Coating film scratch test paper

The coating film scraping sample paper is a specialized paper material with a smooth surface, used for scraping and preparing samples of coatings and inks. The principle involves evenly spreading the coating on the paper to form a standardized thickness film layer. Its purpose is to provide a uniform substrate for testing properties such as color, hiding power, and leveling. It is applied in laboratory quality control and product comparisons.
Selection
When selecting, ensure consistent paper whiteness to avoid color differences, surface smoothness to affect coating uniformity, uniform thickness to guarantee scraping stability, ink absorption matching with the material to be tested, size compliance with the scraper specifications, and paper strength to prevent tearing during scraping. Choose the corresponding model based on the testing requirements.
