Epoxy-Coated Carbon Steel Tanks

Thompson Tank’s epoxy coated tanks using the OptiBond process are becoming the standard for epoxy durability, corrosion resistance, UV breakdown and abrasion. We understand that the process by which a coating is applied is as important as the coating itself.

Benefits of Factory-Applied Coatings

Coatings applied in the environmentally controlled manufacturing facility and cured at a controlled temperature under strict process controls:

  • Eliminates the weather factors incurred when applying a coating in the field after constructing a welded tank. With factory-applied coatings there is no waiting for the weather to be within specific parameters in order to apply the coatings and trust in the environmental conditions to properly cure the coating.
  • Each step in our factory-applied coating process can be carefully monitored so that inconsistencies in the coating can be detected in the earliest possible stage of the process prior to tank construction fully applying the coating.
  • Completion of the tank can be performed in as much as 1/3 the time as alternative materials and methods. On site delays due to weather are greatly eliminated, service can commence earlier and ROI begins sooner.
  • The OptiBond™ Coating System

    Thompson Tank utilizes proprietary coating technology that provides maximum corrosion resistance and long tank life. Our experience has led to continuous technology and process improvements. The result is the finest epoxy coating available in the liquid tank industry. The OptiBond™ coating system is derived from years of in-field experience and performance data.


    Stage 1:

  • Parts are degreased and rinsed.
  • Precisely controlled hot air drying and pre-heating at optimum temperature for precision coating process
  • Stage 2:

  • Parts surfaces are blasted with engineered grit material.
  • Rugged 3-D surface topography is created for better powder coating performance.
  • A high velocity air curtain removes residual particulate.

    Stage 3:


    • arts are powder coated in our proprietary Trico Bond EP electrostatic booth with precise environmental controls.
    • Parts are cured at controlled temperature to maximize the cross-link bond of the epoxy particles.

    Stage 4:

  • Uniquely engineered polyurethane topcoat is applied for UV protection on the exterior surfaces for extra durability and longevity.
  • Sheets are cured at controlled temperature, yielding the final product.

    Parts are subjected to a rigorous quality control evaluation with a high voltage defect testing procedure. This will identify any holidays, inclusions and thin areas in the coating. No other company has a higher process and quality control standard.
