What are pigments combined with to create an Aluminum Pigment Paste?

A variety of solvents can be used to create paste. While the solvent used will depend on the end use, mineral spirit is common. Even water can be used should the paste be needed for water based coatings.

Water based aluminum paste is also used in lightweight concrete. A water and alkaline solution, mixed with aluminum, will give off gasses that result in small air pockets within the concrete. The result is a lighter concrete known as “aerated concrete.”
