UV Resin Masks for Metal Finishings

Metal finishing operations often incorporate removable protective barriers or temporary masks to protect component surfaces and cavities during processing. For years, temperature resistant tapes, waxes, and solvent or water- based coatings were the only protective masks available for processes such as grit blasting, shot peening, acid stripping, and plating. Applying these masks is very labor intensive and can be a lengthy process. Performance is not always consistent with traditional masks, which can lead to substantial losses resulting from rework and scrap.

An alternative to traditional masking materials and methods is now available from Panacol-USA. Highly resilient materials incorporating light curable technology are offered for the specific purpose of temporary surface protection. These uv resin masks can be easily dispensed on surfaces and into cavities by manual methods or with automated dispensing systems. Once dispensed, the liquid uv resin mask is cured (hardened) in seconds using a UV light source. This dramatically reduces labor time, and allows masking to be incorporated as an in-line process for continuous production flow.

Once the processing is completed, the uv resin masks can be removed by peeling or incineration, (900°F to 1200°F). Quite often, the incineration process can be combined with an existing component heat treating operation for maximum process efficiency. Component surfaces are residue-free after the masks are removed, and ready for the next operation.

Panacol-USA uv resin masks are formulated to primarily address the challenges of three unique applications: (dry) media blasting, (wet) plating/anodizing, and orthopedic prostheses processing. However, these uv light masks can also be used in many other applications and processes. They can mask surfaces from aggressive paints and coatings, or provide surface protection during shipping and handling, machining operations and grinding. As an added benefit, uv resin masks can extend the life of fixtures used to secure components during machining, blasting, peening, and plating operations.

Also available is a water soluble mask for components with intricate geometries. This UV curable mask will dissolve when placed in a slightly acidic water bath.
