Technical data sheet

Substrate

Suitable substrates:

Surfaces coated with primer or surfacer 2-pack HS Vario surfacer -LGF 786 004 A4-, grey

Factory paint or old paint (except thermoplastic paint)

Substrate pre-treatment:

Thoroughly clean factory or old paintwork with silicone remover -LSW 019 000 A5-. If severely soiled, pre-clean the paintwork with slow-drying silicone remover -LVM 020 100 A5-.

Dry sand using orbital sander with P1000 to P1500-grain sandpaper and dust collector.
Sand spokes, corners and edges by hand using P300-grade ultrafine emery pad.

Before recoating the lightly sanded substrates, thoroughly clean them of dust, sanding residue and other dirt withsilicone remover -LSW 019 000 A5-. If severely soiled, pre-clean +with slow-drying silicon remover -LVM 020 100 A5-.

Application

Substrate pretreatment (sanding before surfacer coat)

When 2-pack HS Vario surfacer -LGF 786 004 A4- is to be used, bare-metal spots must be primed with 2-pack wash primer -LHV 043 000 A2-.

A uniform substrate without bare metal spots is absolutely essential.

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

Wet sand with P800 to P1000-grain sandpaper.

Clear coat over surfacer:

Apply 2-pack HS clear coat to the sanded surfacer. Depending on the size of the repair area or if there are several repair areas, it is recommended to apply 2-pack HS clear coat to the entire rim.

Apply a full coat (approx. 20 µm).

Force drying at +60 °C material temperature in 20-25 minutes.

Sanding before clear coat:

Dry sand using orbital sander with P1000 to P1500-grain sandpaper and dust collector.
Sand spokes, corners and edges by hand using P300-grade ultrafine emery pad.

Cleaning:

Before recoating the lightly sanded substrates, thoroughly clean them of dust, sanding residue and other dirt withsilicone remover -LVM 020 000 A5-.

Base coat application “spray”

Materials suitable as additives:

Additive for Aqua premium -LVM 035 301-

Application viscosity 4 mm, +20 °C, DIN 53211
The application viscosity of 4 mm at +20 °C is the mixing viscosity for “Compliant” and “HVLP”.

50 % of additive for Aqua Premium -LVM 035 301- (to be added at material temperature of 20 °C).

Adjust spray nozzle following manufacturer's instructions to 1.2-1.3 mm for “compliancy”.
Adjust spray nozzle following manufacturer's instructions to 1.2-1.3 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”.

One application consists of one-and-a-half spray coats (one normal full coat followed by a light coat at greater distance to object).

Note

The best results are achieved when using an HVLP spray gun with 1.3 mm nozzle.

Blending additive for Aqua Premium -LVM 035 200 A3-/-LVM 035 301 A3- should be added to metallic waterborne base coat -LWG 056 1H7 A1- immediately before application Best results will be achieved if the mixture is applied within one working day.

Drying

Flash-off time before clear coat application:

Flash off at +20 °C ambient temperature until matt.

Note

The best results are achieved when using an HVLP spray gun with 1.3 mm nozzle.

Additive for Aqua Premium -LVM 035 301- should be added to metallic waterborne base coat -LWG 056 1H7 A1 silber- immediately before application. Best results will be achieved if the mixture is applied within one working day.

Ways to reduce flash-off time:

Surface matting can be accelerated by blowing on it with an air diffuser or force drying with infrared radiation or low baking. It is also possible to blow on it with the spray gun after waiting at least 5 minutes.

Drying 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 (elasticized)

Special notes

Note Blending in with metallic waterborne base coat -LWG 056 1H7 A1- is done in 1 or 2 normal spray coats. Apply blending additive for Aqua Premium -LVM 035 100 A3- to the fade-out area.

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.

Personal protective equipment:

Adhere to the safety data sheet.

Wear personal protective equipment during application.
