Scraping card

A drawdown card is a tool used to test the hiding power of materials such as coatings and inks. The principle involves evenly applying the sample onto a black-and-white grid card and assessing the hiding performance by observing the extent to which the black and white squares are covered. Its function is to evaluate the hiding effect of materials, and it is applied in quality control within the coatings and ink industries.
Selection
When selecting a scratch card, consider the contrast of black and white grids, the durability of the card material, the size of the scratch groove matching sample requirements, ease of operation, and cost. Ensure the card surface is flat to avoid affecting test results, and choose the appropriate specification based on the actual application environment.
