Crosslinking and Mechanical Characterization of Hydroxyl‐Terminated Caprolactone‐Modified (Meth)acrylic Clearcoats for Automotive Applications
Two‐component polyurethane (2K PU) clearcoats are widely used in automotive applications owing to their mechanical robustness, chemical resistance, and environmental stability. In original equipment manufacturing coating systems, hydroxyl‐functional polyols react with polyisocyanate crosslinkers to form dense ureth...
