Z9008 is a textured plastic primer formulated for automotive plastic components, including bumpers, SUV wheel arch trim, and other exterior plastic parts. The product delivers a black, textured finish that matches the appearance of many OEM plastic components, reducing the need for additional topcoat on parts where a textured black surface is the desired final appearance. Z9008 can be applied as either a two-component (2K) system using the recommended hardener or as a one-component (1K) system with thinner only, providing flexibility for different repair requirements. It is designed for use by professional refinishers in collision repair and commercial vehicle refinishing operations.
Z9008 produces a textured surface that replicates the grain pattern commonly found on automotive bumper covers and wheel arch moldings. The texture is controlled through spray technique, allowing operators to adjust the particle size to match the specific finish of the component being repaired. The black color is consistent across production batches, supporting uniform appearance on repaired sections.
Z9008 is formulated to adhere to a range of plastic substrates including PP, PA, PVC, and ABS, as well as to properly prepared metal surfaces. When used with the recommended ZTH393 hardener in the 2K configuration, the cured film provides improved mechanical properties compared with the 1K application method. The product is intended for professional application where surface preparation and mixing ratios are controlled.
The cured film of Z9008 is formulated to resist yellowing under UV exposure and to provide scratch resistance suitable for exterior automotive plastic components. Actual performance depends on correct mixing ratio, application technique, and curing conditions. For environments with high UV exposure, the 2K application with hardener is recommended.
Z9008 is compatible with the following substrates when properly prepared. First, plastic substrates including PP, PA, PVC, and ABS should be cleaned to remove contaminants and lightly abraded to promote adhesion. Second, metal substrates should be sanded with 600-grit sandpaper and cleaned thoroughly before application. All substrates must be free of grease, oil, silicone, mold release agents, and loose particles prior to coating. Inadequate surface preparation is a common cause of adhesion failure in plastic refinishing.
When used as a two-component system, mix Z9008 with ZTH393 Hardener and ZK103 Universal Thinner by weight in the ratio of 4:1:1.2-1.8. The thinner ratio may be adjusted within the specified range based on ambient temperature and desired application viscosity. After mixing, the pot life is approximately 4 hours at 25°C. Mixed material should not be used beyond this period as curing and film performance may be affected.
When used as a one-component system, mix Z9008 with ZK103 Universal Thinner by weight in the ratio of 1:0.5-0.8. The 1K method is suitable for applications where a hardener is not required or where simpler mixing is preferred. Note that the 1K configuration may offer reduced mechanical and chemical resistance compared with the 2K system.
Use a gravity-feed spray gun with a nozzle size of 1.5 mm to 1.7 mm and an air pressure of 1.8 bar to 2.5 bar. For textured application, use the lowest practical air pressure, a relatively high fluid output, and a slightly narrow spray pattern. Apply two mist coats. After the first mist coat, allow a flash-off time of 3 to 5 minutes, or until the sprayed particles on the surface are dry to the touch, before applying the second mist coat.
The following table provides drying time reference for Z9008:
Condition | Dust Free Time | Hard Drying |
|---|---|---|
Room Temp25℃) | 15 MIN | 1 HOUR |
Baked(60℃) | 10 MIN | 30 MIN |
Actual drying times may vary based on film thickness, ambient humidity, and ventilation.
The visible texture of the Z9008 finish is controlled by two primary variables: spray distance and fluid output. Regarding spray distance, a farther distance produces larger apparent particles because the droplets have more flight time to partially dry before impact, while a closer distance produces smaller particles because the droplets remain wetter and merge on the surface. Regarding fluid output, higher output delivers larger droplets that can produce a coarser texture, while lower output produces a finer mist and a smaller particle appearance. Operators should test on a scrap substrate to match the desired OEM texture before applying to the repair component.
Z9008 is packaged in 1-liter (1 kg) cans, with 12 cans per case. Store in a cool, dry, ventilated area away from direct sunlight and ignition sources. The shelf life is 2 years in unopened original packaging. Once opened, keep containers tightly sealed and use within a reasonable period. Hardener and thinner should be stored separately according to their respective storage instructions.
Z9008 is for professional use only. Operators should wear appropriate personal protective equipment, including chemical-resistant gloves, safety goggles, and a respirator suitable for isocyanate-containing products when using the 2K configuration with hardener. Fire prevention measures must be observed during use and storage. Keep out of reach of children. Consult the Safety Data Sheet (SDS) for detailed hazard information, handling instructions, and first-aid measures.
The 2K method uses ZTH393 Hardener and provides improved mechanical properties, chemical resistance, and durability. The 1K method uses thinner only and offers simpler mixing with no hardener-imposed pot life, but may have reduced performance. The 2K system has a pot life of approximately 4 hours at 25°C after mixing.
Z9008 is compatible with PP, PA, PVC, and ABS plastics, as well as metal substrates sanded with 600-grit sandpaper. All surfaces must be properly cleaned and prepared before application.
The texture is controlled by spray technique, primarily spray distance and fluid output. Operators should use low air pressure, relatively high fluid output, and a narrow spray pattern, applying two mist coats with a 3 to 5 minute flash-off between coats.
When mixed as a 2K system with hardener, the pot life is approximately 4 hours at 25°C. The 1K mixture with thinner only does not have a hardener-imposed pot life, but should be used promptly for best results.
