Here are some main differences between the water and alcohol base conductive paints:-The alcohol base paint dries almost instantly, and the water base one dries similarly to acrylic paint.-The alcohol base paint requires high percentage isopropyl alcohol (90%+) to thin when needed, and any grade of isopropyl alcohol can be used for brush clean up. Thinner is available, or isopropyl alcohol (90%+) may be found at certain local grocery stores or on Amazon/eBay. -The water based conductive paint is water soluble, and requires distilled water for thinning when needed, and tap water is fine for paint brush clean up.
-While both types of conductive paints need to be stirred before use, the water base paint requires VERY thorough stirring from the bottom until smooth with a stir stick(provided in each order) each time you use it, since the conductive particles are heavier than the water and separate to the bottom pretty quickly. -The alcohol base paint needs to be stirred or shaken every once in a while.
-They are both conductive from graphite, yet the water based paint is slightly more conductive than the alcohol based paint, which only means it will achieve the first base/coverage of copper layer slightly faster than the alcohol based paint.
