What causes white board markers to dissipate when writing on dry erase painted surfaces. It almost immediately start to pull together and seems as if it disappears
The issue at hand is competition between the intermolecular forces that pull the solvent together and the forces that cause the solvent to adhere to the surface. In this case, the solvent's interactions with itself are greater, causing the ink to bead. Since the amount of ink that is actually drawn out when writing is very small, the beads of ink are tiny and very hard to see.
