Reflecon Tarnish 50

The Tarnish 50 3D scanning spray from Reflecon is sublimating spray based on optimized cyclododecane, with reduced solvent content and a pleasant odor. The Tarnish 50 spray helps enhance the 3D laser scanning process by acting as a matting agent on challenging surfaces such as reflecting, mirroring, transparent, or dark areas. This spray is suitable for use in various industries, including automotive, aerospace, engineering, medical, art and culture, and more, for applications such as R&D, metrology, quality control, and reverse engineering.

Thanks to its long sublimation time (5-8 hours), the Tarnish 50 scanning spray is ideal for the scanning of large objects. The Tarnish 50 spray can be used with a wide range of materials, including ferrous materials like cast uncoated steel, non-coated non-ferrous materials such as wood, glass, and ceramics, objects coated with 2-component lacquer, and numerous plastics such as PE, PP, PET, PA, hard PVC, PS, ABS, PMMA and PC. It is recommended to test the spray's suitability on an invisible spot before full application to avoid potential damage to the object being scanned.

Key features of Tarnish 50 include a residue-free application, and no dust generation during spraying. These qualities keep the workspace clean and protect 3D scanning equipment while preventing contamination in sensitive environments such as laboratories. The spray forms a thin and uniform layer that provides excellent adhesion and allows for easy removal of marker points.

The sublimation time of Tarnish 50 ranges from 5-8 hours, depending on factors such as the material, surface texture, and ambient temperature. Higher temperatures, especially above 30°C, shorten the sublimation time, while lower temperatures extend it. Rough surfaces can prolong sublimation time, whereas smooth surfaces accelerate the process. Applying a thicker layer can also increase sublimation time. The recommended layer thickness for optimal results is 5-35 μm.
