Permanent Mattifying Spray for 3D Scanning

Without TiO2

SPRAY | SCAN | DONE

Even with state-of-the-art scanners, it is necessary to apply the matting spray in several application cases:

a) Transparent parts

Since we are dealing with optical technologies, the light must be reflected from the surface into the scanner's sensor. In the case of a transparent surface, however, the light will pass through the surface instead of being reflected by it. As a result, the scanner is unable to capture the surface structure.

b) Reflective parts

In case of reflective parts, such as a mirror, the light beams will be reflected in a focused way instead of diffused. This means that the chance of a beam hitting the scanner reflector is greatly reduced and the scanner will only capture a fraction of the reflected light beams.

c) Deep cavities

When the object to be scanned has deep cavities, the scanner receives a reflection from the cavity walls at the bottom. This causes disturbances in the light pattern that manifest themselves in the scan as "artifacts" or incorrect data.

d) High quality and precision

When quality and accuracy are important, you could apply the spray to remove color differences, reflection differences, texture, etc. as much as possible.

Using the spray creates a matt white coating that reduces reflections and other inhomogeneities and thus provides a perfect scanning condition.

In general, matting sprays used in 3D metrology for anti-reflective coating can be classified into the following two product groups:

Permanent sprays

• the surface remains white after scanning
• required cleaning or disposal of the scanned object

Vanishing sprays

• the coating evaporates automatically
• no cleanup required after scanning
• no contamination from pigments of laboratories, sensors, environments, scanners and users

AESUB white - strengths

AESUB white is a permanent scanning spray, developed by scanning experts.

It is the result of further development of permanent scanning sprays.

The spray applies a matte, homogeneous layer to the object surface. It was developed for optimal contrast values in optical scanning applications. AESUB white contains pigments, propellant and solvent and has been optimized for material compatibility. AESUB white sets new standards by optimizing surface homogeneity and reducing layer thickness.

Unlike traditional sprays, AESUB white is free of titanium dioxide, which has been linked to carcinogenic inhalation incidents by the European Chemicals Agency.

The features of AESUB white are:

• optimal contrast values
• average layer thickness of ~7 μm
• consistent and homogeneous coating
• Optimized material compatibility
• free of titanium dioxide (TiO2)
• excellent scannability
