Plating process or bonding process  require a specific treatment  for materials with PTFE (Teflon ® ) *
It is necessary of making adherent an anti adhesive material. These materials meets more particularly in the ultra high frequencies applications (microwaves substrats).

NTS developed a process for the chemical preparation of PTFE: Sodium microetch




Treatment of PTFE  fluoropolymer resins

The NTS 570 allows preparing surfaces and the holes on the fluoropolymer materials.

Its specific viscosity allows it to treat small diameter holes.

Sodium microetch NTS 570 prepares surfaces before metallization, bonding or before lamination.

The stability of the solution makes it possible to treat surfaces more significant than the other products of the market, in that it has a real economic advantage
