Technical data sheet AESUB orange - vanishing scanning spray Rev. 02/2022 Page 1 of 6 AESUB orange - long-lasting Vanishing Scanning Spray (sublimating) Does not contain any pigments and no TiO2 - the spray fog does not damage sensitive measurement equipment Time and cost savings - no need for subsequent cleaning; the spray sublimates and evaporates after the scanning process Thin, homogeneous and non-slip coating Reference points adhere to the coating Excellent scannability Developed and approved by scan experts General information Even when using state-of-the-art scanners, in many applications it is necessary to use matting agents to achieve good contrast values and thus precise measurement results: a) Transparent parts Optical metrology relies on light emitted from the scanner reflecting off the surface of the part being scanned back into the scanner's sensor. 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 orange - 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...

Technical data sheet AESUB orange - vanishing scanning spray Rev. 02/2022 Page 3 of 6 3. 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 orange contains solvents. For details, please refer to the Safety Data Sheet (SDS) (https://aesub.com/download). 4. Range With one can of AESUB orange you can cover approx. 4-6m² area 5. Layer thickness AESUB orange has been optimized for...

Technical data sheet AESUB orange - vanishing scanning spray Rev. 02/2022 Page 4 of 6 SPRAY Apply AESUB orange from a distance of 15-20 cm. Spray the complete surface to be scanned. Operate the spray head and slowly move the spray can back and forth evenly, with the nozzle pointed at the object, to obtain an even coating. Avoid "wagging" the can. AESUB orange is applied "wet". The solvent volatilizes within a few seconds, while the active ingredient remains on the surface as a coating. The degree of whiteness of the coating increases with progressive evaporation of the solvent. Complete evaporation...

Evaporation / Sublimation However, the sublimation of AESUB orange takes between 12h and 24h 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)...

Technical data sheet AESUB orange - vanishing scanning spray Rev. 02/2022 Page 6 of 6 Scanning large objects Since AESUB orange remains on the component for a very long time, 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 orange. This eliminates the need to clean the points before scanning. • Spray the first section with AESUB orange and apply the adhesive reference points for this section onto the spray layer 8.
