Parylene HT/AF4 (CAS No. 3345-29-7)
Parylene finds widespread use in various applications like aerospace, automotive, medical, semiconductor, and electric. It is a polymer that is best-suited for conformal coatings because of its inert nature. Parylene is an excellent barrier coating, and therefore, it has rapidly found use in tiny coating parts, for example, circuit board components.
Parylene AF-4 is the only parylene type that displays a consistent degree of UV-resistance, one wherein performance is maintained relatively long-term. Like the other parylene types, AF-4 also forms an effective, structurally continuous protective film as thin as several hundred angstroms, due to uniqueness of the chemical vapor deposition (CVD) process used to coat substrate surfaces.
Also called aliphatic fluorinate, AF-4 replaces the alpha hydrogen atom of the N dimer with fluorine, and totals 4 atoms. This compositional variation allows AF-4 to generate the lowest parylene coefficient of friction and dielectric constant throughout UV-exposure, and the highest penetrating ability. AF-4 is also useful in high temperature, short-term applications up to 450°C.
