Top quality filling and insulating two-component acrylic primer for car body repairs
AKRYL EXTRA primer is characterised by very good adhesion to steel, aluminium, galvanised steel, polyester putties, epoxy and reactive primers and well-sanded varnish coats. It is easy to mix and apply. After spraying, it remains stable on vertical surfaces. It can be used for most body and paint repairs
The above application instructions are recommendations based on the tests performed and our experience. We recommend performing your own tests before you use the product. Due to the wide variety of applications as well as storage and working conditions, we cannot accept any responsibility for the results of work in a particular application. Our customer service department makes technical information or advice available free of charge, however, these services are provided without liability, unless the information is provided under a concluded contract or the consultant is acting for a specific purpose. We guarantee the uninterrupted quality of our products. We reserve the right to make technical changes and to upgrade our products.
Before applying the primer, the surface should be carefully sanded with sandpaper with the following gradation:
- manual sanding (dry or wet): P280 – P320
- machine sanding (dry): P180 – P220
Preferably use a 1.8 nozzle with a ratio of 5:1 + 25% of Würth thinner art. 0823 410 001. For most repairs 2 coats are sufficient, if necessary up to 3 coats can be applied for a total of 300 µm. The second coat is applied after 7-10 minutes and the third coat is applied after about 30 minutes under normal conditions. The primer becomes matt; if shiny areas are visible, wait a few more minutes for the thinner to evaporate. The optimum drying temperature is 18-20°C! Below this temperature the curing time increases considerably and at temperatures below 8°C the chemical curing process stops.
Curing time at 20°C:
- Filling primer /130÷300 μm/ ready for sanding after overnight drying
- Primer /60÷130 μm/ ready for sanding after 3÷4 h
Curing time at object temperature 60°C:
- Filling primer /130÷300 μm/ ready for sanding after heating for 35÷40 minutes and cooling the coat (about 2h)
- Primer /60÷130 μm/ ready for sanding after heating for 25÷30 minutes and cooling the coat (about 2h)
Please note that the cabin drying times are given for the cabin and the heated material. Example of 30 min at 60°C means heating the cabin for 10 min, then the metal sheet for 5 min and from then on 30 min. In order to speed up the drying process, the IRT radiator should only be placed after approx. 10-15 minutes
The primer is easy to process - mechanical sanding with sandpaper grading from P320 to P500
