Series 90-98
Tneme-Zinc
Generic Type
Ethyl Silicate Inorganic Zinc-Rich
Common Usage
Self-curing, corrosion-resistant steel or ductile iron primer with tenacious bonding and abrasion resistance qualities. Its galvanic action resists undercutting. Excellent stand alone performance in high temperature or long-term atmospheric exposure. Finish with specialized topcoats to improve aesthetics, increase long-term performance or protect the primer from attack in aggressive exposures.
Special Qualifications
Zinc content surpasses the requirements of SSPC-PS 12.00 and ISO 8179-Part 2.
Series 90-98 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 0.005 inches (0.13 mm).

Theoretical Coverage
1,123 mil sq ft/gal (27.5 m²/L at 25 microns). See APPLICATION for coverage rates.
Volume Solids
70.0 ± 2.0% (practical)
Number of Components
Two: Part A and Part B
Recommended DFT
2.0 to 3.5 mils (50 to 90 microns) per coat.
Note: A minimum of 3.5 mils (90 microns) DFT is required to meet the qualifications of ISO 8179 Part 2. Note: Series 90-98 can be applied in one, high-build coat up to 6.0 mils (150 microns) DFT when left untopcoated.
Curing Time
| Temperature (50% Relative Humidity) | To Handle | To Recoat |
|---|---|---|
| 75°F (24°C) | 1 hour | 16 hours |
| 0°F (-18°C) | — | 7 days minimum |
Moisture is required to achieve proper cure. Curing time will vary with temperature and humidity. At relative humidities below 30%, it may be necessary to gently spray the coated surface with water to achieve proper cure and to minimize recoat time. Consult your Tnemec representative for specific recommendations.
