Steel Storage Tank Protection Coatings and Linings

Superior Protection for Steel Tanks - 314.664.2230

Securing Steel TanksChemline supplies coatings and linings for both aboveground and underground steel storage tanks. Several products can be applied in one-coat, direct to metal (DTM) applications. To speed production and shipment, Chemline’s coatings cure to the touch within a few minutes or just a few hours.

Underground - Exterior Tank Protection

CHEMTHANE 2240 is a solvent free, tar-free, two component polyurethane coating. This product has a very short reaction time and is therefore spray applied using plural component spray equipment. You can apply this product directly to surface prepared steel. Unlimited film builds may be achieved in a single coat multi-pass application. Cured films are free of pores.

Chemthane 2240 demonstrates an excellent balance of flexibility, impact strength, abrasion resistance and corrosion resistance.

  • Complied with Standard UL-1746 Part I and Part IV
  • Extremely high toughness and impact resistance
  • 1:1 mixing ratio
  • Low temperature cure (down to 25F/-4C)
  • Fast set times

Aboveground - Exterior Tank Protection

For these applications, we recommend our conventional airless-applied, acrylic polyurethanes: CHEMTHANE 3107 and CHEMTHANE 3300.

  • High Solids, Low VOC
  • Direct to Metal (DTM) systems (Chemthane 3107)
  • Three coat (Chemzinc 100/Chemprime 3001/Chemthane 3300) Systems for aggressive environments
  • Fast Dry Times
  • Florida Weathering Data Available
  • Colors available

Internal Linings for Steel Tanks

Steel Tank LiningsCHEMLINER 4000 is a high Solids, novolac epoxy lining. This product is self-priming and is applied to steel surfaces. It has excellent chemical resistance against jet fuel, wastewater, seawater, salt brine, sulfide gas, acid solutions, strong alkali solutions and many solvents. The high cross-link density of the product makes it suitable for immersion service in aggressive environments. Consult CHEMLINE before specifying. CHEMLINER 4000 is easy to apply using a brush, roller, conventional or airless spray equipment. This product is applied in a minimum of two coats (white coat and gray coat).

  • High Solids (73% by volume)
  • 4:1 mix ratio
  • Two coat application
  • High chemical resistance for aggressive immersion environments
  • Excellent adhesion to steel


CHEMTHANE 4200PW (NSF/ANSI-61) is a solvent-free, two component polyurethane lining (1:1 spray ratio by volume). This product has a very short reaction time and is therefore spray applied using plural component spray equipment. Application of this product is made directly to surface prepared steel. Unlimited film builds may be achieved in a single coat multi-pass application. Once cured, Chemthane 4200PW forms a hard polymer film that demonstrates excellent adhesion. In addition, it is very resistant to abrasion, chemical attack, and cathodic disbondment.

 

  • Complied with Standard UL 2215 Internal Lining Standard for Oil Water Separators
  • Complied with AWWA C-222 
  • High Temp Resistance
