Volkswagen Golf Service & Repair Manual: Setting the gloss level of HS clear coats and HS top coats
The gloss level of HS clear coats and HS top coats is set by
mixing them with matting additive -LVM 769 810 A2- for plastic
and metal substrates. |
The information on the factors that influence gloss level
contained in these instructions is intended to assist the
technician in obtaining the desired gloss level, even under
varying working conditions. |

Refer to system information
→ Chapter „Repair paintwork system for matt-finished vehicles“. |
Refer to technical data sheet
→ Chapter „Matting additive -LVM 769 810 A2-“. |
The actual gloss level achieved is influenced by a number of
factors apart from differences relating to the colour shade. |
While other hardeners or thinners not described in this data
sheet may also be used, they may result in different gloss
levels (up to 20%) in the same way as different application
types, drying conditions and layer thicknesses do. |

|
Higher gloss |
Low gloss |
Faster-drying hardener |
Slow-drying hardener |
Faster-drying thinners |
Slower-drying thinners |

Note
It is absolutely necessary to use spray samples prior to
application in order to achieve the gloss level that matches the
vehicle. Measuring the gloss level (at an angle of 60°) on
adjacent components may also be helpful. |

Method of application: “spray”. |
– |
Application viscosity 4 mm, +20 °C, DIN 53211 |
Application viscosity 4 mm, gravity-feed spray gun
“Compliant” and “HVLP” |
|
|
|
– |
Addition of thinner at material temperature of +20°C:
depending on product used |
|
|
|
– |
Adjust spray nozzle following manufacturer's instructions to
1.3-1.4 mm for “compliancy”. |
– |
Adjust spray nozzle following manufacturer's instructions to
1.3-1.4 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”. |
|
|
|
– |
Apply in 2 spray passes with a flash-off time of 5 to
10 minutes between the passes. The first coat is applied with
restraint, but still uniformly (observe application
instructions). |
The specified thickness for the dry film is 60-80 µm. |
To achieve the best possible and homogeneous matting effect,
the following points should be adhered to during application: |
Note
-
|
The spraying distance to the object is somewhat
greater than the standard application in order to use the
spray atomisation to its fullest effect. (Prevents
streaking) |
-
|
It must be ensured that “spray passes” featheredge
evenly and an adequately wet spray film is applied.
Application in excessively dry conditions poses the risk of
clouding due to uneven flash-off or due to the spray mist
not being absorbed. |
-
|
For paint with poor covering properties, it may be
necessary to apply another spray pass after a suitable
flash-off time. |
-
|
Blending in or refinishing the matt clear coat within
a component, e.g. a side panel, or speed repair is not
possible. |
|
|
|
– |
Final flash-off time with force drying is 15 to 20 minutes. |
|
|
|
– |
Force drying at +60°C to +65°C material temperature in
45 minutes. |
Note
-
|
It is not necessary to add 2-pack elastic additive
-ALZ 011 001-. |
-
|
Stir or mix matting additive -LVM 769 810 A2- well in
the can. Then, mix it with HS clear coat or HS top coat as
specified and do not add hardener and thinner until just
prior to use. |
-
|
The ready-to-spray mixture should be applied
immediately. If the mixture is left to stand in the mixing
cup or spray gun cup for a longer period of time (15 min.),
it must be stirred again prior to further application
(sedimentation behaviour). |
-
|
Adding matting additive -LVM 769 810 A2- might
influence the coverage. |
-
|
It is not possible to polish dust inclusions,
therefore cleanliness during the entire refinishing process
is very important. |
|
|
|
Personal protective equipment: |
|
Adhere to the safety data sheet. |
|
Wear personal protective equipment during application. |
