Spray test card paper

Spray test cards are specialized papers used to evaluate the effectiveness of paint spraying, featuring surfaces specially treated to simulate actual substrates. The principle relies on the paper's absorption and color-revealing properties of the coating. By observing the uniformity of coverage, leveling, and color performance after spraying, the quality of the paint can be assessed. Their purpose is to quickly test the stability of the spraying process and the adaptability of the paint, making them applicable in paint production, spray line debugging, and quality control processes.
Selection
When selecting spray test cards, it is essential to match the surface characteristics of the actual substrate being sprayed, considering the relationship between paper weight and paint absorption. Pay attention to the correlation between paper whiteness and coating color development, and test its resistance to penetration. Ensure paper flatness to avoid distortion in testing, and choose the appropriate specifications based on the type of coating. Validate compatibility through small-batch trials to ensure the test results accurately reflect real-world conditions.
