Encrustation Prevention

Parylene conformal coatings offer a unique combination of protective properties that few other materials can match. Applied via chemical vapour deposition, these pinhole-free polymer films deliver outstanding corrosion resistance against moisture, chemicals, and salt spray, making them a trusted solution for electronics in harsh environments. Their excellent dielectric properties provide reliable electrical insulation even at film thicknesses of just a few micrometres. In medical and implantable device applications, parylene significantly improves biocompatibility, creating an inert barrier between the device surface and surrounding tissue or bodily fluids. The coating's inherently low coefficient of friction reduces mechanical wear on moving parts and sliding contacts, extending component lifetime. Finally, parylene's dense, non-porous surface structure effectively prevents encrustation — the buildup of mineral deposits or biological matter — a critical advantage in urological, cardiovascular, and fluid-handling applications.
