Parylene: coatings and applications.

From: Paint & Coatings Industry | Date: October 1, 2006| Author: | Copyright information

Parylene (poly paraxylylene) is a generic name for polymers that belong to a unique chemical family and are used as conformal coatings in protective applications. The coating process exposes product to the gas-phase monomer at low pressure. Through vacuum deposition, parylene condenses on the object's surface in a polycrystalline fashion, providing a coating that is truly conformal and pinhole free.

Compared to liquid processes, the effects of gravity and surface tension are negligible, so there is no bridging, thin-out, pinholes, puddling, run-off or sagging. The process ...

The next evolution of parylene coating: parylene is an excellent option for medical device manufacturers seeking a device coating for their product. Unfortunately, specific factors limit its use in certain applications. A new variation offers benefits that address these concerns. This article examines Parylene HT and the advantages it offers to device makers while addressing these previously limiting factors.(Emphasis On Parylene)
