Product Details
✓The Coating hardness is a necessary indicator for quality certification in the coating manufacturing and coating application (coating table) industry. The pencil scratch method is a commonly used method for measuring the hardness of coatings.
✓The pencil hardness tester is suitable for testing the hardness of coating. The instrument can be used in the laboratory or on construction sites, and can be used to identify the hardness of coating in any direction.
✓The pencil hardness tester adopts mechanical measurement. Maintain a three point contact coating (two wheels, one pencil lead), with a 45 degree angle between the pencil and the test surface. Push the instrument to slide and use a pencil to draw the corresponding trajectory on the coating. The hardness value of the film can be determined in the variation of different pencil markings.
