Chemical Milling

Spraylat Protectapeel's protective coatings are the most effective solution to ensuring accurate chemical etching of metals. The coating is acid resistant and will prevent areas being corroded when dipped.


How does Spraylat Protectapeel's chemical etching solutions work?

Chemical Milling Maskants
  • Liquid applied – spray, dip or roller

  • Water-based chemical milling maskant

  • Easy application and removal - hand peelable

  • Excellent chemical resistance

  • Easy to scribe by hand or laser cut

  • No loss of adhesion

  • Air, Microwave or Oven dried.

  • Environmentally Friendly

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.

Easy to scribe

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