Technical data sheet

Substrate

Suitable substrates:

Sheet steel, electroplated or roller galvanized sheet steel or soft aluminium, cleaned, sanded and coated with 2-pack wash primer -LHV 043 000 A2- or 1-pack wash primer -LVM 044 007/171 A2-

Finely sanded or unsanded, thoroughly cleaned, original factory primer

Lightly sanded factory paint or old paint (including thermoplastic paint)

Surfaces prepared with 2-pack polyester products and then finely sanded

Cleaned and sanded UP-GF (fibreglass) surfaces, free of release agents

Substrate pre-treatment:

Thoroughly clean with silicone remover -LVM 020 000 A5- or slow-drying silicone remover -LVM 020 100 A5-.

Then lightly sand.

Before recoating, use a suitable cleaning agent to ensure a clean surface free of residues.

Application

Mixing ratio:

4:1 by volume with:

2-pack HS hardener -LHA 009 041 A3-

2-pack HS hardener, fast-drying -LHA 021 004 A3-

2-pack HS hardener, extra fast-drying -LHA 009 046 A2-

2-pack HS hardener, slow-drying -LHA 009 047 A3-

2-pack HS hardener, extra slow-drying -LHA 009 048 A3-

Mixing ratio:

7:1 by volume with:

2-pack VHS hardener, fast-drying -LHA 009 050 A2-

2-pack VHS hardener -LHA 009 051 A2-/-LVM 009 051 A5-

2-pack VHS hardener, slow-drying -LHA 009 052 A2-/-LHA 009 052 A3-

2-pack VHS hardener, extra slow-drying -LHA 009 053 A2-

For elasticization, see → Anchor

Application time/pot life:

Mixed for spraying, 90-120 minutes at +20 °C.

Thinner:

2-pack thinner -LVE 009 001 A5-

2-pack thinner, slow-drying -LVM 009 300 A2-

2-pack thinner plus -LHA 014 000 A5-

2-pack thinner, special -LVM 009 200 A2/A5-

Method of application: “spray”.

Application viscosity 4 mm, +20 °C, DIN 53211

Application viscosity 4 mm, gravity-feed spray gun “compliant” and “HVLP”.

Add 10% VHS hardener at material temperature +20 °C.

HS hardener is not necessary, but up to 10% may be added.

If hardener is added, use measuring stick to mix.

Adjust spray nozzle following manufacturer's instructions to 1.6-1.8 mm for “compliancy”.
Adjust spray nozzle following manufacturer's instructions to 1.5-1.9 mm for “HVLP”.
Adjust spray pressure following manufacturer's instructions to 1.5-3.0 bar for “compliancy”.
Adjust atomising pressure following manufacturer's instructions to 0.7 bar for “HVLP”.

Three spray coats are necessary to achieve a dry-film thickness of 80-300 µm.

The maximum dry-film thickness for air drying is 300 μm.

The maximum dry-film thickness for force drying is 250 μm.

The maximum dry-film thickness for IR drying is 200 μm.

The maximum dry-film thickness of black paint for IR drying is 180 μm.

The specified thickness for the dry film is 80-200 µm.

Drying

The material can be sanded after 3-4 hours (film thickness of 80-150 µm and air drying at +20 °C ambient temperature). If a film thickness of 150-300 µm was applied, allow the material to dry overnight before sanding.

Final flash-off time with force drying is at least 5-15 minutes.

Force drying at +60 °C material temperature up to 80-150 µm, 25-30 minutes, and 150-250 µm 35-40 minutes.

Final flash-off time with infrared drying is at least 5-15 minutes.

Infrared drying (depending on coat thickness) with medium-wave radiant heater, 15-20 minutes and with short-wave radiant heater, 10-15 minutes.

Further steps

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

Wet sand with P800 to P1000-grain sandpaper.

Recoating

Recoat with:

Waterborne base coat and 2-pack HS clear coat

2-pack HS top coat

Special notes

Elasticization for rigid and semi-rigid plastics:

First mix the base material with 15% elastic additive -ALZ 011 001-. Mixing ratio 3:1 with HS hardeners and no thinner, 4:1 with VHS hardeners and 5% thinner.

Any substrate defects can be treated with 2-pack polyester filler. After drying and intermediate sanding, isolate the filler patches with 2-pack HS premium filler.

When isolating certain spots - even on problem substrates - the best results are achieved with a medium film thickness of 80-120 μm in 2 coats, after either air drying overnight, force drying or infrared drying. With problem substrates, careful pretreatment is imperative, and the surfacer must be applied to the entire surface.

For isolating thermoplastic paint, 2-pack HS Vario surfacer -LGF 786 004 A4-, grey is recommended.

Personal protective equipment:

Adhere to the safety data sheet.

Wear personal protective equipment during application.
