This instrument is designed and manufactured according to the standard of ISO2409-1992, and is applicable to GB/T9286-98, BS 3900 E6.
The instrument draw the grid of a certain size by a certain specification of the tools by using the uniform force, cut and penetrate the coating to be a grid lattice graphics, to evaluate the adhesion of coating on the substrate through the assessment of the full extent of the grid. There are six classes of grid lattice graphics, the assessment of coating separation from the substrate resistance is showing as different classes.
It is widely used to evaluate the adhesion of various coatings. It is not only to be used in the laboratory, can also be used under various conditions of the construction site.
