Description
Aluminium Silicate is a synthetic mineral produced from coal fired power stations as a slag and then cooled immediately in water to form a glass type substance.
Aluminium Silicate is a general purpose abrasive to be used in blast pots with an open nozzle and not in a blasting cabinet. It can be used on a variety of materials including, steel, wood, and brick. It is softer then iron silicate and lighter in colour hence preferred for brick, stone and wood work, including oak beams, as it leaves less of a dark residue when blasting.
Examples – Keyalum0/5 (0.09 – 0.25mm) is ideal for car panel work where the metal is thin and therefore needs a lesser abrasives material – this grade would also be used on stone work with and oak beams (not green oak see calcium silicate)
For materials with lots of layers of paints a coarse grade would be better.
We suggest that one 25kg bag will do roughly 1msq.
The blasting nozzle ideally needs to be 3x the size of the largest particle of grit for the abrasive to flow freely.
