Description
The generic name for a series of polymers based on paraxylylenes. Parylene is unique in that it can be vapor polymerized to form a thin continuous coating on a surface. Parylene adds mechanical strength and flexibility to the coated material. Parylene coating is irreversible and not lightfast. It cracks, flakes and discolors with age.
Synonyms and Related Terms
paraxylylene; parileno (Esp.); Parylene C; Parylene N
Physical and Chemical Properties
