UV Masks for Acid Strip, Plating, and Anodizing

Panacol’s 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 Panacol-USA 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. Hot air may also be used if practical for the application. Elevating the temperature of the peelable masks causes them to become more elastic and easier to remove.

For maximum protection, Panacol-USA has created a selection of super-high adhesion plating masks. The most practical removal method for these masks is incineration. This limits their use to components made from nickel alloys (super alloys), and other metals that can withstand high temperature exposure.  Suitable applications include the processing of landing gear, turbine blades, vanes, stators, nozzles, and transitions. 

Once the acid stripping or plating 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 incineration, 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 from syringes. The masks are available with a color additive to provide improved surface contrast for better visibility of coverage during dispensing and removal.

Please view the masking materials listed below for a possible candidate for your application. Contact Panacol-USA to confirm your product selection and to secure additional application assistance.  This may include requesting samples and UV curing recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Panacol-USA will investigate other solutions which can include developing custom masking material specifically tailored to the complexity of your application.

Specially formulated adhesives from Panacol-USA are resistant to aggressive chemicals, making them the perfect solution for acid stripping.
