Zuotong ZT9142
A bright-red repair is unforgiving. Uneven coverage, patchy color, dry spray, inconsistent gloss or poor curing can be visible immediately, especially on large panels and strong solid colors.
Zuotong ZT9142 Bright Red 2K Paint is designed for body shops that need a stable, direct-gloss solid-color system for everyday automotive refinishing. It is a two-component acrylic polyurethane coating that is mixed with the matching ZTH828 hardener and ZK301 thinner before spraying.
After proper mixing and application, ZT9142 forms a bright red, glossy and durable finish. For standard solid-color work, the system is applied as a direct-gloss topcoat, so an additional clear coat is normally not required.
This makes it a practical choice for panel repair, bumper repainting, commercial vehicle work, used-car refurbishment and full vehicle color changes.
| Common Workshop Issue | How ZT9142 Helps |
|---|---|
| Too many coating steps for solid colors | Direct-gloss system normally eliminates a separate clear coat step |
| Difficulty working in different seasons | Dedicated K, B and M hardener/thinner combinations support temperature matching |
| Bright red color looks thin or weak | 2–3 controlled thin coats build a full 40–60 μm coating film |
| Paint dries too fast in hot weather | Match ZTH828M and ZK301M for improved application control |
| Cold-weather repair takes too long | ZTH828K and ZK301K are available for low-temperature conditions |
| Plastic bumper paint cracking | Use correct plastic primer and a compatible flex additive where required |
| Repeated color mixing is inconsistent | Thorough stirring supports stable pigment distribution and repeatable formulation |
For metallic and pearl finishes, a clear coat is necessary to provide gloss and protection. But for many solid-color repair jobs, a properly formulated 2K acrylic polyurethane direct-gloss paint can complete the color and gloss layer in one coating system.

Bright Red Direct Gloss FinishThis workflow can help workshops:
ZT9142 is built on an acrylic polyurethane coating system and designed to work with ZTH828 series hardeners. The crosslinked film supports weather resistance, outdoor durability, mechanical strength and resistance to ordinary automotive service conditions.
The product provides a clean, vivid bright-red appearance. It is suitable for customers looking for a solid red finish with practical gloss and a full visual effect.
The volume ratio is easy to teach and easy to repeat:
2 Parts ZT9142 Paint
1 Part ZTH828 Hardener
0.2–0.4 Part ZK301 ThinnerCompared with percentage-style formulas, this reduces calculation work when technicians mix small repair quantities.
Use the corresponding hardener and thinner according to workshop temperature:
At 25°C, the low-temperature system provides approximately 2 hours of pot life, while normal/high-temperature hardener options provide approximately 3 hours. This gives technicians enough operating time for multiple panels or continuous repair work.
ZT9142 supports gravity-feed spray guns with 1.2–1.4 mm nozzle sizes, rather than requiring one fixed nozzle specification.
It is applied over properly sanded primer surfacer and supports repair work involving metal panels, plastic parts and thermoplastic painted surfaces when the correct pretreatment process is followed.
Use ambient drying when no bake booth is available, or use 60°C bake drying to accelerate handling and polishing time.
ZT9142 can serve as a bright-red solid-color component in a compatible color mixing system. Stir thoroughly before use to maintain pigment uniformity and formula repeatability.
From small panel repairs to full repainting and plastic bumper refinishing, ZT9142 helps workshops cover a wider range of solid-color jobs with one coordinated material system.
Suitable for repaired doors, fenders, hoods, trunk lids and quarter panels after primer surfacer preparation. Apply controlled thin coats to restore a consistent bright-red direct-gloss surface.
For vehicles with faded, scratched or damaged solid-red paintwork, ZT9142 offers an efficient direct-gloss solution for exterior refinishing.
ZT9142 can be used for full body repainting where a bright red solid-color finish is required. Use the appropriate seasonal hardener and thinner for stable application over larger panel areas.
For bumpers, mirror caps and plastic exterior components, use a compatible plastic primer. Add flex additive when specified by the coating process to improve flexibility.
When repainting a properly prepared thermoplastic paint surface, use controlled thin coats and allow the stated flash-off time between coats to reduce the risk of solvent attack.
Paint mixing centers and workshops with color-mixing capability can use ZT9142 as a bright-red component for related solid red formulas.

| Substrate Coverage | Compatible with metal repair areas, plastic parts and thermoplastic paint surfaces using correct plastic primer/flex additive procedures | Often mainly specified for old paint and primer surfacer; plastic process may not be clearly supported | Helps body shops handle bumper and exterior plastic repair with a clearer system approach |
| Resin and Curing System | Acrylic polyurethane coating with HDI-trimer hardener compatibility | May only state general hardness and gloss performance | Supports stronger weather resistance, UV durability and corrosion-resistance capability |
| Spray Gun Compatibility | 1.2–1.4 mm nozzle range | Often limited to a fixed 1.3 mm nozzle recommendation | Compatible with more mainstream gravity spray guns, reducing the need for dedicated equipment |
| Repair Service Scope | Mid- to high-end refinishing, full repaint, metal repair, plastic repair and thermoplastic surface repainting | Usually conventional old-paint repair and primer-surfacer application | Enables more job types and greater revenue opportunities from one color system |
| Climate Matching | Dedicated K/B/M hardeners and thinners for cold, normal and hot conditions | Seasonal system may be less complete or less clearly defined | More stable year-round operation across different local climates |
Comparison reflects common market positioning and typical published product information. Actual competitor performance varies according to brand, technical data sheet, material selection and workshop conditions.
ZT9142 should be applied over a properly prepared primer surfacer.
Before adding hardener or thinner, stir ZT9142 thoroughly. This is especially important when using the product in color mixing operations because settled pigment can affect color consistency.
