FLUOROCOAT Surface Modifier TECHNICAL DATA Product Code: TFCF SHEET PRODUCT DESCRIPTION FLUOROCOAT is designed to give high levels of liquid repellency to printed circuit boards and other electronic devices. The low film strength allows assemblies to be coated without masking. Any metal contacts, switches or other moving parts may be safely coated, as the coating is removed by very low friction forces. This eliminates the requirement for masking. FLUOROCOAT is a clear, mobile solution of an oleophobic- hydrophobic fluorochemical polymer in a hydrocarbon solvent. When applied to clean surfaces such as copper, glass, steel, aluminium or tin, the FLUOROCOAT solution dries to a thin transparent film of very low surface energy. The low energy film repels liquids such as lubricating oils, silicone fluids and water. FLUOROCOAT will form a clear, uniform film on a wide variety of substrates. TFCF contains a UV trace to allow easy inspection. BENEFITS Films cast from FLUOROCOAT solutions have excellent repellency to hydrocarbon oils, silicone oils, synthetic fluids and aqueous solutions. Copyright The dried film has a free surface energy which is lower than PTFE or Electrolube polyethylene. This property enables non-solubilising solvents such as 2003 All information is heptane, toluene and water to bead and drain freely from surfaces given in good coated with FLUOROCOAT leaving the film intact. The dried film can faith but without withstand temperatures above 100C for long periods without losing the warranty. repellent properly. Properties are given as a guide only and should USES not be taken as a specification. The low surface energy, insolubility and film-forming properties of Electrolube FLUOROCOAT make it an ideal coating for printed circuit boards to cannot be held give very high levels of moisture repellency. The thin film cast allows responsible for the performance coating under devices used in SMT. Complete finished boards can be of its products quickly and easily coated without having to mask edge connectors or within any piezo speaker devices etc. FLUOROCOAT can be used on almost application determined by the customer, who must satisfy themselves as to the suitability of the product.

METHODS OF APPLICATION The FLUOROCOAT solution can easily be applied to clean, dry surfaces by brush, spray or dipping. Dip coating is usually convenient and produces a more uniform film. Applying the coating by brush or spray may lead to incomplete and/or uneven films. FLUOROCOAT can be diluted with the hydrocarbon solvent to give an increase or decrease in the drying times. Normally the solution will air dry in one to two minutes. A slight increase in repellency and insolubility occurs if the film is baked at 100C for 15 minutes after drying.
