Volkswagen Golf Service & Repair Manual: Aquaplus system, uni (solid-colour) and metallic colours
| Uni (solid-colour) waterborne mixing paint -LWM 075 ...- |
| Metallic waterborne mixing paint -LWM 076 ...- |
| Uni (solid-colour) waterborne base coat -LUW/LWG 038 ...- |
| Metallic waterborne base coat -LMW/LWG 039 ...- |
| The Aquaplus system is a high-grade waterborne base coat
system. It is based on a special PU dispersion technology for
high-grade two-stage solid and metallic colours. |
| Recoatable with 2-pack HS clear coat |
Note
| After overspraying with 2-pack HS clear coat, it produces a
high-gloss, weather-resistant finish. |
| Surfaces coated with primer or surfacer (2-pack HS surfacer) |
| Substrates isolated with 1-pack wash primer -LVM 044 007
A2-/-LVM 044 171 A2- |
| For plastic surfaces, substrates isolated with 2-pack primer
surfacer for plastics -LKF 696 009 A2-/-LKF 696 040 A2- |
| See special notes
→ Anchor |
|
|
|
| – |
Thoroughly clean factory paint, old paint or 2-pack HS
surfacer 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. |
| – |
Wipe off any excess silicone remover with a lint-free cloth,
leaving no streaks. |
| Areas sanded to bare metal must be isolated with 1-pack wash
primer -LVM 044 007 A2-/-LVM 044 171 A2-. Bare metal spots must
not be larger than 5.0 cm in diameter. |
| If 2-pack HS surfacer is used, bare metal spots must be
isolated with 2-pack wash primer -LHV 043 000 A2- or 1-pack wash
primer -LVM 044 007 A2-/-LVM 044 171 A2-. |
| Plastic containers or tinplate containers with inner coating |
| Waterborne base coats are to be filtered through waterproof
125 μm quick sieves before application by means of cup systems. |
| Aquaplus demineralised water -LVW 010 000 A5- (according to
ISO 3696) |
| Use Aquaplus measuring stick. |
| At higher temperatures (>+25°) and high relative humidity
(>60%), adding 0-5% demineralised water -LVW 010 000 A5- is
sufficient. |
Note
| For reasons of safety, mixtures which include both micro
silver extra -LWM 076 817 A2/A4- and translucent oxide -LWM 075
831 A1- may not be stored. Risk of pressure increase in the
closed tin. |
| Any unused material is immediately to be disposed of
properly.

|
|
| Method of application: “spray”. |
|
|
|
| – |
The application viscosity at +20 °C is the “compliant” and
“HVLP” mixing viscosity. |
|
|
|
| – |
Add 10% thinner at +20 °C material temperature. |
|
|
|
| – |
Adjust spray nozzle following manufacturer's instructions to
1.2-1.3 mm for “compliancy”. |
| – |
Adjust spray nozzle following manufacturer's instructions to
1.3 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 spray operation includes a tack coat followed by a full
coat. A “finish coat” is recommended for special-effect colours. |
Note
| If the paint hue does not hide well, it may be necessary to
apply additional spray coats after an appropriate flash-off
time. |
|
|
|
| The flash-off time for clear coat application is 20 minutes
at +20 °C. |
| Ways to reduce flash-off times for small areas: |
| Surface matting can be accelerated by blowing on it with an
air diffuser (hand-held or stationary device). |
| It is also possible to blow on it with the spray gun after
waiting at least 5 minutes. |
| Ways to reduce flash-off times for large areas: |
| Surface matting can be accelerated by using stationary air
diffusing units (e.g. ceiling system), infrared drying or low
baking. |
| Ceiling system: 10-15 minutes |
| Infrared drying: 3-5 minutes |
| Cooling time at least 5 minutes |
|
|
|
| Combination booth: at least 10 minutes including heat-up
time |
| Low-bake oven: at least 5 minutes |
| Cooling time at least 5 minutes |
Note
| The specified flash-off and drying times depend on the
temperature, humidity, air drop speed in the spray booth and the
number of coats applied. The surface must, however, first appear
completely matt. |

| Blending system (for achieving a perfect colour transition
from repair to adjacent areas) |
| – |
Sand surfaced areas (dry with P400 to P500-grade paper or
wet with P800 to P1000-grade waterproof paper). |
| – |
Thoroughly but lightly sand the adjacent areas to which no
surfacer was applied with a fine emery pad. |
| – |
Thoroughly clean the whole surface with silicone remover
-LVM 020 000 A5- to remove any dust, paint residue from sanding
or any other impurities. |
| – |
Wipe off any excess silicone remover with a lint-free cloth,
leaving no streaks. |
| – |
Allow the moisture on substrates which have been wet-sanded
or cleaned to evaporate completely. |
| Blending system for metallic and solid colours: |
| – |
Spray the area on which the surfacer was applied with mixed
waterborne base coat at spray viscosity so that it forms an
opaque film. |
| – |
Extend the area of application of each subsequent coat
through a process of overlapping so that only a fade-out area
remains. |
| – |
Extend this fade out area and blend in, spraying with
reduced pressure. |
| – |
After an appropriate final flash-off time, 2-pack HS clear
coat can be applied. |
| Spraying equipment must be suitable for applying water-based
products; manufacturers' instructions must be followed. |
| The mixing colours in this top coat series can be used only
as part of a colour formula. If any mixing colour is applied
alone, the results may differ substantially from the description
in this technical data sheet. |
| Rinse with Aquaplus demineralised water -LVW 010 000 A5-
before and after use. Then wash out with nitrocellulose thinner
-LVE 856 000 A3-. |
| Collect liquid water-based waste separately from
conventional liquid waste. If the two are mixed, it may be
impossible to dispose of the mixture, or at best difficult, and
therefore expensive. |
|
|
|
| Personal protective equipment: |
| Adhere to the safety data sheet. |
| Wear personal protective equipment during application. |
