However, in the case of a transparent surface, the light passes through the surface instead of being reflected from it. As a result, the scanner cannot detect the surface structure. b) Reflective parts In the case of reflective or specular surfaces, the light beam is emitted in focused rather than in diffusely reflected back. Thus, it is not possible for the scanner to capture the surface. c) Deepenings If the object being scanned has pronounced indentations, the scanner will receive a reflection from the walls of the indentation. This results in a disturbance of the light pattern, which shows up in the scan as "artifacts" or erroneous data. d) High quality and accuracy For the most accurate and high quality measurements, a scanning spray should be used to eliminate possible interfering factors such as differences in the reflectance property, texture and/or color of the object to be scanned. The use of scanning spray creates a matte, white and homogeneous coating that reduces reflections and other inhomogeneities, thus creating excellent scanning conditions.

Technical data sheet AESUB green - vanishing scanning spray Rev. 02/2022 Page 2 of 6 The matting sprays used in 3D scanning technology for the antireflection coating of surfaces can be divided into two product groups: Semi-permanent pigment spray  White, non-grip coating remains on the component after scanning  Necessary cleaning of the scan object or its disposal if cleaning is not possible Volatilizing (sublimating) scanning spray  White, non-slip coating evaporates automatically after scanning, eliminating the need for component cleaning  Laboratories, sensors, environments and users...

Material compatibility AESUB scanning sprays are optimized for their material compatibility, however material compatibility for specific applications cannot be guaranteed. The specific material compatibility must therefore be checked by the user before application. AESUB green contains solvents. For wax-like surfaces or simple, 1K coatings, please test thoroughly beforehand. Details can be found in the Safety Data Sheet (SDS) (https://aesub.com/download). 4. Layer thickness AESUB green has been optimized...

Technical data sheet AESUB green - vanishing scanning spray Rev. 02/2022 Page 4 of 6 SPRAY Apply AESUB green from a distance of 15-20 cm with a spray gun. We recommend either the battery-operated AESUB spray gun (AESSG001) or spray guns with a nozzle diameter of 1 mm or more. Spray the complete surface to be scanned. Spray evenly, with the nozzle pointed at the object, slowly back and forth to obtain an even coating. AESUB green is applied "wet in wet" in a crosscoat process. The solvent evaporates within a few seconds, while the active ingredient remains on the surface as a coating. The...

Evaporation / Sublimation The sublimation of AESUB green takes about 6h, but this depends largely on the following factors: a) Temperature  high ambient temperatures shorten the sublimation time  low ambient temperatures extend the sublimation time b) Air flow  Air currents (wind, ventilation) shorten the sublimation time c) Surface  Uneven structures of the surface lengthen, even structures shorten the sublimation time  In exposed areas (outer corners), the sublimation time is shortened d) Material...

Technical data sheet AESUB green - vanishing scanning spray Rev. 02/2022 Page 6 of 6 Scanning large objects Since AESUB green can remain on the component for a very long time depending on the layer thickness, you can digitize as usual in most cases. The only recommended change in the usual way of working is that you apply the measuring points (targets) to the surface after spraying on AESUB green. This eliminates the need to clean the points before scanning. 8. More information a) Storage  Optimal storage temperature between 18°C and 21°C (64.4°F and 69.8°F)  Minimum shelf life: 5 years ...
