Chemical and Solvent Resistance

KISCO’s diX coating is chemically stable and is not affected by most acids, alkalis, and solvents, which protects the surface of the substrate. This makes it an excellent choice to protect sensors, mechanical parts, and printed circuit boards which are used in severe operating environments.

Half of the transparent acrylic plate below is coated in parylene and immersed in acetone at room temperature for 15 minutes. The acrylic plate is weak to organic solvents, such as acetone, thus the non-coated side is easily eroded and transparency has been lost; however, the diX coated surface looks the same as before, keeping the original transparency and showing no signs of degradation.
