Volkswagen Polo Service & Repair Manual: Matting Component -ALN 775 106

Definition:

Matting Component -ALN 775 106-

Edition 04/2013

Product Description

With the two-part HS top coat, the Matting Component -ALN 775 106- produce a matted top coat coating for plastic finishes.

Application Instructions

Base Surface

Suitable base surfaces:

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-.

Then, sand.

Use a suitable cleaning agent before reworking to ensure a clean and residue-free surface.

Processing

Applicable products:

Two-part HS top coat

Two-Part VHS Hardener -LHA 009 051 A2-/-LVM 009 051 A5-

Two-Part VHS Hardener, Long -LHA 009 052 A2-/-LHA 009 052 A3-

Two-Part VHS Hardener, Extra Long -LHA 009 053 A2-

See technical application information for the two-part VHS hardener. Refer to → Chapter „Two-Part VHS Hardener and Two-Part VHS Performance Hardener“.

Matting Table:

Mixing Ratio (in % by weight)		Gloss Units (GU) according to DIN 67530
Matting Component -ALN 775 106-	Two-Part HS Top Coat	60° angle
10	90	85-95 GU*
20	80	80-90 GU*
30	70	75-90 GU*
40	60	60-90 GU*
50	50	25-65 GU*
* 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.

Mixing ratio

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“.

Dilutable with:

Two-Part Thinner -LVE 009 001 A5-

Two-Part Thinner, Special -LVM 009 200 A2/A5-

Two-Part Thinner, Long -LVM 009 300 A2-

Processing time/pot life:

Ready to spray in 60 to 90 minutes at +20 °C

Application type “coat”

Processing viscosity at +20 °C material temperature

Processing viscosity “Compliant” and “HVLP”:

18-20 Seconds

Adding 15 % thinner at +20 °C 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 thickness	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%).

Drying

Air dry at +20 °C room temperature:

Dust dry after 30 to 50 minutes

Ready for assembly after 5 to 6 hours

Dry overnight

Final drying time with forced drying is a minimum of 5 to 10 minutes.

Forced dry at +60 °C 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

Personal Protective Equipment:

Note the safety data sheets

Wear the personal protective equipment during application
