EPISODE 10 — Why Metallic Colors Are Difficult to Control?

Описание: Metallic automotive colors are among the most challenging systems in OEM paint shops due to their extreme sensitivity to flake orientation, solvent evaporation, rheology evolution, and spray application conditions. In this episode, we explain why metallic basecoats behave differently from solid colors and how small formulation or process changes can lead to major appearance failures.

The discussion covers metallic flake orientation mechanisms, solvent-driven flow behavior, and the influence of rheology on flop, brightness, and sparkle uniformity. Differences between laboratory panels and full vehicle bodies are highlighted to show why metallic colors often pass lab evaluation but fail during OEM appearance validation.

This episode is essential for coatings RD&I engineers, color development teams, and paint shop specialists working on metallic stability, appearance robustness, and OEM approval of solvent-based basecoats.

Post your technical questions in the comments related to metallic mottling, striping, flop mismatch, or lab-to-line metallic failures for future deep-dive discussions.
