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 on the substrate, and a top layer of hard paint that blocks ultraviolet rays. When cracks occur in the substrate, the primer layer stretches while the top layer cracks, exposing the primer layer. Ultraviolet rays are then directed at the exposed primer layer, causing the fluorescent pigments to emit light for inspection. This catalog includes photos of visual inspections of bolt and nut loosening conducted using the Cladis Method, as well as painting and construction processes. 【Features of Cladis Method Paint (Common)】 ■ Inspection possible from a distance, reducing inspection time ■ Inspection possible in dark areas ■ Anyone can conduct inspections ■ Safe as it is solvent-free and water-based ■ Inspections from the ground improve safety *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 the structure in advance, cracks will emit light under special ultraviolet rays, making inspection work 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 coating consists of two layers, and by irradiating ultraviolet light during inspections, only the cracked areas will emit light. 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 oversights during inspections ○ Increased inspection speed For more details, please contact us or download the catalog.
