The Automotive Paint Thinner Series comprises a range of solvent reducers engineered specifically for Zuotong clear coats, intermediate coats, primers, and basecoats. Targeting automotive refinishing shops, fleet maintenance facilities, and industrial coating contractors, the series includes universal and high-performance formulations in fast, standard, and slow-drying variants. Each grade is calibrated to match specific Zuotong coating products and ambient temperature conditions, enabling consistent atomization, flow-out, and solvent release across different job sizes and climates.
Temperature-graded selection: K (fast), B (standard), and M (slow) variants correspond to ambient temperature ranges below 18°C, 18–30°C, and above 30°C respectively.
Dual formulation tiers: Universal thinners for intermediate and primer systems; high-performance thinners for 2K clear coats and topcoats with stronger solvency.
Application-scaled drying: Faster grades suit small-area spot repairs; slower grades accommodate large-panel and full-vehicle spraying where extended flow-out is required.
System-matched compatibility: Each thinner grade is designated for specific Zuotong coating products, reducing the risk of incompatibility and film defects.
Humidity adaptation: Compatible with ZF155 anti-blushing agent at 10–30% addition rates under high-humidity conditions.

Select the drying grade according to ambient workshop temperature. Use type K (fast-drying) thinner when the temperature is below 18°C. Use type B (standard-drying) thinner between 18°C and 30°C. Use type M (slow-drying) thinner when the temperature exceeds 30°C. For ambient temperatures above 35°C, ZK300TM extra-slow thinner may be used in appropriate quantities to replace ZK103M or ZTH301M.
For small-area spraying such as spot repairs and touch-up panels, select a relatively faster-drying thinner to minimize process wait time. For large-area or full-vehicle applications, select a relatively slower-drying thinner to allow sufficient flow-out and solvent release, reducing the risk of dry spray and orange peel.
In conditions of excessively high temperature or high humidity, add 10–30% of ZF155 anti-blushing agent to the thinner mixture to prevent moisture blush. Note that high-performance thinners (ZTH301 series) exhibit slightly stronger solvency than universal thinners (ZK103 series) and extra-slow thinners (ZK300TM). After opening, reseal the container immediately to prevent solvent evaporation and maintain formulation integrity.
The universal thinner series (ZK103K/B/M) is formulated for use with ZTC393 Golden Clear Coat as well as Zuotong intermediate coats and primer products. The high-performance thinner series (ZTH301K/B/M) is designed for ZTC919 and ZTC828 clear coats and Zuotong 2K topcoats. The ZK303K/B/M series is dedicated to Zuotong 1K basecoat colors. ZK300TM serves as an extra-slow option for extreme heat conditions across compatible systems. Always verify the recommended thinner for each specific coating product before mixing.
The Automotive Paint Thinner Series is available in two packaging configurations: 4 L cans packed 6 units per carton, and 5 L cans packed 4 units per carton. Store all containers in a cool, dry, and well-ventilated environment away from direct sunlight, heat sources, and open flames. The shelf life is 2 years from manufacture when stored in unopened original packaging. This product is for professional use only; operators must wear appropriate personal protective equipment and observe fire-prevention measures during handling and storage. Keep out of reach of children.
Use the ZK103 universal thinner series with ZTC393 clear coat, intermediate coats, and primers. Use the ZTH301 high-performance thinner series with ZTC919, ZTC828 clear coats, and 2K topcoats. High-performance thinners have slightly stronger solvency and are matched to the resin system of premium clear coats.
When workshop temperature is below 18°C, use type K (fast-drying) thinner. Between 18°C and 30°C, use type B (standard-drying). Above 30°C, use type M (slow-drying). For temperatures exceeding 35°C, consider ZK300TM extra-slow thinner.
Yes. In high-temperature or high-humidity conditions, add 10–30% of ZF155 anti-blushing agent to the thinner mixture. This addition helps prevent moisture condensation in the wet film during solvent evaporation.
