| The 2-pack HS top coat series is a high-solid, uni
(solid-colour) top-coat system. It is used for car finishing. |
| The colour range is comprehensive due to a selection of
mixture paints adjusted for this purpose. |
| VOC conformity under 420 g/l |
| Fully cured, solvent-resistant, well-preserved and lightly
sanded old paint or original paint |
| Surfaces treated with primer or surfacer |
| Suitable priming materials: |
| Depends on the object and the substrate, in accordance with
recommendations for paintwork structure |
|
|
|
| – |
Thoroughly clean with silicone remover -LVM 020 000 A5- or
slow-drying silicone remover -LVM 020 100 A5-. |
|
|
|
| – |
Dry sand using orbital sander with P400 to P500-grain
sandpaper and dust collector. |
|
|
|
| – |
Or lightly “wet” sand using P800 to P1000-grain sandpaper. |
|
|
|
| – |
Before recoating, use a suitable cleaning agent to ensure a
clean surface free of residues. |
|
|
|
| 2-pack VHS hardener, fast-drying -LHA 009 050 A2- (for small
areas and spot repair) |
| 2-pack VHS hardener -LHA 009 051 A2-/-LVM 009 051 A5- (for
small to medium-size areas at moderate temperatures) |
| 2-pack VHS hardener, slow-drying -LHA 009 052 A2-/-LHA 009
052 A3- (for larger areas at moderate temperatures) |
| 2-pack VHS hardener, extra slow-drying -LHA 009 053 A2- (for
large areas at high temperatures) |
| See technical data sheet for 2-pack VHS hardener
→ Chapter |
Note
| The mixture ratio for black matt -L2K 073 3FZ A2- and grey
matt -L2K 073 7DL A2- is 4:1 with2-pack VHS hardener -LHA 009
051 A2-/-LVM 009 051 A5-. |
|
|
|
| Application time/pot life: |
| – |
Mixed for spraying, 60 to 90 minutes at +20°C |
| May be thinned with 2-pack thinner, special -LVM 009 200
A2-, HS spot thinner -LVM 006 000 A2- or 2-pack thinner,
slow-drying -LVM 009 300 A2- |
Note
| If HS spot thinner -LVM 006 000 A2- is used, observe the
technical data sheet
→ Chapter. |
|
|
|
| Method of application: “spray”. |
|
|
|
| – |
Application viscosity for +20 °C material temperature. |
| Application viscosity “compliant” and “HVLP”: |
| 18-25 seconds for black matt -L2K 073 3FZ A2- and grey matt
-L2K 073 7DL A2-. |
|
|
|
| – |
Add 12.5% thinner at +20 °C material temperature. |
|
|
|
| – |
Adjust spray nozzle following manufacturer's instructions to
1.2-1.4 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”. |
|
|
|
| – |
One-and-a-half spray coats are necessary to achieve the
recommended dry-film thickness of 50-60 µm. |
Note
| When used for spot repairs (Clever Repair method), 12.5% HS
spot thinner -LVM 006 000 A2- may be substituted for the 12.5%
2-pack thinner, special -LVM 009 200 A2-. |
| Do not apply to horizontal surfaces. |
| The first half-coat should form a uniformly thin film over
which a full spray coat is directly sprayed. |
| If the paint hue does not hide well, it may be necessary to
apply an additional spray coat after an appropriate flash-off
time. 2-pack HS top coat can be recoated with more of the same
paint within 24 hours without »intermediate
sanding«. |
| The mixing colours in this mixing paint series can be used
only as part of a colour formula. If any mixing colour is
applied alone, the results may differ substantially to the
description in this technical data sheet. |
|
|
|
| Air drying at +20 °C ambient temperature: |
| Dust dry in 20-30 minutes |
| Dry for assembly in 5-6 hours |
|
|
|
| Final flash-off time with force drying is at least
5-10 minutes. |
|
|
|
| Force drying at +60 °C material temperature in
15-20 minutes. |
|
|
|
| The final flash-off time with infrared drying is at least
5 minutes. |
|
|
|
| Infrared drying of light colours with short-wave radiant
heater: 5 minutes at 50% power and then 10 minutes at 100%
power. |
| Infrared drying of light colours with medium-wave radiant
heater: 15 minutes |
| Infrared drying of dark colours with medium-wave radiant
heater: 12 minutes |
| Infrared drying of dark colours with short-wave radiant
heater: 12 minutes at 50% power |
Note
| If a short-wave radiant dryer is operated at 100% power to
dry dark colours, bubbles or blisters may develop when the next
coat is applied. |
|
|
|
| First mix the base material with 15% elastic additive -ALZ
011 001-. |
| Mixture with 2-pack VHS hardeners, 3:1 with 15% thinner |
|
|
|
| First mix the base material with 100 % matting additive -ALN
775 106- or fine texture additive -ALN 775 108-. |
Note
| No further addition of matting additive -ALN 775 106- is
necessary for the 2-pack uni (solid-colour) top coats black matt
-L2K 073 3FZ A2- and grey matt -L2K 073 7DL A2- because they are
already prepared for a matt finish. |
| Mixing ratio with 2-pack VHS hardeners -LHA 009 051 A2-/-LVM
009 051 A5- is 4:1 with 15% thinner. |
| Two spray coats with 5-10 minutes flash-off time are
necessary for a uniform paint film surface. |
