Product is considered by the dentists and orthodontists to be the best Polish etching gel, winner of many awards and prizes on different exhibitions and dental fairs. Composition: o-phosphoric acid 36%, gel base, dyestuff Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete.

Wright Etchant reveals crystal dislocations, stacking faults, swirls, striations and slip lines. The etchant is applicable to (100) and (111) crystal orientations, for both p and n type crystals over a wide range of resistivities.
