2-Wet Monocoat System
Axalta’s 2-Wet Monocoat System for light vehicle OEMs combines the paint performance of a clearcoat-over-basecoat system with the productivity of a monocoat process. The process begins with a layer of 2-Wet primer followed by a no-heat, ambient flash. The vehicle is then coated with the 2-Wet Monocoat coating followed by a bake cycle. Coating applications are reduced from three to two and the number of drying steps from two to one. By removing steps in the painting process, the 2-Wet Monocoat System is designed to increase productivity with reduced energy use and paint shop footprint.
The desired monocoat appearance is achieved with a hyper-branched acrylic polymer formulated to provide high-quality appearance and durability. Formulation tools were also developed to match the full set of required attributes in combination with the wet primer layer. Advanced weathering tests have shown that paint applied with our 2-Wet Monocoat technology retains as much as 90 percent of its gloss after four years compared to one percent gloss retention for paint applied using a conventional monocoat process.
