Designation:

Fine texture additive -ALN 775 108-

Issued 04.2013

Product description

The fine texture additive -ALN 775 108- is designed to be added to 2-pack HS top coats. The respective top coat is then converted into a texture paint

that can be used for treating plastic vehicle parts.

Technical data sheet

Substrate

Suitable substrates:

Hardened, well-preserved and lightly sanded old or factory finish.

Plastic parts coated with primer or surfacer.

Note For plastic parts, see "The VW/Audi painting system for plastic parts" (data sheet no. 5.74).

Substrate pre-treatment:

  • Thoroughly clean with silicone remover -LVM 020 000 A5- or slow-drying silicone remover -LVM 020 100 A5-.
Texture additive
  • Dry sand using orbital sander (P400 to P500 grade) and dust collector.
Texture additive
  • Alternatively, wet sand with P800-grain sandpaper.
Texture additive
  • Before recoating, use a suitable cleaning agent to ensure a clean surface free of residues.

Application
Texture additive

Mixing ratio

Mixing ratio 1:1 by volume with 2-pack HS top coat:

  • Then mix this 4:1 by volume with a suitable 2-pack VHS hardener.

See technical data sheet for 2-pack VHS hardener → Chapter.

Thinner:

2-pack thinner, special -LVM 009 200 A2/A5-

2-pack thinner, slow-drying -LVM 009 300 A2-
Texture additive

Application time/pot life:

  • Mixed for spraying, 90 to 100 minutes at +20 °C
Texture additive

Method of application: “spray”.
Texture additive
  • Application viscosity 4 mm, +20 °C, DIN 53211
  • The application viscosity at +20 °C is the “compliant” and “HVLP” mixing viscosity.
Texture additive
  • Add 15 % thinner at +20 °C material temperature.
Texture additive
  • Adjust spray nozzle following manufacturer's instructions to 1.3-1.4 mm for “compliancy”.
  • Adjust spray nozzle following manufacturer's instructions to 1.3-1.5 mm for “HVLP”.
  • Adjust spray pressure following manufacturer's instructions to 2.0-2.5 bar for “compliancy”.
  • Adjust atomising pressure following manufacturer's instructions to 0.7 bar for “HVLP”.
Texture additive
  • Two spray passes (with intermediate flash-off time of 5 to 10 minutes) are necessary to achieve the recommended dry-film thickness of 50-60 µm.
Note

It is not necessary to add the elastic additive -ALZ 011 001-.

The fine texture additive -ALN 775 108- is only suitable for use on add-on parts (e.g. bumpers or spoilers). Various effects can be created using different spraying techniques and layer thicknesses. The fine texture additive -ALN 775 108- is thixotropic and becomes liquid when stirred well.
Texture additive
