Waterborne Construction Machinery Coatings – Recommended Monolith Resin System
Excavators, loaders, cranes and other construction machinery work outdoors in sun, rain, mud and abrasion, and their finish is part of the brand. A typical waterborne system pairs a 2K epoxy primer for corrosion protection with a 2K polyurethane topcoat for gloss, fullness and weathering.
This page summarizes the Monolith waterborne system recommended for construction machinery 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: fast drying, easy to be polished, salt spray resistance
- Top coat: high gloss and fullness, good weather resistance, high thickness of non-bubble film
Key performance needs
- Corrosion protection on steel parts and welded structures
- Primers that dry fast and sand easily for repair and line speed
- Topcoats with high gloss, fullness and long-term weather resistance
- Thick topcoat films that stay free of bubbles and pinholes
- Resistance to oils, fuels and cleaning agents

FAQ
Which waterborne system does Monolith recommend for construction machinery coatings?
The Monolith catalog recommends primer: EP137 + EH3510; topcoat: AH235 / AH239. “+” joins grades used together; “·” and “/” separate alternative options.
Which hardener is used with the epoxy primer for construction machinery coatings?
The recommended primer pairs a Monolith waterborne epoxy resin with the amine curing agent EH3510, 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 construction machinery coatings?
Besides the recommended system, the catalog application of these grades mentions this field: AH215, AH252, AH239H, AH32, AC523, WE33, WE34, WE44, WE49, WE55, PKA621, AH280.
How can I get the TDS, a sample or formulation support?
