Fast, informative application notes

Graphic presentations of the various product applications an repair processes, so-called pictograms, allow language. neutral, fast and understandable explanation of the technical data and the product and application information. The most important and standard pictograms for the 2K PRO system are stated below, including the relevant explanations.


We provide answers

2K PRO is a professional, technical system for professionals. Despite product descriptions or extensive technical process descriptions, some questions remain unanswered. The following shows the most frequently asked questions in the past and our answers. If you cannot find an answer to your question here, just contact us. We will be happy to answer your questions!

A spray can should be used until no more product comes out when the spray head is actuated comes, only then is the can completely emptied. Empty spray cans are collected via the recycling facility (Yellow sack, container for light packaging e.g.) recycled. Cans with contents are to be disposed of as hazardous waste.

This is the time between several spray coats over the same point. Often, 2-3 spray coats are required to create a flawless film and closed paint surface. Pauses between applying the spray coats are necessary to allow the propellants in the paint to dissolve on the object (see the pictogram on the can). See also, the explanation of the pictograms.

A clear clicking noise can be heard when the white release button is pressed to trigger / activate the can. (The trigger mechanism has opened/pierced the self-contained hardener cartridge) Another tip: Once the can has been activated, the pressure resistance of the outer trigger pin on the base of the can is also lower, and can be pressed in a few millimetres.

Only partially. Lower temperatures reduce the reaction time of the hardener. No precise time can be stated because, depending on the hardener and various temperature ranges, there are very many different variables that can impact on the process. It is always recommended keeping cans away from direct sunlight and, once activated, storing them in cool but frost-free conditions. If you want to use the cans on more than one object, we recommend jotting down the precise activation date on the can (hour / minute / day).

This is the time from when the hardening cartridge is activated through to the time when the triggered chemical reaction (hardening) prevents further processing. The mixture of product and hardener has hardened inside the can and it can no longer be sprayed. There are various processing times depending on the product and hardener.

Do the following to be on the safe side: Turn the can upside down, and empty the dip tube and valve by pressing the spray nozzle twice. Shake the can again for approx. 2 minutes. Observe the waiting time and then start the painting process. Test spray first so that the air is removed from the dip tube and valve, and ‘spitting’ is avoided. Note: The processing time starts after activation and is not prolonged when used as described.  

This is not a big problem. You can shake the can after activation, however shake for 4-5 minutes instead of just 2 minutes. If possible, directly after activation. The long shaking process ensures that the product / hardener / propellant are all mixed homogeneously. Please observe a waiting time of 15 minutes after shaking. The chemical reaction starts.

Yes, shake them before activation so that the propellant and product mix. After activation, shake again for 2 minutes so that the hardener can be mixed with the product and the propellant. The shaking time must be observed.

It may not have been correctly shaken, shake again for 2 minutes. Paint spray can or the content is possibly too cold. Bring the spray paint can to the recommended processing temperature. There may be product components left in the riser tube and valve. Turn the spray paint can upside down and spray twice so that the propellant releases the residues and transports them to the outside.

Might the spray paint can be empty? Shake until the mixing balls can be heard.
Might the valve be clogged? Wipe all residues from the spray head nozzle, turn the spray paint can upside down and spray twice briefly.

The optimum painting temperature (ambient temperature) with aerosol cans is approx 15-25C° and approx. 40-80 % relative humidity. At low temperatures the spray paint cans should be tempered slightly. This is necessary for the application behaviour.

By the weight of the can and the audible mixing balls in conjunction with the production date that is stated in a code on the base of the can, on the knurled edge of the can or in the can dome. The shelf life of a 1K aerosol can is 5 years, the shelf life of a 2K aerosol can is 3 years. Please send us the product designation and, if possible, the item number and code so we can establish this.

The application starts outside the processing surface. It is applied completely across the surface and the spray coat ends outside the actual processing surface.

Pot life / processing time for the 2K spray paint can refers to the time that is available once the separate, integrated, closed hardener cartridge has been triggered. The processing time depends on the product and hardener components. The pot life is stated on the spray paint can with a pictogram. The processing time depends on the (ambient) temperature. Colder temperatures prolong the processing time, warmer temperatures will shorten the pot life. A chemical process is started on activation. The product can no longer be used after the processing time has expired.
