Chemical Milling 


World First For Maskants

Protectapeel is a water-based protective coating that is applied by airless spray or roller and dries to form a strong, durable coating that can protect internally or externally for up to 12 months. Protectapeel is used amongst a number of sectors for surface protection against damage such as; flash rusting, abrasion, weld spatter, salt water, acid rain and weathering. 

However, more recently Protectapeel is rapidly being used within the aerospace sector for surface protection during the chemical milling process on aircraft fuselage and fan blades. 

Spraylat International Ltd is the first company in the world to introduce a full range of water-based maskants for chemical milling. The maskants are capable of working in all known etchants including; hydrofluoric, hydrochloric acid and sodium hydroxide.

The range of water-based maskants has been introduced to cope with the growing demand for environmentally friendly products. In addition, the products offer excellent etching qualities. Spraylat International Ltd Managing Director, Andrew Keir added; “the results from the extensive pilot trials have been very encouraging with a number of users reporting good results, process efficiencies and costs savings.”
