A method for depositing Parylene onto a substrate includes operating a first pyrolysis chamber at a first set of parameters to cause cracking of dimers into monomers at the first set of parameters and operating a second pyrolysis chamber at a second set of parameters to cause cracking of dimers into monomers at the second set of parameters. The method includes mixing the monomers at the first set of parameters with monomers at the second set of parameters together and polymerizing the mixture as a protective coating.
