Certonal FC732 Electronic

When applied to clean, moisture-free surfaces such as copper, aluminium, ceramic, steel, tin or glass, Certonal FC-742 dries to a thin transparent film with excellent anti-wetting, anti-stiction, anti-migration, and anti-corrosion properties required in many diverse applications. Certonal FC-742 will form a clear, nearly invisible, uniform film that is insoluble in solvents such as heptane, toluene and water. The polymer covalently bonds to glass and metal oxide layers. These films can endure up to 175°C for prolonged periods and maintain good repellency. 

The low surface energy films cast from Certonal FC-742 have excellent repellency to hydrocarbon oils, silicone oils, synthetic fluids and aqueous solutions. With a surface energy of 11-12 dynes/cm, Certonal FC-742 films compare favourably to coatings of polyethylene and polytetrafluoroethylene, which have surface energy values of approximately 31 and 18 dynes/cm respectively. This property enables non-solubilising solvents such as heptane, toluene and water as well as liquids having low surface tension values such as lubricating oils, silicones etc. to bead and drain freely from surfaces coated with Certonal FC-742 while leaving the film intact. FC-742 coating exhibits many of the practical characteristics desired in a coating system, as seen below, making it especially well-suited for many applications.
