As a low-temperature fast-dry additive for automotive paint, it addresses the biggest pain point of clients in cold climates: slow curing that leads to extended vehicle turnaround times and reduced workshop productivity. Designed for seamless integration with all Zuotong 2K coating systems (and compatible with most industry-standard 2K products), it is a must-have additive for professional auto body shops, mobile repair services and bulk coating distributors looking to optimize their service efficiency.

This fast-dry agent for 2K clear coats drastically reduces dust-free and hard drying times of 2K coatings, cutting vehicle turnaround time for small repairs by up to 50%—a game-changer for busy repair shops and mobile refinishing services.
Tailored for 0-15℃ coating applications, it maintains consistent curing performance in cold workshop environments where standard 2K coatings struggle to dry, eliminating the need for expensive heated curing booths for minor touch-ups.
Engineered to work with hardeners (never a replacement), it preserves the original performance of 2K topcoats/clear coats—including gloss retention, scratch resistance and chemical resistance—avoiding the brittleness or peeling caused by inferior fast-dry additives.
With a simple cap-based dosage system, it requires no complex measuring tools, streamlining the mixing process for technicians. The liquid formulation blends seamlessly with pre-mixed 2K paints, ensuring uniform distribution and consistent curing across the entire coating surface.
