On May 4, 2026, industry authorities shared the cross-cut test technology, providing a standardized solution for evaluating the adhesion between coatings and substrates. Using a specialized tool, it cuts a 10×10 standard grid penetrating the coating to the substrate, peels with standard tape, and grades by peeling area. It’s simple to operate with intuitive results, suitable for testing thin adhesive layers (≤120μm), spray paints, electroplated coatings, etc., and widely used on various substrates like metal, plastic and glass. Compliant with international standards such as ISO and ASTM, the cross-cut test has grade 0 (5B) as the highest rating. It quickly warns risks like coating peeling and corrosion, helping industries like automotive, electronics and building materials control quality strictly. With low cost and high efficiency, it’s commonly used in R&D, quality inspection and delivery acceptance. Not applicable to thick adhesive layers and extremely soft substrates, it requires standardized operation to reduce errors, ensuring material durability.
