TFCF – Fluorinated Polymer Varnish

TFCF is a unique fluorinated polymer varnish formulated to provide high levels of liquid repellency for PCBs and other electronic devices. Once dry, TFCF forms a thin transparent film with very low surface energy. The film strength allows varnishing without masking. As TFCF is mechanically weak and is easily removed by minimal friction, the requirement for masking components, such as switches, piezoelectric speaker devices and contacts prior to varnishing, is not necessary.

Key Properties:

• Thin “film” coating with excellent moisture resistance
• Assemblies can be coated without masking
• Varnish is removed by light mechanical wear, ideal for connectors
• Contains UV traces for easy inspection
