Where to Buy Parylene

Posted by Sean Horn on Fri, Jul 28, 2017

Materially, parylene is the most distinctive of the major conformal coatings.  But just how does it differ from liquid coatings — acrylic, epoxy, silicone and urethane??

Batch Size Considerations for Parylene Production

The parylenes consist of a range of para-xylylene polymers whose desirable physical and electrical properties support expansive utilization as conformal coatings for electronic and medical devices  Parylene films are applied to substrates via a chemical vapor deposition (CVD) process, which deposits monomeric parylene vapor homogeneously and deeply into the surface of printed circuit boards (PCBs

Is Parylene Safe?

Application of parylene’s xylylene monomer employs a chemical vapor deposition (CVD) process implemented under a vacuum.  Unlike wet coating application methods – brushing, dipping, spraying, etc. – parylene CVD is not line-of-sight.  Because the vaporous monomer envelopes all sides of the assembly being coated, appropriate process control allows vacuum deposition of an entirely conformal
