Waterborne Container Coatings – Recommended Monolith Resin System
Shipping containers are steel structures that spend their service life outdoors, at sea and in humid, salt-laden air, and they are coated on high-throughput production lines. Waterborne epoxy primers let container plants cut solvent emissions while keeping the corrosion protection of the exterior zinc-rich primer and the interior (PS) coating.
This page summarizes the Monolith waterborne system recommended for container 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
| Primer | EP138 + EH3512 / EH3507 · EP137 + EH3512 |
|---|---|
| Topcoat | Not specified in the catalog — ask our engineers |
“+” joins grades used together; “·” and “/” separate alternative options. Final selection depends on your substrate, process and specification.
Field-proven highlights
- Zinc-rich: excellent anti-sinking performance
- Easy to add water to change phase
- Excellent resistance to moisture and heat
- PS interior: good anti-sagging, silicon membrane bubble, good salt spray resistance
Key performance needs
- Corrosion protection for steel in marine and humid environments
- A stable zinc-rich primer: zinc powder that stays dispersed and does not settle hard
- Fast drying and handling to keep pace with the production line
- Interior coatings that tolerate moisture, condensation and heat during transport
- Good sag resistance on vertical panels and corrugated walls
Monolith grades for container coatings
| Grade | Type | Catalog application | Listed as |
|---|---|---|---|
| EP138 | Self-emulsifying epoxy | Zinc-rich primer | Recommended system |
| EH3512 | Modified amine adduct | Universal 2K hardener | Recommended system |
| EH3507 | Modified amine adduct | Container / rail primer | Recommended system |
| EP137 | Epoxy dispersion | Container interior (PS) coatings | Recommended system |
| EH3502 | Modified polyamide | Container interior coatings | Catalog application |
| AH239H | Acrylic dispersion | W/W technology, construction machinery, container | Catalog application |
All parameters are for reference and based on the COA at the time of shipment.

FAQ
Which waterborne system does Monolith recommend for container coatings?
The Monolith catalog recommends primer: EP138 + EH3512 / EH3507 · EP137 + EH3512. No dedicated topcoat is listed for this field; ask our engineers for a topcoat matched to your specification. “+” joins grades used together; “·” and “/” separate alternative options.
Which hardener is used with the epoxy primer for container coatings?
The recommended primer pairs a Monolith waterborne epoxy resin with the amine curing agents EH3512 / EH3507, 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 container coatings?
Besides the recommended system, the catalog application of these grades mentions this field: EH3502, AH239H.
How can I get the TDS, a sample or formulation support?
