Z9001R 1K Grey Plastic Primer is a single-component adhesion primer manufactured by ZUOTONG Chemical, specifically developed for polypropylene (PP) and PP-based composite substrates commonly found in automotive exterior and interior parts. The product is formulated to promote adhesion between non-polar plastic surfaces and subsequent topcoat layers, addressing a common challenge in automotive refinishing and industrial plastic component coating.
As a 1K air-drying system, Z9001R requires no isocyanate hardener and is mixed with ZK103 Universal Thinner at a defined weight ratio before spray application. The grey color provides a uniform base that assists in detecting film uniformity and coverage during the coating process. Each can has a net content of 1 liter (approximately 1 kilogram), and cases are packed with 12 cans per unit for bulk procurement by industrial clients and commercial coating operations.
Z9001R contains adhesion-promoting resins tailored for polypropylene surfaces. Properly cleaned PP substrates coated with Z9001R demonstrate improved intercoat adhesion compared with standard primers applied directly to untreated plastic. The primer is intended as a tie-coat layer and should be overcoated with a compatible topcoat system.
The product is supplied as a single-component concentrate that is reduced with ZK103 Universal Thinner at a weight ratio of 4 parts primer to 1 part thinner. This mixing format allows applicators to prepare only the volume needed for each job, reducing unused mixed material. The mixed material should be used promptly; if the pot life exceeds 1 hour, thorough re-stirring is required before continued use.
Z9001R delivers a fine, smooth film when applied according to the specified spray parameters. The drying schedule includes both ambient-temperature and forced-bake options, allowing flexibility for different production line setups. The grey tint enables visual inspection of film build and coverage on both light and dark plastic substrates.
Z9001R is designed for properly cleaned polypropylene (PP) and PP composite surfaces. The substrate must be free of mold release agents, grease, silicone, and other contaminants. Surface cleaning with a suitable plastic cleaner followed by a lint-free cloth is recommended before primer application.
Component | Mixing Ratio (by weight) |
|---|---|
Z9001R 1K Plastic Primer | 4 |
ZK103 Universal Thinner | 1 |
Mix 4 parts of Z9001R with 1 part of ZK103 Universal Thinner by weight. Stir thoroughly before and during application. If the prepared material stands for more than 1 hour, re-stir thoroughly before use.
Parameter | Specification |
|---|---|
Spray Gun Type | Gravity-feed |
Nozzle Size | 1.5 - 1.7 mm |
Air Pressure | 1.8 - 2.5 bar |
Application Method | 2 even coats |
Apply two even coats using a gravity-feed spray gun with a nozzle diameter of 1.5 to 1.7 mm and an air pressure setting of 1.8 to 2.5 bar. Excessive film build should be avoided, as it may compromise adhesion and extend drying time.
Drying Condition | Dust-free Time | Polishing Time |
|---|---|---|
Room Temp (25°C) | 10 MIN | 30 MIN |
Baked (60°C) | 5 MIN | 10 MIN |
At an ambient temperature of 25°C, the primer reaches a dust-free state in 10 minutes and can be polished after 30 minutes. Forced baking at 60°C reduces the dust-free time to 5 minutes and the polishing time to 10 minutes.
Z9001R is packaged in 1-liter metal cans, with 12 cans per case. Store the product in a cool, dry, and well-ventilated area, away from ignition sources and direct sunlight. Under recommended storage conditions, the shelf life is 2 years in unopened original containers.
This product is intended for professional use only. Operators must wear appropriate personal protective equipment, including chemical-resistant gloves, safety goggles, and an organic-vapor respirator. Fire precautions are required during storage and spray application due to flammable solvent content. Keep the material out of reach of children. Contact the supplier for technical data sheets and additional safety information.
Z9001R is formulated for properly cleaned polypropylene (PP) and PP-based composite surfaces. It is not intended for metal, wood, or other non-plastic substrates.
Mix Z9001R 1K Plastic Primer with ZK103 Universal Thinner at a weight ratio of 4:1 (4 parts primer to 1 part thinner).
The mixed material should be used promptly. If it stands for more than 1 hour, re-stir thoroughly before continuing application.
Use a gravity-feed spray gun with a nozzle size of 1.5-1.7 mm and an air pressure of 1.8-2.5 bar. Apply two even coats.
At 25°C room temperature, the dust-free time is 10 minutes and the polishing time is 30 minutes. When baked at 60°C, the dust-free time is 5 minutes and the polishing time is 10 minutes.
Each case contains 12 cans of 1 liter each.
