Chemical Milling, Etching & Pickling

Protectapeel Etchprotect 284/6 is a temporary peelable maskant designed for  use during chemical milling, etching and pickling processes.  Used and trusted worldwide since 1992, we have supplied maskants to companies such as Standex, Mold Tech, GKN and  BAE. 

Formulated to withstand aggressive chemical environments,  Protectapeel provides a durable barrier that protects  selected areas of metal components during material removal  processes. This ensures precise etching while maintaining  clean, defined edges and protecting critical surfaces from  unwanted exposure. The coating adheres strongly to a wide  range of metal substrates, including aluminium, stainless  steel and specialist alloys commonly used in aerospace,  engineering and precision manufacturing. 

Protectapeel can be easily applied by spray, brush or roller  to suit different production environments and component  geometries. Once cured, the coating forms a flexible, uniform  film that resists the chemicals used in milling and etching  operations while remaining simple to remove by hand when  the process is complete. The peelable nature of the product  eliminates the need for harsh stripping methods and helps  maintain the integrity of the underlying surface. 

By providing reliable masking performance and  straightforward removal, Protectapeel helps manufacturers  improve process efficiency, reduce preparation time and  minimise costly rework. Its versatility and proven performance  make it a trusted solution for protecting critical components  during precision chemical processing.

How to cover countertops during construction?2026-04-08T12:28:40+00:00

Protectapeel offers a simple solution for protecting countertops during construction. It can be applied directly without the need for measuring, cutting, or taping. Simply spray it on, allow it to dry, and it will shield countertops from damage such as scratches, mortar, and paint overspray. Before application, you must always apply the Protectapeel product to a small test area to test the substrate’s suitability. You must ensure that all substrates are well covered. Allow the product to dry for 48 hours, and then check that the Protectapeel product will peel away from each substrate.

How long does Protectapeel last for?2026-04-08T12:11:00+00:00

Protectapeel is suitable for use up to 12 months.

When should you protect windows during construction?2026-04-08T12:25:06+00:00

Can door and window frames be protected during construction?2026-04-08T12:23:50+00:00

Yes, Protectapeel can be applied to non-porous door and window frames to protect from damage caused by scratching, plaster, or weather exposure. Before full application, you must always apply the Protectapeel product to a small test area to test the substrate’s suitability. You must ensure that all substrates are well covered. Allow the product to dry for 48 hours, and then check that the Protectapeel product will peel away from each substrate.

How do you protect glass during construction?2026-04-08T12:22:53+00:00

Protectapeel provides a peelable coating that protects glass from scratches, dirt, and damage during construction. It is easily applied using an airless spray gun, reducing labour requirements on-site. Once the project is complete, the coating can be effortlessly peeled away, leaving the glass clean and undamaged.
