100-grid test
Project introduction
The 100-grid test is used to evenly mark out squares of a certain size, and evaluate the degree of adhesion of the coating to the substrate by evaluating the integrity of the coating in the squares, expressed in "grades". It is mainly used to determine the adhesion of organic coatings by the cross-grid method. It is not only suitable for laboratories, but also for construction sites under various conditions. Generally speaking, it is a tool for testing the adhesion of the test object after painting. According to the Japanese Industrial Standards (JIS), it is divided into 1 to 5 grades. The higher the grade, the stricter the requirements. When the customer specification requires the 5th grade, it means that there must be no shedding.
Test method
According to the Japanese Industrial Standards (JIS), it is divided into 1 to 5 grades. The higher the grade, the stricter the requirements. When the customer specification requires the 5th grade, it means that there must be no shedding.
About the test method of cutting with a hundred grids and using adhesive tape: The width of the blade is about 10mm~12mm, and the interval is 1mm~1.2mm, with a total of 10 grids. When cutting straight lines, 10 straight lines with the same interval will appear. Cutting vertically from the straight line marks will form a 10*10 square of 100 grids. When the hundred grid knife is cut, it should cut to the bottom material, and it should not only cut on the paint, otherwise the test will not be valid.
After the hundred grid knife is cut, it is necessary to use the adhesive tape to test whether it will fall off. First, stick the tape to the hundred grid position, press it down with your fingers to attach it tightly, and then tear the tape off with a momentary force to visually see if the paint on the material has fallen off. In addition, not just any kind of tape can be used. According to the JIS standard, the brand and model must be specified. For example, 3M's Transparent Tape 600 has a width of 3/4 inch and two lengths of 1296 inches and 2592 inches.
The adhesion performance of the product surface coating or ink is verified by the cross-cross method or tape method, which is used to verify the surface treatment process of the product.
