* 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-

–  Processing viscosity at +20 °C (68 °F) material temperature
Processing viscosity “Compliant” and “HVLP”:
18-20 Seconds
 

Matting Component -ALN 775 106

–  Adding 15 % thinner at +20 °C (68 °F) material temperature
 

Matting Component -ALN 775 106

–  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.
 

Matting Component -ALN 775 106

–  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.
 

Matting Component -ALN 775 106

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 (68 °F) room temperature:
Dust dry after 30 to 50 minutes
Ready for assembly after 5 to 6 hours
Dry overnight
 

Matting Component -ALN 775 106

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

Matting Component -ALN 775 106

Forced dry at +60 °C (140 °F) object temperature for 30 to 40 minutes
 

Matting Component -ALN 775 106

Final drying time for IR drying is a minimum of 5 to 10 minutes.
 

Matting Component -ALN 775 106
