Product catalog summary
Product Overview: The P 411 Wet on Wet Primer is a high-quality acrylic sealing primer designed for 'wet on wet' applications, providing excellent adhesion on new surfaces without the need for sanding. It is VOC compliant and suitable for professional use.
Specifications: The primer is mixed in a 4:1 ratio with H 729 Hardener for Primers Normal. A 25% addition of thinner/reducer (740 Acryl Normal or 741 Acryl Slow) is required. The pot life is 60-80 minutes at 23°C (73°F), and it is ready to spray at 16-18 seconds DIN 4 at 20°C (68°F). The recommended spray gun nozzle size is 1.3-1.4 mm with an inlet pressure of 2-2.5 bar (29-36 psi) for compliant spray guns and 1.5-2 bar (22-29 psi) for HVLP. The coat thickness should be 15-25μm (0.6-1.0 mil).
Application Procedures: For metallic surfaces, apply one coat as 'wet on wet'. For plastic bumpers and parts, use 340 Plastofix instead of thinner/reducer. Unsanded plastic parts require a 25% addition of 340 Plastofix. Ensure surfaces are clean and dry before application. The primer can be recoated wet on wet with basecoat and clearcoat or 2K PUR paint after a final flash-off time of 20-30 minutes at 23°C (73°F).
Surface Pretreatment: Clean substrates using a soft cloth and 770 Antisil Normal or 771 Antisil Fast Degreaser. For bumpers, slightly abrade with P600-P800 wet. Ensure surfaces are wiped dry and air-dried before application.
Safety and Handling: Always wear protective equipment and ensure good ventilation. The product contains isocyanates, which may cause skin sensitization. Equipment must be moisture-free as 2K paint systems react with water.
Storage and Shelf Life: Store in a cool place (5°C to 25°C) and use within 12 months for best results. The guaranteed shelf life is 24 months in unused original containers.
Additional Information: The primer is not recommended for use over Body Wash Primers or P961 Etch Primer. It is suitable for use in countries that do not adopt VOC legislation. The theoretical coverage is 8 m²/l at 15 microns dry film thickness. Clean equipment after use with 740 Acryl Normal Thinner/Reducer.
