Its permeability against liquids and gases is second to none where organic polymers are concerned and just one order of magnitude poorer than inorganic. 83 ± 0. Is parylene coating optically clear? Yes, parylene C and N ultra-thin coatings are colorless and transparent. Based on the application requirements. Liquid coatings such as acrylic, epoxy, silicone, and urethane use traditional methods for application to printed circuit boards--brushing, dipping, spraying, etc. The resulting coatings serve as moisture barriers, provide electrical insulation and chemical resistance, and mitigate the catastrophic consequences of corrosion. As an ultra-high solids coating, it adds. 5 x 30. Of the commercially available Parylene variants, Parylene C, Parylene HT® and ParyFree. Electronics process materials. Components such as circuit boards, sensors, metallic wires, wafers, medical devices, and MEMs in sample sizes up to 10in. The post-mortem comparison of (a) parylene N and (b) parylene C behavior during the scratch test for a 8 μm coating revealed that the first cracks were observed at the applied load of 0.
