Just as a quick summary, cobwebbing is one of the most common processing issues that PCB manufacturers face when conformal coating. It is caused in general by premature drying of the coating as it is atomized and sprayed. It can be solved using a number of approaches designed to slow down the drying process. While challenging, methods to eliminate cobwebbing are fairly straightforward and have been tested and proven to last.

What is PCB Surface Energy and How Does It Affect Conformal Coating
Surface chemistry is an enormously complex and cussed branch of the sciences; consequently, we will attempt only a layman's discussion and understanding here. For the purposes of conformal coating, surface energy must be considered for both the exposed surface of the PCB as well as for the coating itself.

To Clean or Not To Clean Before Conformal Coating
In the days before surface mount printed circuit assemblies, components (such as resistors, diodes, and capacitors) were axial, and printed circuit board components were installed with the “through-hole” method using large conductor spacing. With the advent of integrated circuits, these too were through-hole with good spacing between legs.
