Volkswagen Golf Service & Repair Manual: Aquaplus system (pearlescent and heliochrome)

Designation:
Pearlescent waterborne base coat -LPW 040 ...-
Heliochrome waterborne base coat -LHW 046 ...-
Pearlescent waterborne mixing paint -LWM 076 ...-
Issued 11.2012
Product description
The Aquaplus system is a high-grade waterborne base coat system based on special PU dispersions.
The base coat can be used for two-stage pearlescent or heliochrome finishes on passenger cars and commercial vehicles.
Properties:
Easy to apply
Good vertical stability
Good hiding power
Recoatable with 2-pack HS clear coat
VOC compliant
  Note
After overspraying with 2-pack HS clear coat, it produces a high-gloss, weather-resistant finish.
Technical data sheet
Substrate
Suitable substrates:
Intact old paint
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
   
Substrate pre-treatment:
–  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-.
 

Aquaplus system (pearlescent and heliochrome)

–  Dry sand using orbital sander with P400 to P500-grain sandpaper and dust collector.
 

Aquaplus system (pearlescent and heliochrome)

–  Or lightly “wet” sand using P800 to P1000-grain sandpaper.
 

Aquaplus system (pearlescent and heliochrome)

–  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.
Special notes
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-.
Application
Mixing containers:
Plastic containers or tinplate containers with inner coating
Sieves:
Waterborne base coats are to be filtered through waterproof 125 μm quick sieves before application by means of cup systems
Thinner:
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.
Preparation:
A special base coat (application of solid-colour waterborne base coat) is necessary for three-stage pearlescent colours. The respective hue must be determined from the formula information systems.
Pearlescent waterborne base coat is applied for pearlescent finishes.
 

Aquaplus system (pearlescent and heliochrome)

Method of application: “spray”.
 

Aquaplus system (pearlescent and heliochrome)

–  The application viscosity at +20 °C is the “compliant” and “HVLP” mixing viscosity.
 

Aquaplus system (pearlescent and heliochrome)

–  Add 10% thinner at +20 °C material temperature.
 

Aquaplus system (pearlescent and heliochrome)

–  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”.
 

Aquaplus system (pearlescent and heliochrome)

–  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 total film thickness (including the solid-colour waterborne base coat) must not exceed 45 µm.

Drying
 

Aquaplus system (pearlescent and heliochrome)

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
 

Aquaplus system (pearlescent and heliochrome)

Low baking at +60 °C
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.

Recoating
Recoat with:
2-pack HS clear coat from the Volkswagen Genuine paint programme
Special notes
  Note
The decision to use two or three coats (with a special undercoat) depends on the factory finish.
The respective undercoat colour is stated in the formula information systems.
Blending system (for achieving a perfect colour transition from repair to adjacent areas)
Preparation:
–  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.
Two-stage pearlescent and heliochrome colours:
–  Spray the area on which the surfacer was applied with mixed pearlescent or heliochrome 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.
Three-stage pearlescent colours:
–  Blend in the area on which the surfacer was applied with the mixed solid-colour waterborne base coat (see base coat colour application) using reduced pressure.
–  Spray the same area with the mixed pearlescent waterborne base coat, overlapping slightly and at reduced pressure to match the original finish.
–  Blow dry with the spray gun after each coat.
Product application
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.
Cleaning of tools
Rinse with Aquaplus demineralised water -LVW 010 000 A5- before and after use. Then wash out with nitrocellulose thinner -LVE 856 000 A3-.
Waste disposal
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.
