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.
