Use of Protectapeel

Why Protectapeel?

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

The protective maskants dry to form a skintight barrier, with excellent chemical resistance, that will protect surfaces during the etching process. The peelable maskant will retain its adhesion to the surface during etching, and can then be removed by hand peeling.

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

Peelable coating, peelable protective coatings and temporary protective peelable coatings are all manufactured by Spraylat International
