TETRA-ETCH® fluorocarbon etchant is a non-pyrophoric chemical solution for treating the surface of fluorocarbons to make them markable, bondable and pottable. A sodium compound in the solution reacts with highly fluorinated polymers to form a reactive film on the polymer surface. Nearly any adhesive can be used on this treated surface.

The active sodium in TETRA-ETCH® etchant reacts with the surface molecules of a halogenated polymer to form a carb?onaceous film of free radicals. These radicals react with 02 and H2O and each other to form a layer of chemically active groups attached to the surface. These then react with adhesives and potting compounds to form a true chemical bond.
