Waterborne Petrochemical Storage Tank Coatings – Recommended Monolith Resin System
Storage tanks in refineries, chemical parks and depots are large steel surfaces exposed to weather and to chemical splash and fumes. A waterborne system protects the tank shell with a 2K epoxy primer and finishes it with a chemical- and weather-resistant 2K polyurethane topcoat.
This page summarizes the Monolith waterborne system recommended for petrochemical storage tank coatings in our catalog, the grades whose catalog application lists this field, and the performance points to check when you select a system.
Recommended Monolith system
“+” joins grades used together; “·” and “/” separate alternative options. Final selection depends on your substrate, process and specification.
Field-proven highlights
- Primer: good salt spray resistance, putty resistance, excellent adhesion
- Top coat: acid and alkali resistance, aging resistance
Key performance needs
- Strong adhesion and corrosion protection on large steel surfaces
- Compatibility with putty and repair materials
- Topcoat resistance to acids, alkalis and chemical splash
- Long-term resistance to UV and weathering
- Application properties that suit large structures coated on site

FAQ
Which waterborne system does Monolith recommend for petrochemical storage tank coatings?
The Monolith catalog recommends primer: EP137 + EH3513; topcoat: AH239. “+” joins grades used together; “·” and “/” separate alternative options.
Which hardener is used with the epoxy primer for petrochemical storage tank coatings?
The recommended primer pairs a Monolith waterborne epoxy resin with the amine curing agent EH3513, as listed in the system above. Mixing ratios depend on the exact grades and formulation; request the TDS for the pair you plan to use.
Which other Monolith grades are listed for petrochemical storage tank coatings?
Besides the recommended system, the catalog application of these grades mentions this field: none beyond the recommended system.
How can I get the TDS, a sample or formulation support?
