Reactivity and Curing Efficiency of Isocyanate Cross-linkers with Imidazole-Based Blocking Agents for Low-Temperature Curing of Automotive Clearcoats

Reactivity and Curing Efficiency of Isocyanate Cross-linkers with Imidazole-Based Blocking Agents for Low-Temperature Curing of Automotive Clearcoats

For the application of low-temperature curing on automotive clearcoats, isocyanate cross-linkers blocked with imidazole derivatives were newly synthesized. The effect of the alkyl groups in the imidazole derivatives on the deblocking behavior and curing kinetics was investigated. The free isocyanate...
