There is actually a great deal of science, chemistry and research behind hydrographic dipping starting with the most important; "Chemicals"
The first chemical compound to know about is (CH2=CB02CCH3)
Polyvinyl Acetate (PVAc), a synthetic resin prepared by the polymerization vinyl acetate. In it's most important application, polyvinyl acetate serves as the film-forming ingredient in water-based (latex) paints; it also is used in adhesives.
Vinyl acetate (CH2=CHO2CCH3) is prepared from the ethyleneby reaction with oxygen and acetic acid over a palladium catalyst. Under the action of free-radical initiators, vinyl acetate monomers (single-unit molecules) can be linked into long, branced polymers. There are an array of chemical measurements and combinations used throughout the hydrographic process. The activator, in my opinion is the most crucial. it is like the fuel in my 97 Harley Davidson in the since that no matter what else I do to her, no matter how I build or customize her, she just is not going to work right for me if I don't give her the right fuel in the right amount at the right time. It is the same concept for hydrographics. In-addition to using the correct ratio of chemicals used to activate the hydrographic film the artist must be able to visually identify the correct time to apply the activating chemicals which can vary from 60 to 110 seconds depending on the PVA levels of each individual film pattern. If the artist over applies or does not apply enough the chemical ratio will be incorrect and the dip will fail therefore the activation process (in my opinion) is the most crucial piece to hydrographic dipping success.
H2 O The transfer of an image to a 3d object requires specific temperature and pressure to adhere the pattern to the object. Using precise water temperatures and skilled submersion techniques a seasoned hydrographic artist will submerge, angle and rotate the object in a manner that allows the water to apply pressure correctly to each individual dimension as if it were a single dimension without distortion of the image or pattern being transferred.
