WBX Air Cap – What Makes It Stand Out?
Superior Spray Pattern & Atomization
-
The WBX air cap is specially engineered for waterborne basecoats and HS clearcoats, providing superior atomization and control.
-
Its design achieves a long, flat fan pattern that delivers even overlap—crucial for avoiding mottling in basecoats and ensuring a smooth, consistent laydown on clears.
Consistency in Droplet Size
-
The WBX cap delivers uniform droplet size, which is essential for consistency in color reproduction and finish quality—especially important with modern materials.
