Volkswagen Polo Service & Repair Manual: Matting Component -ALN 775 106
| Matting Component -ALN 775 106- |
| With the two-part HS top coat, the Matting Component -ALN
775 106- produce a matted top coat coating for plastic finishes. |
| Hardened, well-preserved and sanded old paint or factory
paints |
| Plastic parts treated with primer or filler |
 Note
| For information about plastic parts, refer to "The VW/Audi
Coating System for Plastic Parts" (Data Sheet 5.74). |
|
|
|
| Pre-treatment of base surfaces: |
| – |
Carefully clean using Silicone Remover -LVM 020 000 A5- or
Silicone Remover, Long -LVM 020 100 A5-. |
|
|
|
| – |
Use a suitable cleaning agent before reworking to ensure a
clean and residue-free surface. |

Depending on color; bright colors usually tend to lose more gloss than
darker colors when adding Matting Component -ALN 775 106-. Other factors
influence the gloss level. Refer to the gloss level influencing factors
table. |
| Combining the Matting Mixture: |
| Mixing ratio 4:1 by volume with: |
| Two-Part VHS Hardener -LHA 009 051 A2-/-LVM 009 051 A5- (for
small to medium-sized surfaces, at moderate temperatures) |
| Two-Part VHS Hardener, Long -LHA 009 052 A2-/-LHA 009 052
A3- (for larger surfaces at moderate temperatures) |
| Two-Part VHS Hardener, Extra Long -LHA 009 053 A2- (for
large surfaces and high temperatures) |
| See technical application information for the two-part VHS
hardener. Refer to
→ Chapter „Two-Part VHS Hardener and Two-Part VHS Performance
Hardener“. |

| Processing time/pot life: |
| – |
Ready to spray in 60 to 90 minutes at +20 °C (68 °F) |
|

Processing viscosity at +20 °C (68 °F) material temperature |
| Processing viscosity “Compliant” and “HVLP”: |

|
| – |
Adding 15 % thinner at +20 °C (68 °F) material temperature |
|
|
|
| – |
Set spray nozzle (see manufacturer's information):
“Compliant” 1.3 to 1.4 mm. |
| – |
Set spray nozzle (see manufacturer's information): “HVLP”
1.3 to 1.4 mm. |
| – |
Set spray pressure (see manufacturer's information):
“Compliant” to 2.0 to 2.5 bar. |
| – |
Set atomizing pressure (see manufacturer's information):
“HVLP” 0.7 bar. |
|
|
|

Two spray applications are required with drying time to get
a dry layer thickness of between 50 and 60 µm. |
Note
| The addition of Elastic Additive -ALZ 011 001- is omitted. |
| The Matting Component -ALN 775 106- is not suitable for
matting clear coats. |
| Matting Component -ALN 775 106- is thixotropically mixed,
which means it becomes fluid when strongly stirred. If
necessary, it is recommended to use an agitator or manually
shake the can. It should also be mixed in the mixer 15 minutes
before using. |
| Adding the matting compound can influence the covering
capacity. |
| Apart from color-dependent differences, the actual gloss
level is influenced by different factors. In the following
comparison, various additional parameters and their effect on
the gloss levels are represented. |
|
|
|
| Higher Gloss Level |
Lower Gloss Level |
| longer hardener |
shorter hardener |
| longer thinner |
shorter thinner |
| higher processing
viscosity |
lower processing viscosity |
| higher dry layer

lower dry layer thickness |
| shorter ventilation time |
longer ventilation time |
| forced drying |
Air drying |
| Influencing Factors on the Gloss Level: |
| Using different hardeners, thinners, application types,
drying conditions and layer thicknesses lead to different gloss
levels (up to 20%). |
|
|
|
| Air dry at +20 °C (68 °F) room temperature: |
| Dust dry after 30 to 50 minutes |
| Ready for assembly after 5 to 6 hours |
|
|
|
| Final drying time with forced drying is a minimum of 5 to 10
minutes. |
|
|
|
| Forced dry at +60 °C (140 °F) object temperature for 30 to
40 minutes |
|
|
|
| Final drying time for IR drying is a minimum of 5 to 10
minutes. |
|
|
|
| IR dry with short-wave radiator for 5 minutes at 50 % power
and for 10 minutes at 100 % power |
|
