The Parylene coating process

The Parylene coating process is unique in the coating technology. The deposition process of polymers occurs at molecular level and consist three basic steps.

The first step is the vaporization of firm dimer. The dimer is heated to a temperature of 160°C and is dissipated in a gas.

The gas is then pyrolysed (thermo chemical cleavage of organic compounds) to crack the dimer in his monomeric form.

The monomeric gas is deposited in the deposition chamber under room temperature as a transparent polymeric film.

The obtained coating thickness can vary with the application and can amount from 0,2 up to 100 µm pro run.
