1. Bonding strength. Molecular attraction to the substrate surface to which a powder coating is applied.

2. The most stable orientation of the molecular attraction lie along the surface.

3. Molecular attraction between the parts can boggle up the works, according to Columbia University professor Luc Frecheete, one of the engine's designers.

4. Cohesive forces involve the molecular attraction of one constituent to the other.

5. It is foot power, even from the most basic principles of physics in the universe - molecular attraction .
