Automotive Clear Coat Additive
report_problem Problem Statement
Automotive clear coats use melamine-formaldehyde or isocyanate crosslinkers cured at 130-140°C to achieve the hardness, gloss, and weatherability required for exterior automotive applications. Melamine crosslinkers release formaldehyde during cure and service life, while isocyanates pose severe occupational health risks. A bio-based crosslinker using naturally-derived compounds could eliminate formaldehyde emissions from automotive paint lines and finished vehicles.
