Provides an overview of Durasurf (water- and oil-repellent coating)



DURASURFDURASURF<Fluorinated coatings>

Water- and oil-repellent coating

Durasurf coatings can be used to repel oil, to prevent resin adhesion, to prevent flux wicking, and to make textiles water-repellent.

Oil-repellent
Product name Sample Application
DS-1100 Fluid bearings in hard disk drive motors,
axles of miniature motors,
cameras, and DVD players
Standard coating with an emphasis on repelling water and oil The coating is soft (6B on a pencil hardness test)
Anti-adherent coating
Coating causing minimal refraction→Refractive index: 1.35 or lower (for film with a thickness of about 0.1 microns)
DS-1600 Coating with an emphasis on repelling water and oil
The coating is soft (6B on a pencil hardness test)
Better surface adhesion than DS-1100
Anti-adherent coating
DS-1900 -
