High-Adhesion Fiberglass Tank Coatings for Protection

The purpose of FRP coating is to protect the fiberglass tank structure from chemical attack, abrasion, moisture migration, and corrosion-barrier breakdown. In storage tanks, the coating or lining acts as the primary shield between the stored product and the structural laminate. A properly selected coating can extend service life, prevent weeping, and reduce the likelihood of costly tank replacement.

A coating should be evaluated when inspections reveal spidering, disbondment, abrasion wear, emulsification, low Barcol hardness, capillary migration, or evidence that the stored product has moved beneath the corrosion coat. Facilities also consider relining when chemistry, concentration, or operating temperature changes. Early restoration can turn a potential tank replacement into a planned maintenance project.

American Fiberglass Tank Repair uses custom-blended isophthalic and terephthalic polyester, vinylester, and epoxy resins, along with more than 45 fiberglass mat, chopped strand, Nexus, Harlar, and carbon veil laminates. The selected system is matched to the stored chemical, operating temperature, substrate condition, and required corrosion resistance for long-term performance.

Yes. Protective systems can be engineered for aggressive chemistries such as sodium hypochlorite, sodium hydroxide, ferric chloride, hydrochloric acid, and similar caustic or acidic products. Resin, veil, and laminate selections are based on chemical compatibility, concentration, temperature, and the tank’s existing FRP construction, helping restore safe storage capability.

Project duration depends on tank size, condition, access, chemistry, cure requirements, and whether nozzle modifications or structural repairs are included. AFTR schedules around customer operations, including shutdowns, nights, and weekends when needed. FRP tanker trailer relining is often completed in about two weeks at dedicated facilities, while field tank projects are planned around operational constraints.

Yes. Inspection is a critical first step. FTPI-certified inspectors and composite engineers can evaluate the interior corrosion coat, structural body, exterior shell, and nozzle interfaces. Testing may include visual review, ultrasonic methods, laser measurement, high-intensity backlight testing, and hardness checks. Findings guide the coating specification and repair scope.

In many cases, yes. Relining or coating restoration can recover tanks that would otherwise be condemned, especially when damage is limited to the corrosion barrier or repairable laminate areas. By restoring protective performance and adapting tanks to current service conditions, coating work often saves capital expense and avoids the long lead times of new FRP vessels.

Yes. Emergency FRP services are available for impact damage, tipped tanks, compromised linings, and other urgent incidents. Field crews can mobilize with Service-Pack containers stocked with resins, mat, and veil laminates, allowing repair work to begin quickly on arrival. Emergency response is available across all 50 U.S. states, Canada, and select international locations.
