90-75 meets the requirements of LEED-Low-Emitting Materials, Collaborative for High-Performance Schools-Paints & Coatings, WELL Building Standard-VOC Restrictions, and Living Building Challenge–Healthy Interior Performance. Contact your Tnemec representative for more information.
