Technical data sheet

Substrate

Suitable substrates:

Steel

Cleaned and sanded electroplated or roller-galvanised steel panels or soft aluminium

Lightly sanded factory primer (not for large surfaces of lightly sanded electrophoretic primer of new parts)

Well-sanded factory paint or old paint (with the exception of thermoplastic paint)

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

Note Owing to the wide variety of metal alloys and manufacturing processes, it is essential to carry out a preliminary test on the respective substrate to ensure that the pretreatment is sufficient to guarantee perfect adhesion.

Substrate pre-treatment:

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

Clean and lightly sand factory paint or old paint, completely remove any rust spots and sand feather edges to the old paint.

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

Application

Thinner:

2-pack thinner -LVE 009 001 A5-

2-pack thinner plus -LHA 014 000 A5-

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

2-pack thinner, slow-drying -LVM 009 300 A2- (for large objects and high temperatures)

Method of application: “spray”.

Application viscosity 4 mm, at +20 °C, DIN 53211 is the mixing viscosity.

Add 50% thinner at a material temperature of +20 °C

If thinner is added, use measuring stick to mix.

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

DIN 4 mm: 18-20 seconds

ISO 4 mm: 36-45 seconds

Adjust spray nozzle following manufacturer's instructions to 1.3-1.5 mm for “compliancy” and “HVLP”.
Adjust spray pressure following manufacturer's instructions to 2.0-2.5 bar for “compliancy”.

When using as wash primer, apply one spray coat.
The specified thickness for the dry film is 10-15 µm.

Note Small bare-metal spots may be isolated using waterborne base coat or 2-pack HS top coat only with wet-on-wet application or with intermediate sanding on top of 1-pack wash primer -LVM 044 007 A2-/-LVM 044 171 A2- if the bare-metal spot is not greater than 5.0 cm in diameter.

Flash-off time at +20 °C ambient temperature, recoat after:

10-15 minutes with 2-pack HS surfacer.

20-30 minutes with waterborne base coat (only for small bare-metal spots)

10-15 minutes with 2-pack HS top coat (only for small bare-metal spots)

Dry for sanding in 45-60 minutes

Recoating

Application	Recoat with
As wash primer	2-pack HS surfacer
as wash primer with intermediate sanding	Wet sand with P800 to P1000-grade paper

Recoat with:

Waterborne base coat and 2-pack HS clear coat (only for small bare-metal spots).

2-pack HS top coat (only for small bare-metal spots).

Caution

Do not recoat with polyester products.
