Hydrophobic FR4 Coating

Aculon’s hydrophobic FR4 coating treatments bond to FR4 surfaces to provide an easy clean, anti-smudge finish. Aculon’s innovative hydrophobic coating technology is very simple to apply and requires no significant expenditure on complex equipment. Aculon’s hydrophobic FR4 treatments deposit uniform nanoscale layers onto FR4 surfaces, forming a resilient coating which immediately begins repelling water, dust, oil, and dirt from the surface. In some cases Aculon’s hydrophobic treatments are also oleophobic and repel both oil and water.

Oleophobic FR4 Treatment

Aculon’s range of oleophobic FR4 coating technologies bond with most FR-4 type surfaces. The oleophobic FR4 treatments coat FR4 surfaces with efficient oil resistant and anti-smudge performance enhancing layers that repel water and most other liquids as well as oil.
