Product description
The Aqua Premium system is an innovative waterborne base coat system. All solid and effect colours for passenger car refinishing can be mixed from this system.
Properties:
Fast, easy to use system
Very reliable results thanks to uniform effect formation
Short process times
Easy and reliable blending
Versatile in use (interior, multi-stage and multi-colour finishes)
Technical data sheet
Substrate
Suitable substrates:
Surfaces coated with primer or surfacer (2-pack HS surfacer)
Intact old paint
For plastic surfaces: adhesion promoter (transparent) -ALO 822 000 10- + 2-pack HS surfacer (elasticised)
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-.
 

Aqua Premium system

–  Dry sand using orbital sander with P500 to P600-grain sandpaper and dust collector.
 

Aqua Premium system

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

Aqua Premium system

–  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 for standard applications
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.
Additives:
(at normal or high temperatures and low humidity depending on size of object)
Additive for Aqua premium -LVM 035 200 A3-
Additive for Aqua premium -LVM 035 301 A3-
Use standard Aqua Premium measuring stick.
  Note
The mixture must be applied within 24 hours after the additive has been added.
 

Aqua Premium system

Method of application: “spray”.
 

Aqua Premium system

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

Aqua Premium system

–  For solid colours, add 10% additive for Aqua Premium -LVM 035 200 A3/LVM 035 301 A3- at +20 °C material temperature.
–  For metallic or pearlescent colours, add 20% additive for Aqua Premium -LVM 035 200 A3/LVM 035 301 A3- at +20 °C material temperature.
 

Aqua Premium system

–  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 bar for “compliancy”.
–  Adjust atomising pressure following manufacturer's instructions to 0.7 bar for “HVLP”.
 

Aqua Premium system

–  One application consists of one-and-a-half spray coats. Apply one normal spray coat followed by a “finish or effect coat”.
  Note
If the paint colour does not hide well, it may be necessary to apply an additional “wet-on-wet” spray coat after an appropriate flash-off time.
 

Aqua Premium system

Drying
 

Aqua Premium system

Continue the flash-off time until the entire surface is matt before applying clear coat.
Recommended coat thicknesses:
Solid colours: 12-25 µm
Metallic colours: 10-15 µm
Pearlescent colours: 15-20 µm
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:
 

Aqua Premium system

Surface matting can be accelerated by using stationary air diffusing units (e.g. ceiling system), infrared drying or low baking.
Application of 3-stage colours and multi-colour finishes
Hardener:
Aqua Premium hardener -LVM 045 000 A1-
Additives:
(at high temperatures and low humidity)
Additive for Aqua premium -LVM 035 301 A3-
Use the Aqua Premium measuring stick for three-stage colours.
  Note
The mixture must be applied within 24 hours after the additive has been added.
Pot life:
Solid colours: 90-120 minutes at +20 °C ambient temperature.
Effect colour: 45-60 minutes at +20 °C ambient temperature.
 

Aqua Premium system

Method of application: “spray”.
 

Aqua Premium system

–  The application viscosity at +20 °C is the “compliant” and “HVLP” mixing viscosity.
–  For three-stage colours, add 5% Aqua Premium hardener -LVM 045 000 A1- only to the base coat
 

Aqua Premium system

–  For solid colours, add 10% additive for Aqua premium -LVM 035 301 A3- at +20 °C material temperature.

Drying
 

Aqua Premium system

Continue the flash-off time without blowing on it until the entire surface is matt before applying clear coat.
Flash-off with an air diffuser is done for 5-10 minutes at +20-40 °C until the entire surface is matt.
The final flash-off time is 10-15 minutes at +60-65 °C. Allow base coat to cool before applying effect coat.
  Note
»Blue contour tape« is recommended for multi-stage finishes.
 

Aqua Premium system

Recoating
Recoat with:
Effect colour.
2-pack HS clear coat up to 72 hours maximum after base coat application
Application of interior finish without clear coat

Special notes
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.
 

Aqua Premium system

Personal protective equipment:
Adhere to the safety data sheet.
Wear personal protective equipment during application.
