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.

service related FAQ’s

Can i apply Protectapeel myself, or do I need a professional?2026-04-08T11:57:46+00:00

Protectapeel is designed for straightforward application, making it easy for you and your team to apply it independently. To help you achieve the best results, we also offer complimentary training with our application technician.

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

Once the windows are installed, apply Protectapeel immediately to protect them during finishing works.

Does Protectapeel require any special equipment to apply?2026-04-08T11:53:53+00:00

Protectapeel is applied using an airless spray gun. For optimal results, we recommend using the Graco 390. If needed, spray guns are also available for rent directly from us.

Can Protectapeel be used in harsh weather conditions?2026-04-08T12:07:08+00:00

Yes, Protectapeel is specifically designed to endure harsh weather conditions, including UV rays, rain, and wind, making it ideal for outdoor use. Additionally, Protectapeel Anti-Rust has undergone 1,440 hours of salt spray testing and achieved a C5 High durability rating in compliance with EN ISO 12944-6 and EN ISO 9227 standards.

Can other surfaces be protected during construction?2026-04-08T12:30:05+00:00

Yes, Protectapeel can be applied to a range of non-porous surfaces, including flooring, sanitary basins, countertops, windows, frames, and doors. Before project handover, it can be easily removed by hand peeling, revealing clean, undamaged surfaces without delays or additional costs. 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.
