Coating Process

The coating process of Parylene involves the application of Parylene by chemical vapor deposition (CVD).  The HTX process is unique and departs significantly from the current Gorham process.  Instead of beginning with a dimer powder, HTX starts as a liquid monomer which can be mass flow controlled during the process for exact deposition thickness.  A patented unique catalytic process is used to create an active species which is polymerized in a deposition chamber when the product is coated with positive tight controls on uniformity that is easily attained because of a controlled end-point.

HTX Parylene once polymerized onto the base substrate forms a continuous pinhole free film that is truly conformal over even the most complex shapes.  Infinite chain polymers that are highly crystalline create unique protection and dielectric properties and the result is that HTX provides better protection at lower cost.
