Technical data sheet

Substrate

Suitable substrates:

Sheet steel, galvanised/zinc-plated 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 A2-/-LVM 044 171 A2-.

Finely sanded, thoroughly cleaned original factory primer.

Lightly sanded factory paint or old paint (except TPAs, thermoplastic acrylics).

Surfaces pre-treated with 2-pack polyester products and then finely sanded.

Cleaned and sanded UP-GF 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-.

Lightly sand old or factory paintwork.
Completely remove any rust spots and sand feather edges to old paint.

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

Application

Activation of 2-pack aerosol can:

Shake before using.

Remove red push button from cap and place on hardener mixing valve on bottom of can.

Press in hardener mixing valve. When pressing down hardener mixing valve, be sure that the can is inverted.

Vigorously shake can for at least 2 minutes.

Application time/pot life:

8 hours at +20 °C

Method of application: “spray”.

Apply in 2-3 full spray coats with 5-10 minutes intermediate flash-off time between individual coats.

Spraying distance:

Maintain a distance of 20-25 cm.
The specified thickness for the dry film is approx. 80 to 120 µm.

Note If spray work must be interrupted, ensure that the nozzle is cleared to avoid clogging by inverting the can and spraying until the valve is empty.

Drying

Air drying at ambient temperature of +20 °C:

3 to 4 hours for dry-film thickness of 80-120 µm.

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

Force drying period at object temperature of +60 °C is 30 to 40 minutes for a film thickness of 80 to 120 µm.

Flash-off time with infrared drying is at least 5-10 minutes.

For a film thickness 80 to 120 µm, the final flash-off time with infrared drying is 10 minutes (short wave) or 15 minutes (medium wave).

Finishing

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:

2-pack HS top coats

Waterborne base coat and 2-pack HS clear coat

Note

Any substrate defects can be treated with 2-pack polyester filler.

After drying and intermediate sanding, treated spots can be isolated again using 2-pack epoxy primer surfacer -LLS MAX 220 M1/M2- or a 2-pack HS Premium surfacer. When isolating (even on problem substrates), the best results are achieved after 2 to 3 spray coats (medium film thickness of 80-120 μm), 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.

Caution Protective garments and equipment in accordance with work safety regulations must be worn. Observe safety information sheets as well as warnings on the label of the spray can.

Shake again briefly before spraying each coat.

After fully emptying the spray can, dispose of as recycling material
