Volkswagen Tiguan Service and Repair Manual: Aquaplus System (Pearl Effect and Heliochrome)

Definition:

• Water-Based Pearl Effect Base Paint -LPW 040 ...-
• Water-Based Heliochrome Base Paint -LHW 046 ...-
• Water-Based Pearl Effect Mixed Paint -LWM 076 ...-

Product Description

The Aquaplus System is a high-quality water-soluble basepaint system based on special PU dispersions.

The basepaint for pearl effect/heliochrome two-coat paintwork or pearlescent three-coat paintwork can be used on passenger and work vehicles.

Properties:

• Easy to process
• Good stability under load
• High covering capacity
• Can be painted over with two-part HS clear coat
• VOC compliant

Note

After painting over with two-part HS clear coat it produces a high-gloss, weatherproof top coat.

Application Instructions

Base Surface

Suitable base surfaces:

• Intact old paint
• Primed and filled surfaces (two-part HS filler)
• with One-Part Wash Primer -LVM 044 007 A2-/-LVM 044 171 A2- insulated base surfaces
• with Two-Part Plastic Adhesive Filler -LKF 696 009 A2-/-LKF 696 040 A2- insulated base surfaces on plastic surfaces
• See special instructions.

Pre-treatment of base surfaces:

• Clean the factory or old paint or two-part HS filler thoroughly with Silicone Remover -LVM 020 000 A5- or Silicone Remover, Long -LVM 020 100 A5-.

• Dry-sand with rotary sander and dust extraction, P400-500 grit.

• Or "wet"-sand with P800-1000 sandpaper.

• Use a suitable cleaning agent before reworking to ensure a clean and residue-free surface.
• Wipe off any residual silicone remover with a lint-free cloth, leaving no streaks.

Special Instructions

• Sanded-through areas must be insulated with One-Part Wash Primer -LVM 044 007 A2-/-LVM 044 171 A2-. The sanded-through areas should not be larger than 5.0 cm in diameter.
• When using the two-part HS filler, any bare areas must be insulated with Two-Part Wash Primer -LHV 043 000 A2- or One-Part Wash Primer -LVM 044 007 A2-/-LVM 044 171 A2-.

Processing

Mixing vessels:

• Plastic containers or tin-coated cans painted on the inside

Strainers:

• Filter watery base paint through water-tight, 125 um strainers before working with cup systems

Thinner:

• Aquaplus Purified Water -LVW 010 000 A5- (according to ISO 3696)
• Use an Aquaplus measuring stick.
• An addition of 0 to 5 % Purified Water -LVW 010 000 A5- is sufficient at higher temperatures (>+25 ºC (77 ºF) ) and a high relative humidity (> 60 %).

Pre-painting:

• With three-coat pearlescent color shades, a special base surface color is required (for applying solid water-based base paint). Each color shade should be determined using the formula information system.
• For pearlescent paints, apply pearl effect water-based base paint.

Application type "coat"

• Processing viscosity at +20 ºC (68 ºF) material temperature is the mixing viscosity for "Compliant" and "HVLP".

• Add 10 % thinner at +20 ºC (68 ºF) material temperature.

• Set spray nozzle (see manufacturer's information): "Compliant" 1.2 to 1.3 mm.
• Set spray nozzle (see manufacturer's information): "HVLP" WSB/1.3 mm.
• Set spray pressure (see manufacturer's information): "Compliant" to 2.0 to 2.5 bar.
• Set atomizing pressure (see manufacturer's information): "HVLP" 0.7 bar.

• An application includes: applying a thin spray application and then a normal spray application. For color shades with special effects, we recommend a "finishing application".

Note

• For less opaque colors, it may be necessary to apply additional spray applications after the corresponding ventilation time.
• The layer thickness (including base surface color shade solid water-based base paint) should not exceed 45 um.

Drying

The ventilation time for clear coat application is at +20 ºC (68 ºF) room temperature for 20 minutes.

For smaller surfaces, the following make it possible to reduce the ventilation time:

• The painted surfaces can be applied more quickly by blowing them with blower nozzles (hand blowers or with stationary devices).
• Blowing with a spray gun is also possible after waiting at least five minutes.

For larger surfaces, the following make it possible to reduce the ventilation time:

• The painted surfaces can be applied more quickly by using stationary blowing devices (such as ceiling systems), infrared radiators or oven drying.
• Ceiling system 10 to 15 minutes
• IR drying 3 to 5 minutes
• Cooling time a minimum of 5 minutes

Heated drying at +60 ºC (140 ºF)

• Combination booth at least 10 minutes including heating time
• Drying-oven at least 5 minutes.
• Cooling time a minimum of 5 minutes

Note

The evaporating and drying times specified here depend on the temperature, humidity, air sink speed in the spray booth and the number of spray applications. However, you must wait for painted surface to be applied completely.

Reworking

Can be painted over with:

• Two-part HS clear coat from the Volkswagen original paint product line

Special Instructions

Note

• The decision to use two or three coats (with a special base surface color shade), depends on the factory paint.
• Each base surface color tone is indicated in the formula information system.

Touch-up system (for attaining an optically perfect color shade transition to the adjacent parts)

Preparation:

• Sand the filled areas (dry with P400-500 or with water-proof P800-1000 paper).
• Thoroughly sand the adjacent surfaces with a fine sanding pad.
• Clean the entire surface thoroughly with Silicone Remover -LVM 020 000 A5- to remove dust, sanding residue and other dirt.
• Wipe off any residual silicone remover with a lint-free cloth, leaving no streaks.
• Allow wet-sanded surfaces and cleaned surfaces to dry completely.

Two-coat pearl effect/heliochrome color shades:

• Thoroughly cover the filled areas with pearlescent/heliochrome water-based paint which has been prepared for spraying.
• Expand the scope of each subsequent spray application. This overlapping results in only one misted zone.
• Expand the run-off area and touch-up with reduced pressure.
• After an appropriate final ventilation time, paint over with two-part HS clear coat.

Three-coat pearlescent color shades:

• Thoroughly cover the filled areas with solid water-based paint (see using base surface color shade) and touch-up with reduced pressure (keep track of the drying time).
• Using pearlescent water-based paint which has been prepared for spraying, spray the same area again (with reduced pressure) and match it with the original.
• Blow dry with the pistol after each spray application.

Using the products

• The spray devices should be suitable for use with water-soluble products; see manufacturer's information.
• The mixing paints in this top coat series can only be used within the color tone formulas. When processing individual mixing paints on their own, major deviations from the information given in the application instructions are possible.

Cleaning the tools

• Rinse before and after using with Aquaplus Purified Water -LVW 010 000 A5-. Then rinse with Nitrocellulose Thinner -LVE 856 000 A3-.

Disposal

• Collect liquid waste from water-soluble products and separate from liquid waste from conventional products. When mixing materials, disposal may no longer be possible, which is difficult and costly.

Personal Protective Equipment:

• Note the safety data sheets
• Wear the personal protective equipment during application
