GORE® TETRA-ETCH® Fluorocarbon Etchant

GORE® TETRA-ETCH® Fluorocarbon Etchant

GORE® TETRA-ETCH® fluorocarbon etchant, which will not ignite when exposed to moisture, is a chemical solution for treating the surface of fluorocarbons to make it markable, bondable and potable. 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.


Wherever there is a use of fluorocarbons, there is a use for GORE® TETRA-ETCH® etchant; from wire and cables products to fluorocarbon sheet and tape, from chemical tank liners to printed circuit boards, from engineering components to electronic potting.
