TFCF Fluorocoat Surface Modifier

In Stock

TFCF is a unique, fluorinated polymer coating formulated to provide high levels of liquid repellence to printed circuit boards and other electronic devices. Once dried, TFCF forms a thin transparent film of very low surface energy repelling hydrocarbon and silicone oils, synthetic oils and aqueous solutions. The low film strength allows assemblies to be coated without masking. As TFCF is mechanically weak, it is easily removed by minimal friction, therefore eliminating the requirement for masking components such as switches, piezo speaker devices and contacts prior to coating. TFCF can be sprayed, dipped or brushed, but it is not necessary to dilute TFCF before application. TFCF contains a UV trace to aid inspection and ensure an even coat has been applied.
