TETRA-ETCH fluorocarbon etchant is a non-pyrophoric chemical solution for treating the surface of fluorocarbons to make them markable, bondable and pottable.
UN Number: UN2924 CL3 II
Limited Quantity: 5L
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-ETCHÂ® etchant reacts with the surface molecules of a halogenated polymer to form a carbonaceous film of free radicals.
These radicals react with O2 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.
