Ruggedization Notes
• Parylene C coating can be used for conformal coating with a 1.0 mil ± 0.2 mil thickness through a deposition process.
o It has a 5600 VPM rating, withstands temperatures of 350°F, and is extremely resistant to oil/dirt, and object impact.
• Contact COTSWORKS for all MSDS, detailed case composition, and burn analysis.
