Waterborne Automotive OEM Coatings – Recommended Monolith Resin System
Automotive OEM coating lines demand a demanding appearance, consistent quality and robust processing in waterborne basecoat and primer-surfacer (PS) layers. Waterborne acrylic emulsions combined with polyester dispersions are used to build these layers, including metallic effects.
This page summarizes the Monolith waterborne system recommended for automotive OEM 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
- Aluminum powder orientation is good
- Excellent roller distribution
- Good fullness/flexibility
Key performance needs
- Good aluminum flake orientation for metallic and effect colors
- Smooth, even film distribution
- Fullness and flexibility of the finished film
- Stable processing in automated spray and bake lines
- Compatibility between basecoat, PS coat and clearcoat layers
