Moisture & Gas barrier, corrosion resistance

Due to the unique structure and deposition process of parylene, it is an excellent moisture and gas barrier.

Kisco's diX coating is widely used to protect substrates from moisture, humidity, various types of solvents, oxidization, and development of rust.

Below we've coated half of a metal sample slide with diX parylene. After a 24 hour salt spray test the coated side remains unchanged, but the uncoated side is extremely corroded. Parylene provides an excellent barrier from moisture and corrosion, which is extremely beneficial for products exposed regularly to ‘harsh’ environments.

Due to an extremely low moisture permeability rate, Kisco coatings prevent the ingress of water, even protecting this bare LED board when totally submerged... it still works!
