Conformal Coatings Thickness: Comparing Parylene with Liquid Coatings

Posted by Sean Horn on Fri, May 18, 2018

Of the five most commonly used conformal coatings, four – acrylic (AR), epoxy (ER), silicone (SR) and urethane (UR) – are classified as wet materials, meaning they are applied to substrates by three basic types of liquid-based technology:

Parylene Effectiveness at Different Thicknesses

Posted by Sean Horn on Fri, May 4, 2018

Each conformal coating material exhibits a range of unique performance properties that determine its product uses.  Relevant factors include the required coating-thickness necessary to assure reliable performance.  Like other coating types, parylene (XY) layer thickness is largely a function of several factors:  (1) substrate material, (2) the kind of assembly being covered, and (3) its [&helli

Does Parylene De-Wet?

Liquid conformal polymers – resins of acrylic (AR), epoxy (ER), silicone (SR) and urethane (UR) – use wet application processes to attach to substrates.  Most prominent of these are brushing the wet coating onto an assembly, dipping (immersing) the assembly in a bath of liquid coating, or spraying the conformal film onto the designated surface.  […]
