For decades, exterior coating systems from Tnemec have extended service life of aboveground storage tanks in refineries, fuel terminals and chemical plants. Tnemec has built its reputation for advanced technologies that are industry-leading in both of performance and ease-of-application.

Exterior coatings are specially formulated to protect the outer shell of tanks, piping, and exposed structural steel against corrosion, abrasion, ultra-violet (UV) light degradation and weathering. Epoxies and aromatic zinc-rich urethanes can be topcoated with a variety of acrylic, polyurethane and fluorpolymer formulations to provide complete coating systems that offer excellent durability, colour and gloss retention and ease of maintenance.

Vessels holding hazardous materials require high-performance lining to protect the structure and its contents. Fighting corrosion from the inside out, Tnemec’s thick-film Tank Armour Lining technology is specially formulated as an interior coating for storage tanks in the oil and gas industry. The extra-durable epoxy linings provide chemical- and abrasion-resistance in the most challenging operating conditions.

Tank Armour’s 100 percent solids formulations allow a significant advantage for storage tank owners by providing a single-coat, quick-cure application process for rapid return to service with their high-build application characteristics and the ability to retain thickness over welds, seams and angles. Tank Armour is VOC-compliant and conforms to API 652.

To achieve the same barrier protection as Tank Armour, traditional linings must be applied in multiple coats adding labour costs and many extra days of costly downtime.

Tnemec’s thin-film Tneme-Liner, is a high-solids, cycloaliphatic amine-cured epoxy lining that meets and exceeds the performance of novolac epoxies in many chemical exposures. The selected cycloaliphatic curing agent in Tneme-Liner, reacted with the functionality of the epoxy, yields a tightly cross-linked bond resulting in outstanding chemical and corrosion resistance. This curing mechanism allows Tneme-Liner to resist a wide range of chemicals, sweet and sour crude oil, and finished fuels and solvents. Applications include refining, chemical processing, industrial waste treatment, secondary containment, pipeline production and process equipment, vessels and spool sections, and other severe service conditions. Tneme-Liner can also be used as a holding primer for large storage tanks when topcoating with select Tank Armour linings. Additionally, the linings meet the performance criteria requirements for MIL-PRF-4456F, a military specification for epoxy coating systems used to line jet fuel storage vessels.

Whether for storing and transporting fuel, or for chemical processing, Interior linings prevent early deterioration and downtime. Specially formulated thin-film and thick-film (100% solids) linings are applied using conventional airless spray or plural component equipment.

Floating roofs are complex structures and take into account many variables, including type of product stored, product temperature, flexing and typical weather/environmental conditions.

Tnemec offers immersion-grade, low-yellowing epoxies for the exterior of floating roofs. A typical coating system includes an aromatic zinc-rich urethane primer and a chemical resistant, high-build epoxy topcoat. This combination provides superior steel protection and a longer life expectancy thanks to the primer’s zinc protection combined with the low erosion and low chalk rate of the high-density, cross-linked epoxy topcoat.

Aerolon is designed to provide protection against condensation, corrosion under insulation (CUI), energy retention and ensure Personnel Protection & Worksite Safety by offering a safe-to-touch surface. Its applications are versatile, covering everything from (process) piping, storage tanks, pressure vessels, storage spheres, structural steel and heat exchangers/dryers.

A fluid-applied, single-component, easy-to-install solution which can be used used in new contstruction and maintenance, providing an alternative to conventional thermal insulation & jacketing in both cold and heated service, of up to 163 degrees Celsius, where CUI risks are most prevalent.

In harsh industries, especially oil, gas and power, protective coatings are used in many situations, but one particular need is the application of an abrasion resistant overcoat (ARO) on oil and gas transmission pipelines. These durable coatings are used to protect the standard fusion-bonded epoxy (FBE) coatings on pipes being installed via trenchless methods.

Limiting downtime and helping reduce labour and surface preparation costs, Tnemec’s surface-tolerant epoxy coatings allow projects to continue even when coating conditions are not perfect. These products are formulated for overcoating and adhering to the substrate when ideal surface preparation is not achievable.
