One-Part Anti-Corrosion Wash Primer

Definition:

One-Part Anti-Corrosion Wash Primer -ALN 002 003 10-

Edition 06/2011

Product Description

One-part anti-corrosion primer is a zinc chromate-free, polyvinylbutyral-based, single-component product for vehicle repairs. With its special pigment and binder composition it provides excellent protection against corrosion, outstanding adhesion and is also certified for welding. Nevertheless, this product non-conductive and therefore not suitable for spot-welding. For residual rust spots on corners and edges as well as bare-sanded areas, we recommend recoating using One-Part Anti-Corrosion Wash Primer -ALN 002 003 10- with a Two-Part HS Filler.

Application Instructions

Base Surface

Suitable base surfaces:

Cleaned and sanded, galvanized/electrolytically zinced sheet steel or soft aluminum

Sanded factory primer

Hardened, solvent-resistant, well-preserved and sanded old paint or factory paint (with the exception of thermoplastic paint)

Surfaces prepared with two-part polyester products and then sanded very fine.

Pre-treatment of base surfaces:

Carefully clean using Silicone Remover -LVM 020 000 A5- or Silicone Remover, Long -LVM 020 100 A5-.

Dry-sand with rotary sander and dust extraction, P400-500 grit.

Wet-sand with P800-1000 grit sandpaper. Thoroughly remove any potential rust spots and sand any transitions to old paint.

Processing

Dilutable with:

Two-Part Thinner -LVE 009 001 A5-

Two-Part Thinner, Plus -LHA 014 000 A5-

Two-Part Thinner, Special -LVM 009 200 A2/A5-

Application type “coat”

Processing viscosity 4 mm for +20 °C, German Industry Standardization 53211

Adding 40 % thinner at +20 °C material temperature.

Use a measuring stick to mix when pouring in the thinner.

Processing viscosity 4 mm gravity feed spraygun “Compliant” and “HVLP”:

DIN 4 mm: 18 to 20 seconds.

ISO 4 mm: 44 to 53 seconds.

Set spray nozzle (see manufacturer's information): “Compliant” and “HVLP” to 1.3 to 1.4 mm.
Set spray pressure (see manufacturer's information): “Compliant” to 1.5 to 3.0 bar.

Apply two coats.
The prescribed layer thickness is 15 to 20 µm.

Application type “painting”

Note For application type “painting”, apply the material all at one time and do this 1 to 2 times. This ensures that the delivery viscosity will be the same as the processing viscosity.

Drying time: at +20 °C room temperature for 15 to 25 minutes.

Reworking

Recommended structure:

Fill with Two-Part HS Filler. Refer to → Chapter „Filler“.

Caution

Do not rework with polyester products.

Do not rework with epoxy products.

Do not directly rework with water-based base paint.

Do not apply to thermoplastic coatings.

We recommend the following three-layer structure:

Prime with One-Part Anti-Corrosion Wash Primer -ALN 002 003 10-

Insulate with Two-Part HS Filler

Top coat finish

The three-layer structure is essential for galvanized base surfaces.

Personal Protective Equipment:

Note the safety data sheets

Wear the personal protective equipment during application
