Aluminium Metallic Pigments
- Waterproof Coated Aluminium Powders
Aluminium powders are fantastic due to their shiny silver nature and the fact that they impart excellent hiding power. This is the reason we use them in all our metallic paints. Normal aluminium powders are, however, highly reactive in water and even explode when thrown into water. Aluminium dust can even explode in the air at certain concentrations if an ignition source (e.g. a spark) is provided.
Both the aluminium powders that we sell are coated to make them stable in water (waterproof). Being water stable also means that they will be stable in any arts or crafts you use them in.
- It may be better to describe this paste as solid looking lumps that can be cut with a knife. Some of the lumps are small (like granules) and some large but this makes no difference. Although the lumps may look like solid metal they definitely are not and they can be broken up into individual powder particles in water. The "lumps" can be worked into a powder in water by soaking and pressing them with the back of a teaspoon for example. After doing this the water will look like liquid metal when stirred and the water/aluminium powder mix can be incorporated into water-based paints and other water compatible media.
- Although this aluminium pigment is stable in water it is not stable in all chemicals so once added to a medium (e.g. to a water-based paint) the medium should be used within a few hours. It is stable for storage in paints with certain properties but most paints and mediums need to be used within a few hours.
