In high-end finishing (e.g., premium automotive or specialized component coating), the application involves multiple layers—primer, basecoat (color), and clearcoat—each with precise thickness and flash-off timing requirements. The Multi-Layer Coating Robot is essential for managing this complexity.
The robot's controller manages the entire stack-up:
Process Coordination: It ensures the timing between layers is exactly right for proper adhesion, preventing defects like solvent pop or delamination.
Total Thickness Control: The robot precisely controls the film build of each layer, ensuring the final total film thickness is within tolerance without exceeding material limits.
Dedicated Tools: Robots can automatically switch between different atomizers or fluid delivery systems optimized for the viscosity of primer, basecoat, and clearcoat respectively.
