Paint and coating screening is a critical process in manufacturing, especially for automotive, aerospace and architectural coatings. The main purpose of paint and coating screening is to remove impurities and particles to ensure the quality of the final paint. Through screening, the particle size of the coating can be made uniform and the uniformity and gloss of the coating can be improved. In addition, screening can also help ensure that the viscosity and fluidity of the coating meet the requirements, thereby improving the coating effect.
Materials
Spray paint, magnetic pigments, non-magnetic pigments, epoxy powder coatings, polyester powder coatings, and acrylic powder coatings.
Application
Industry Standard
- The mesh size for coating in liquid form varies depending on the concentration and viscosity. When the concentration and viscosity are high, the preferred mesh size ranges from 60 to 100 mesh. On the other hand, when the concentration and viscosity are low, the mesh size typically falls between 200 and 400 mesh. Additionally, the industry-standard mesh sizes for spray painting and baking processes are 325 and 400 mesh.
- Similarly, in the realm of resin production, both liquid and powder forms require careful consideration of mesh size. For liquid resin, the mesh size ranges from 60 mesh to 250 mesh, with higher viscosity and concentration requiring a coarser mesh, and lower viscosity and concentration calling for a finer mesh.
- In the manufacturing of powder coating, the choice of mesh size is equally important. The raw material manufacturing process generally utilizes mesh numbers such as 100 mesh and 120 mesh, with a few instances of 150 mesh and 200 mesh. However, in the powder coating processing industry, where recycling after painting is common, smaller mesh sizes like 60 mesh, 80 mesh, and 100 mesh are typically used due to the smaller quantity involved.
