Coatings Cross Hatch Adhesion Tester is a tool used to assess the adhesion of a coating to its substrate. It involves making a series of intersecting cuts in the coating to create a grid pattern. The adhesion is then evaluated by applying adhesive tape to the cut area and measuring the amount of coating removed.
Measuring the adhesion strength of coatings such as paint, glue, varnish etc., is necessary to ensure the coating has bonded well to the substrate and is performing satisfactory. A variety of adhesion testing methods are available to determine how well the coating is bonding to the solid substrate.
The Cross Hatch Test Method is widely used to assess the adhesion of paint coatings and provides an instant assessment of the quality of the bond to the substrate.
