Film splitting cavitation

Our theory behind mist formation is schematically illustrated in Fig. 5. This shows the applicator roller, which is in contact with the paper, thereby transferring the liquid silicone to the paper, generating film split. There exists high pressure at the spot where the applicator roller is in contact with the paper surface. This pressure is released when this contact is lost, which causes cavitation. Bubbles and fibrils are formed. Mist particles will be formed if the fibrils break at several places. If one can make sure that the fibrils break at one spot only, a clean film split takes place and no mist will be formed.
