Waterborne Steel Pipe Coatings – Recommended Monolith Resin System
Steel pipes and tubes are coated on fast production lines, and the coating has to dry quickly for stacking and transport while protecting the steel from rust in storage. Waterborne epoxy ester and modified epoxy dispersions are used for these coatings with low aromatic solvent content.
This page summarizes the Monolith waterborne system recommended for steel pipe 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
- Low benzene series content
- Good water resistance
- Fast drying
Key performance needs
- Fast drying for line speed, stacking and handling
- Rust protection during storage and transport
- Good water resistance
- Low content of benzene-series (aromatic) solvents
- Suitability for dip, flow or spray application on the line

FAQ
Which waterborne system does Monolith recommend for steel pipe coatings?
The Monolith catalog recommends primer: WE33 · WE44 · WE55; topcoat: WE33 · WE44 · WE55. “+” joins grades used together; “·” and “/” separate alternative options.
Can the same grade be used as primer and topcoat for steel pipe coatings?
Yes, the Monolith catalog lists the same grades (WE33 · WE44 · WE55) for both primer and topcoat in steel pipe coatings. Confirm the coating structure and film build for your specification with our engineers.
Which other Monolith grades are listed for steel pipe coatings?
Besides the recommended system, the catalog application of these grades mentions this field: AK9506, WE34, WE49.
How can I get the TDS, a sample or formulation support?
Use the Request TDS / Sample form or email martin@monolithchem.com with your application, substrate and target performance. Monolith application engineers will recommend grades and send the technical data sheets.
