As a core auxiliary product in Zuotong’s Automotive Paint Plus+ series, this anti-blushing agent for spray painting is specially formulated to slow down the evaporation rate of automotive paints and extend the sealing time of paint film surfaces—an essential solution for large-area spraying projects such as automotive body refinishing, commercial vehicle coating, and industrial large-component painting. Designed exclusively for professional use, it is paired with Zuotong’s ZK300TM Extra Slow Thinner to eliminate blushing, fogging, and poor leveling caused by rapid solvent evaporation in hot and humid conditions (>30°C). For clients including automotive repair workshops, coating manufacturers, and industrial spraying enterprises, the ZF155 slow drying agent for automotive paint elevates coating quality, reduces rework rates, and ensures consistent, high-gloss paint film results even in challenging construction climates.

The specialized formulation directly targets paint film blushing caused by high temperature and high humidity, forming a stable evaporation layer on the paint film surface to prevent moisture condensation and ensure a smooth, defect-free finish—making it the best blush preventive agent for large-area spraying.
It precisely slows down the solvent evaporation rate of automotive paints without affecting the final curing speed, extending the paint film’s open time and sealing time. This allows sufficient leveling for large-area spraying, eliminating orange peel, pinholes, and uneven gloss caused by rapid drying.
By optimizing the paint’s flow performance, the ZF155 slow drying agent improves the atomization effect of spray guns, ensuring uniform paint deposition on complex surfaces (e.g., automotive body curves, industrial metal components). It enhances overall leveling, delivering a mirror-like finish that meets the high aesthetic standards of automotive and industrial coating.
Exclusively matched with Zuotong’s ZK300TM Extra Slow Thinner (10–30% addition ratio), it forms a synergistic system that avoids chemical incompatibility and ensures consistent performance—eliminating the risk of paint film failure caused by random thinner matching.
