Volkswagen Golf Service & Repair Manual: Matting additive -LVM 769 810 A2
Matting additive -LVM 769 810 A2- |
The matting additive -LVM 769 810 A2- is an additive for
2-pack HS clear coats and 2-pack HS top coats which produces a
matt effect on painted metallic or plastic substrates. |
The product is typically used when larger areas need to be
painted as well as for full-vehicle paint jobs, but also for
painting small and add-on parts. |
Hardened, well-preserved and lightly sanded old or factory
finish. |
Plastic or metal parts coated with primer or surfacer. |
Note
For plastic parts, see "The VW/Audi painting system for
plastic parts" (data sheet no. 5.74). |

Adjusting the degree of gloss/matting; Application
instructions |
Note
Refer to "Gloss level adjustment for 2-pack HS clear coats"
(data sheet no. 5.75) and "Paintwork repair system for vehicles
with a matt finish" (data sheet no. 5.76). |
Note
It is not necessary to add the elastic additive -ALZ 011
001-. |
Shake or stir the matting additive -LVM 769 810 A2- well in
the can. |
Mix the matting additive -LVM 769 810 A2- with 2-pack HS
clear coat or 2-pack HS top coat according to the respective
specifications. Add the hardener and the reducer right before
application. 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 the matting additive might influence the coverage. |
It is absolutely necessary to test the mixture on a spray
sample prior to application in order to achieve the degree of
gloss that matches the vehicle. Measuring the degree of gloss
(at an angle of 60°) on adjacent parts may also be helpful. |
Blending in or refinishing the matt clear coat within a
component, e.g. a side panel, or Clever Repair is not possible. |
It is not possible to polish dust inclusions, therefore
cleanliness during the entire refinishing process is very
important. |
The actual gloss level achieved is influenced by a number of
factors apart from differences relating to the colour shade. The
following chart shows some additional parameters and their
effects on the degree of gloss. |
|
|
|
Higher gloss |
Low gloss |
Faster-drying hardeners |
Slower-drying hardeners |
Faster-drying thinners |
Slower-drying thinners |
Higher application
viscosity |
Lower application viscosity |
Higher dry layer
thickness |
Lower dry layer thickness |
Shorter flash-off time |
Longer flash-off time |
Forced drying |
Air drying |
Factors influencing the degree of gloss: |
The actual gloss level produced depends on the
hardener/thinner used, the application and the drying method as
well as on the film thickness. Depending on the respective
parameter, the gloss level may vary by up to 20 %. |
|
|
|
Final flash-off time with force drying is at least
15-20 minutes. |
|
|
|
Force drying period at material temperature of +60-65 °C is
45 minutes. |
