Metal powder - Aluminum
This Aluminum powder consists of 100% Aluminum. Due to its fine composition, this Aluminum powder can be used for mixing in, for example, paints, lacquers, casting resins and plasters. Then you can sand the whole thing and apply a patina.

When processing, pay attention to the weight of the metal powder. Metal will usually sink to the bottom.
With a high addition of metal powder to casting resins or plaster, the end result will become more fragile.
Processing in acrylic resin:
With the A and B component of the acrylic resin in proportion. Add the same weight of metal powder as the weight of the total acrylic resin mixture. For example 1.5 kg. tempered acrylic resin with 1.5 kg. metal powder.
Speed up the rusting process: this can be done with hydrochloric acid or ammonia. (Consider your own safety)
This process can be stopped by rinsing with water or soda.
You can apply a sealer to maintain the effect.
By not applying sealer, the rusting process will continue naturally.
Applying patina: There are many techniques for applying patinas. This often involves working with acids. Think carefully about your own safety and that of your environment! Especially with regard to inhalation and skin contact. If you are not familiar with the safety and processing of these various substances, we do not recommend patination.
