Coating Process

diX is applied using a specially designed chemical vapor deposition (CVD) machine. This machine consists

of 3 primary components: a Vaporizer, a Pyrolizer, and a Deposition chamber.

diX dimer, in its original powder form, is placed in a metal boat in the Vaporizer, and the item(s) to be coated

is placed or fixtured in the Deposition chamber.

The diX dimer is vaporized at approximately 120-180 , and the dimer gas is drawn into the Pyrolizer,

where it is heated to approximately 650-700 and converted to a monomer gas.

The vacuum pump then draws the monomer gas into the Deposition chamber, where it is cooled to room

temperature upon contact with the surface of the item(s) inside, and polymerizes into a high molecule

Poly-para-Xylylene film on the surface.

Dimer

Dimer is parylene material being used for coating process. There are many types of dimer with different

properties. For example, Parylene C coating is the coating that used parylene dimer diX C.
