Chemical Milling and Etching Maskants

Protectapeel’s chemical etching maskants are applied to metal. The peelable coating is a acid resistant.


Spraylat’s spray on protective coating will protect metal from acid corrosion. Protectapeel’s peelable coating is ideal for chemical milling


Spraylat’s spray on peelable protective coating, Protectapeel, is easily removed from metal after etching

Why Protectapeel?

Spraylat Protectapeel Hydromask is 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 skin-tight 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 yet can be removed by hand peeling.

Spraylat 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.
