Pranas Chemical Co., Ltd. has developed a new environmentally friendly water-based paint for crack detection painting methods (Cladis method). It can be applied not only to concrete but also to steel bridges, and it allows for spray application, enabling large areas to be covered at once. Furthermore, it is a highly sensitive paint that can also detect loosening of screws. This document introduces the "development history of the Cladis method," as well as the "principle of crack detection" and "the application of technology for 'screw loosening detection' and its principle explanation." Please download the PDF document to learn more.

The "Cladis Method" involves forming a primer layer of elastic paint containing fluorescent pigments and a top layer of hard paint that blocks ultraviolet rays on a substrate. When cracks appear in the substrate, the primer layer stretches while the top layer cracks, exposing the primer layer, which is then irradiated with ultraviolet light to make the fluorescent pigments in the primer layer emit light for inspection. This catalog includes photos of visual inspections of bolt and nut looseness conducted using the Cladis Method, as well as details on the painting and construction processes. 【Features of Cladis Method Paint (Common)】 ■ Inspection possible from a distance, reducing inspection time ■ Inspection possible in dark places ■ Anyone can perform the inspection ■ Safe as it is solvent-free and water-based ■ Inspections from the ground improve safety during inspections *For more details, please refer to the catalog or feel free to contact us.

The Cladis method is a painting system that detects "cracks" that occur on concrete surfaces. By applying this paint to structures in advance, cracks will emit light under special ultraviolet rays, making inspection tasks very simple, accurate, and cost-effective. The frequency of inspections can also be increased, allowing for precise understanding of structural changes. Emergency inspections immediately after disasters such as earthquakes or floods can be conducted swiftly. The two-layer coating emits light only at the cracked areas when exposed to ultraviolet light during inspections. The painting does not require special techniques or tools, making the inspection process straightforward and reducing work time. 【Features】 ○ Easy to apply ○ Glows under ultraviolet light ○ Easy crack detection ○ No oversight during inspections ○ Increased inspection speed For more details, please contact us or download the catalog.
