Series 90E-92


Generic Type

Ethyl Silicate Inorganic Zinc-Rich

Common Usage

Self-curing, primer/finish 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

Series 90E-92 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.

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. Ventilation: When used as a tank lining or in enclosed areas, provide adequate ventilation during application and cure. Reference ventilation guidelines contained in the latest edition of AWWA D 102.
