Most Tangent masking materials for acid stripping, plating, and anodizing are removable by peeling. Removal can be accomplished at room temperature, but the peeling process can be accelerated by incorporating a hot water dip/rinse prior to peel. Elevating the temperature of the peelable masks causes them to become more elastic and easier to remove.
For ultimate protection, Tangent has created a selection of super-high adhesion plating/anodizing masks. The most practical removal method for these masks is incineration. This limits their use to components made from nickel alloys (super alloys), and any other materials that can withstand high temperature processes. Suitable applications include processing landing gear, turbine blades, vanes, stators, nozzles, and transitions. Tangent high adhesion masks also provide protection during machining operations, including milling and grinding. The mask and component can be machined as one, assuring maximum surface protection.
Once the processing is completed, the masking materials can be burned-off at temperatures in the range of 900°F to 1200°F. Quite often, the incineration process can be combined with an existing heat treating operation for maximum process efficiency. Component surfaces are residue-free after mask removal, and ready for the next operation.
Multiple viscosities of each mask are available to accommodate various dispense methods which can include dip, spray, or hand application. The masks are offered with a color additive to provide surface contrast for better visibility of coverage during dispensing and removal.

UV curable masking products are easily applied and cured in seconds with a UV light source. A single application provides consistent protection from blasting, hot acids, alkali solutions, plating, etc. Masking materials in multiple viscosities to accommodate a wide variety of applications. Removal ranges from simple peel to incineration or heat treating for applications with more severe surface protection requirements.read more
Orthopedic prostheses such as hip joints, knees, bone plates, and spinal implants contain both highly polished surfaces and rough, coated surfaces. Tangent UV light curable masking materials can provide absolute protection and delineation between these surfaces. Tangent UV masks are designed for removal by manual peel, which can be accelerated by incorporating a quick hot water dip/rinse prior to peel.read more
