Protectapeel Hydromask is a range of maskants used in the chemical milling or chemical etching process. The coatings are suitable for use in several etchants including hydrofluoric/hydrochloric acid or sodium hydroxide, also known as caustic soda.

The maskants dry to form a skin-tight barrier, with excellent chemical resistance, that will protect surfaces during the etching process. The maskant will retain its adhesion to the surface during etching yet can be removed by hand peeling.

Protectapeel Hydromask has excellent etch properties which will allow users to cut by hand or laser. The coatings will prevent “etch creep” at the cut edge and are ideal for small or large-scale etching.

Easy to scribe

Protectapeel maskants can easily be cut by hand or laser to ensure the precise shape you desire. It is simply hand peeled when required.
