	The silver conductive paint from Less EMF: [http://www.mgchemicals.com/products/842.html MG Chemicals 842-20G)], is extremely viscous and expensive (about $30 for 0.7 oz or 20 g). Hence we decided to thin the paint by diluting it with household chemicals rather than purchasing a specialized paint thinner as recommended by many manufacturers. Neither water nor rubbing alcohol (iso-propanol), both of which are polar protic solvents, worked for diluting this paint. The polar aprotic solvent acetone, on the other hand, did work. We didn't try any nonpolar solvents like butyl acetate, because they weren't readily available.

Hence we decided to thin the paint by diluting it with acetone rather than purchasing a specialized paint thinner as recommended by many manufacturers.

==Chemicals in Conductive Paint Thinner==

The choice of thinner depends on the medium, in which the conductive metal particles are suspended.

* Water - good for latex based paints and recommended for thinning [http://www.semicro.org/index.asp?PageAction=VIEWPROD&ProdID=2 SE Micro Silver Paint]

* Alcohol - similar to water, but faster to dry. It's recommended for thinning [http://www.semicro.org/index.asp?PageAction=VIEWPROD&ProdID=2 SE Micro Silver Paint]
