Gloss Level Adjustment/Matting
System information. Refer to → Chapter „Repair Paint System for Matte Painted Vehicles“.
Technical application information. Refer to → Chapter „Matting Component -LVM 769 810 A2-“.
Apart from color-dependent differences, the actual gloss level is influenced by different factors.
The addition of other hardeners not mentioned in these instructions is generally possible, but can result in different application types, drying conditions and layer thicknesses which leads to different gloss levels (up to 20%).
   
Higher Gloss Level Lower Gloss Level
Shorter Hardener Longer Hardener
Shorter Thinner Longer 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
 
  Note
It is absolutely necessary to test on sheet metal in order to achieve the appropriate gloss level for the vehicle. Gloss level measurements (60° angle) at the adjacent parts can also be helpful.

–  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.
 

Gloss Level Adjustment of HS Clear Lacquer and HS Top Coat

–  Apply in two spray applications with a 5 to 10 minute intermediate ventilation time. The first spray application is applied lightly, but completely. (Follow the processing instructions).
The recommended dry layer thickness is between 60 and 80 µm.
Application Instructions
To achieve the best possible and homogenous mat effect pay attention to the following notes for the application:
  Note
The spraying distance to the object is larger than the standard application, to use the full the atomization of the spray pattern. (To prevent streaking)
Pay attention that there is even overlap of the “spray passes” and that enough wet spray film is applied. There is a risk or cloudiness from too dry of application due to uneven drying or due to unabsorbed spray mist.
For less opaque colors, it may be necessary to apply another spray application after the corresponding ventilation time.
A touch-up/repair of the matted clear coat within the surface (for example, side part or clever repair) is not possible.
Drying
 

Gloss Level Adjustment of HS Clear Lacquer and HS Top Coat

–  Final drying time with forced drying is 15 to 20 minutes.
 

Gloss Level Adjustment of HS Clear Lacquer and HS Top Coat

–  Forced drying at +60 to 65 °C (140° to 149°F)object temperature is 45 minutes.
  Note
The addition of Two-Part Elastic Additive -ALZ 011 001- is omitted.
Stir or shake the Matting Component -LVM 769 810 A2- in the can well. Mix with HS clear coat and HS top coat according to specification and infuse with hardener and thinner just before processing.
The processing of the ready-to spray mixture should immediately follow. If the mixture remains in the mixing- or spray gun receptacle for a longer period of time (15 minutes), it should be stirred again before continuing to use (separation).
The application of the Matting Component -LVM 769 810 A2- can influence the covering capacity.
Dust inclusions cannot be polish out, so therefore ensure that absolute cleanliness is maintained during the entire painting process.
