Designed to solve the pain point of slow drying in vehicle repair, especially in low-temperature winter conditions, this clear coat combines international advanced coating technology with practical application needs of the automotive service industry. It realizes ultra-fast curing while maintaining superior gloss and film performance, greatly improving the turnover efficiency of vehicle repair orders for bulk users. Compatible with Zuotong’s 1K basecoat and other sanded, fully dried paint substrates, it is a one-stop solution for high-efficiency automotive clear coat application in large-scale repair projects.
The ZTC878 clear coat features a specially formulated acrylic polyurethane system that achieves industry-leading drying speed. At room temperature (25℃), it reaches dust-free status in 15-20 minutes and is polishable in just 1.5-2 hours; with low-temperature baking (60℃), polishing can be done in 15-25 minutes. Matched with ZTH878 low-temperature hardener (for <15℃) and ZTH868 normal-temperature hardener (for 15-25℃), it adapts to different regional and seasonal temperature changes, ensuring fast delivery of repair vehicles even in winter.
With excellent gloss retention and color stability, the clear coat forms a high-brightness, smooth film with outstanding leveling effect, eliminating orange peel and pinhole defects common in fast-drying coatings. It maintains long-term luster and anti-aging performance for automotive paint surfaces, meeting the high aesthetic requirements of 4S shops and high-end repair facilities for finished vehicle coatings.
Suitable for various automotive paint substrates after proper treatment, it supports both air-drying and low-temperature baking construction. No professional high-temperature baking equipment is required, reducing the hardware investment of coating enterprises. The simple mixing ratio and spray process lower the operational threshold for construction teams, ensuring consistent coating quality in large-batch repair projects.
The cured paint film has strong resistance to scratch, acid rain and ultraviolet rays. For minor construction defects such as dust spots and sagging, it can be wet-sanded with 1200#-2000# sandpaper and polished to restore the perfect finish, reducing the rework rate and improving production efficiency for B-end users.
