180 Degree Cure Black Matte Wheel Hub Powder Coating

Product Description

180 Degree Cure Wheel Hub Powder Coating, Black Matte Wheel Powder Coating
Introduction
Traditional paint contains organic solvents (VOCs) that are harmful to the environment. The powder coating does not contain any organic solvent and is a powdery substance with the advantage of zero VOC emission, and is one of the best choices to replace traditional paint. In addition, as countries pay more and more attention to environmental protection, powder coating is one of the future development trends in the coatings industry.
In the field of automotive, the wheelbase powder coating changes from the traditional 4 coats to 3 coats, canceling the base paint and using the base powder that integrates the bottom surface, which has become a new development direction. With the use of this process, the zero VOC characteristics of powder coatings can reduce VOC emissions by about 20% during the entire coating process, reduce coating processes, increase efficiency, and increase yield.
The wheelbase powder coating developed by KINTE has high leveling and good air permeability. It is suitable for curing at 180°C, which can greatly reduce the energy consumption and production cost of manufacturers. This product has good physical properties and chemical resistance and can meet the requirements of various wheel manufacturers for high leveling, and low baking temperatures, good chemical resistance, and excellent physical properties.
Key Features:
1. Better scratch resistance. The surface of the aluminum alloy wheel hub is mostly a rough casting surface. Because the powder is solvent-free, it shows good "filling and concealing properties", and is applied to the first coating of the wheel hub to cover surface defects.
2. Better stone resistance. Because it does not contain solvents, powder coatings are not easy to sag, and it is easy to achieve "single-layer high film thickness". Compared with the complex multi-coat liquid paint process, the single-layer powder primer shows better stone resistance performance.
Application Field:
A range of automotive wheel hubs for different requirements and coating characteristics
