详细介绍

fc-742是透明的,低粘度的表面改性剂含氟聚合物涂层,是一种氢氟醚溶剂。

the solvent is non-flammable, has low toxicity and providesacceptable environmental properties for today's demandingelectronic applications. when applied to clean, moisture-freesurfaces such as copper, aluminium, ceramic, steel, tin or glass,certonal fc-742 dries to a thin transparent film with excellentanti-wetting, anti-stiction, anti-migration, and anti-corrosionproperties required in many diverse applications. certonal fc-742will form a clear, nearly invisible, uniform film that is insolublein solvents such as heptane, toluene and water. the polymercovalently bonds to glass and metal oxide layers. these films canendure up to 175°c for prolonged periods and maintain goodrepellency.  


the low surface energy films cast from certonal fc-742 haveexcellent repellency to hydrocarbon oils, silicone oils, syntheticfluids and aqueous solutions. with a surface energy of 11-12dynes/cm, certonal fc-742 films compare favourably to coatings ofpolyethylene and polytetrafluoroethylene, which have surface energyvalues of approximately 31 and 18 dynes/cm respectively. thisproperty enables non-solubilising solvents such as heptane, tolueneand water as well as liquids having low surface tension values suchas lubricating oils, silicones etc. to bead and drain freely fromsurfaces coated with certonal fc-742 while leaving the film intact.fc-742 coating exhibits many of the practical characteristicsdesired in a coating system, as seen below, making it especiallywell-suited for many applications.  

certonal fc-742 is an extremely stable surface modifierfluoropolymer rich in carbon-fluorine bonds. carbon-fluorine bondsgive the coating it's stable characteristics. the dry film is botholeophobic and hydrophobic. as the surface energy is so low, incomparison to coatings based on polyethylene and ptfe, manymaterials with low surface tension characteristics, such assilicone oils and lubricating oils, bead and drain freely from acertonal fc-742 coated surface. the low surface energy of thecoating also helps to prevent solid materials adhering to thesurface.
