Surface tension

The behaviour of surface tension is based on how the molecules in the liquid attract each other. Inside the liquid the forces cancel each other out mutually, on the surface they are directed inwards and strive to keep the surface as small as possible. Water has a very high surface tension compared to organic solvents. This has corresponding effects on the coating as well as the atomising energy, the wetting of the substrate, air pockets and foam
