Chemical Milling, Etching & Pickling

Protectapeel Etchprotect 284/6 chemical milling maskant is 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 chemical milling maskant 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 straight-forward 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.
