LongGreen 7210 is a high-performance external tire paint designed specifically for the tire industry. It’s a black, low-viscosity suspension, made to fit the needs of green tire production. You can use it right out of the container—just apply it directly to the outer surface of green tires. This not only helps reduce product defects, but also boosts production efficiency and cuts down on costs. It works well in promoting adhesion, bleeding air, aiding rubber flow, preventing mold fouling, and staying stable during storage, making it a great auxiliary material for green tire manufacturing.
Here’s how it works: it optimizes green tire production and ensures product quality. When you spray it on green tires, it forms a uniform coating. This coating strengthens the adhesion between rubber layers at the splice points, effectively preventing joint separation. Joint separation is a common issue that leads to serious tire defects like delamination, so this feature helps enhance the tire’s structural integrity and lays a solid foundation for high-quality finished tires.
One of the biggest advantages of LongGreen 7210 is its ability to bleed air efficiently and improve rubber flow. During the vulcanization process, trapped air inside green tires can cause defects like bubbles or voids, which hurt the tire’s performance and service life. This product lets that trapped air escape smoothly, and it also helps rubber flow better, ensuring the mold is filled evenly. These features reduce defects, increase the qualification rate of finished tires, and cut down on production waste.
Mold fouling is a big problem in tire production—it affects the tire’s surface quality and shortens the mold’s service life. LongGreen 7210 rarely causes mold fouling; its special formula minimizes rubber residue sticking to the mold. This extends the mold’s life and reduces the downtime needed for mold maintenance. In addition, its custom dispersion system keeps it stable: if stored properly, it won’t separate or settle, so its performance stays consistent every time you use it.
Using LongGreen 7210 also brings significant economic benefits. Since it’s ready to use, you don’t need to do any complicated preparation before application—saving both time and labor. It’s low-consumption, so it reduces material costs, and it dries quickly, which speeds up the production cycle and increases output. For tire manufacturers, this makes it a very cost-effective choice.
The dried coating also adds practical value: it forms a light grey film that contrasts clearly with the tire’s color codes and barcodes. This makes the identification marks easy to read, which helps with product tracking, quality control, and inventory management. In turn, this improves efficiency throughout the entire production and supply chain.
To get the best performance out of the product, you need to operate it correctly. It’s best to apply it with an air-atomizing gun to ensure uniform coverage. Before using it for the first time, give it a quick mix—either light stirring or rolling the drum—to keep the suspension consistent. This way, its performance stays reliable during the entire application process.
Following the recommended spraying conditions will maximize its performance: use stainless steel nozzles (0.8–1.5 mm) for durability, set the material pressure to 1.5–3.5 bar, and the air atomizing pressure to 2.5–6.0 bar. These settings turn the product into fine droplets, creating a uniform, thin coating—something that’s essential for achieving the desired adhesion and performance.
Proper maintenance during production breaks is also important. If there’s a long break in production, clean the spray guns with gasoline, solvent, or high-pressure water. This prevents the dried product from blocking the nozzles. Also, make sure to tightly cover the containers and drums to avoid water loss—this keeps the suspension stable and prevents it from separating or settling.
LongGreen 7210 is only used in the tire industry, serving as a key auxiliary material for green tire production. Its versatile performance fits different tire types—passenger cars, trucks, and specialized tires—and different production scales. It consistently delivers reliable results, helping manufacturers improve quality, reduce costs, and enhance their competitiveness.
In short, LongGreen 7210 is a high-quality, efficient, and cost-effective external tire paint that solves key problems in green tire production. Its black, low-viscosity formula, strong adhesion, efficient air bleeding, low mold fouling, good stability, and easy operation make it an essential product for tire manufacturers. Using it helps reduce defects, improve efficiency, cut costs, and produce high-quality tires that meet market demands.
