One-Part Anti-Corrosion Wash Primer

Definition:

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

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 ºC (68 ºF), German Industry Standardization 53211

Adding 40 % thinner at +20 ºC (68 ºF) 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 um.

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 ºC (68 ºF) room temperature for 15 to 25 minutes.

Reworking

Recommended structure:

• Fill with Two-Part HS 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

Application Instructions

Base Surface

Suitable base surfaces:

• Steel
• Cleaned and sanded, galvanized/electrolytically zinced sheet steel or soft aluminum
• Sanded factory primer (not on large areas of new parts that have been sanded and coated with KTL primer)
• Thoroughly sanded old primer or factory primer (excluding thermoplastic coating)
• Surfaces prepared with two-part polyester products and then sanded very fine.

Note

Because of the wide variety of alloys and manufacturing processes for metals, the base surface must first be tested to ensure that the pre-treatment provides sufficient adhesion.

Pre-treatment of base surfaces:

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

• Clean and sand factory or old paint, eliminate any potential rust areas, and sand transitions to old paint.

• Use a suitable cleaning agent before reworking to ensure a clean and residue-free surface.

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-
• Two-Part Thinner, Long -LVM 009 300 A2- (for large objects and high temperatures)

Application type "coat"

• Processing viscosity 4 mm for +20 ºC (68 ºF), German Industry Standardization 53211 is the mixed viscosity.

Adding 50 % thinner at +20 ºC (68 ºF) 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: 36 to 45 seconds

• Set spray nozzle (see manufacturer's information): "Compliant" and "HVLP" to 1.3 to 1.5 mm.
• Set spray pressure (see manufacturer's information): "Compliant" to 2.0 to 2.5 bar.
