CERTONAL FC-742

The solvent is non-flammable, has low toxicity and provides acceptable environmental properties for today's demanding electronic applications. 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.

Certonal FC-742 is an extremely stable surface modifier fluoropolymer rich in carbon-fluorine bonds. Carbon-fluorine bonds give the coating it's stable characteristics. The dry film is both oleophobic and hydrophobic. As the surface energy is so low, in comparison to coatings based on polyethylene and PTFE, many materials with low surface tension characteristics, such as silicone oils and lubricating oils, bead and drain freely from a Certonal FC-742 coated surface. The low surface energy of the coating also helps to prevent solid materials adhering to the surface.

Certonal FC-742 can be used as an anti-migration barrier to prevent lubricant materials migrating from critical wear components in gyroscopes, precision bearings, MEMS spindles and similar mechanical, critical wear devices.

The application of Certonal FC-742 should be carried out in a controlled manner to maintain careful management of the solids content. Acota provide a range of equipment designed for controlled application of Certonal FC-742. The equipment applies the material by dip application, which maintains consistent solids content, thus ensuring uniform dry film application. Acota systems are designed to ensure that the coated products emerge dry from the system and all solvent is recovered which in turn helps to maintain a consistent solids content.
