(Wet) Acid Stripping, Plating, and Anodizing Masks
Tangent Industries’ temporary UV masking materials for acid stripping, plating, and anodizing are formulated to resist prolonged immersion in heated solutions of acids, degreasers, chemical stripping agents, and plating baths. These masks provide dependable, edge-to-edge surface protection, minimizing rework and scrap costs.
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.
