Temperature-resistant plugs from
Caplugs/Nigara Masks & Plugs.
From die cuts and liquid maskants to caps, plugs, tapes and discs, today's suppliers offer a variety of masking products to help finishing professionals save time and achieve a high-quality finish.
Masking is an essential part of any finishing process; however, it can also be a time-consuming, labor-intensive endeavor. Aware of the many challenges faced by today's finishing professionals, masking suppliers have become essential partners in finding new solutions that can save time and money, and achieve a precise, high-quality finish. Following is a roundup of some of these solutions.
Die Cuts
Argon Masking Corp.This company specializes in tapes and masking products for powder coating, plating and anodizing operations. An in-house die-cutting plant can cut most tapes into any shape (even wording and numbers) for easy masking. The horse pictured here was cut out of its PC400 green powder coat tape. Die cuts are designed to save time and money - the user simply peels them off the backing, places them on the substrate and paints. The company also manufactures silicone and EPDM caps, plugs, pull plugs and metal hooks. Call 626.357.8743 or visitargonmasking.com
High-Temperature Masking
Caplugs/Niagara Caps & PlugsThese companies have developed a temperature-resistant material specifically for the finishing industry. Flex500Plus is designed to withstand service temperatures beyond 500°F and is suited for powder coating, plating, painting, anodizing, chemical processing and other applications. The companies supply thousands of masking parts in a range of sizes, styles and colors. Most of the parts are available in several different materials including silicone, vinyl, paper and polyester.

Interior Part Masking
Echo Engineering & Production Supplies, Inc.Designed to mask the interior of a part tunnel and multi-level countersink holes, the Mating Plug is made from a combination of metal and rubber and can withstand high-temperature finishing processes, such as powder coating, plating and e-coating. The ability to screw the flanged plug to its mate creates the airtight seal necessary for e-coating applications. Designed to be user friendly, the plug features turn tabs on the plug ends that allow for easy application and removal. The lip on the rim of the plug guarantees that the multi-level counter sink holes are also protected. Call 888.324.6365 or visitwww.echosupply.com
Masking Products
EPSIThis company's standard masking product range includes masking caps, plugs, stoppers, die cuts, tapes, tubing and sheeting, and hooks. Its patented Wishbone masking discs feature a center pull-tab design that allows users to easily find and remove discs obscured by painting or powder coating. The Wishbone system also prevents the need for costly rework of coated surfaces marred during disc removal. The design creates a pop-up center tab that is reportedly easier to apply than standard discs, and that remains visible and easy to grasp even after thick paint or coating applications to provide a savings in time and labor costs. The company's F12 tape has a 4.5 mil electrical grade glass cloth backing for easy placement and removal and is coated with 2.5 mils of silicone adhesive. This adhesive system is a crosslinked, semi-cured blend of silicone that will withstand 500°F for up to 45 minutes. The company also specializes in rubber molding for OEMs. Call 262.253.EPSI (3774) or 866.ASK.EPSI, or visitwww.epsi.com
Custom Masking
Hi-Tech Flexible Products, Inc.This company has created thousands of custom masks for wet spray, powder coat, e-coat and plating. The products are designed to be easily applied and removed so that finishing professionals can ergonomically mask in seconds. The masks are made from fully cured Dow Corning silicone, so there is no migration to affect painting operations. Because paint will not adhere to silicone, the masks can be cleaned of paint buildup and used repeatedly. The masks can also take a very high baking temperature (up to 600°F) and can be left on the part through the oven. Call 517.783.5911 or visitwww.htfp.com
Masking/Hanging Solutions
Magic Rack®/Production Plus Corp.Parts to be painted can often be masked by using the same hook used to hang the part. This company has used this idea for years and has developed hundreds of hooks designed to give finishing professionals line density, part control and masking, all at the same time. The hooks can be cleaned and reused multiple times to help companies save money and solve paint line problems. Call 614.492.8811 or visitwww.MagicRack.com
Magnetic Masking
Magnum Magnetics Corp.The Magnum Masking Magnet™ is a flexible magnetic maskant that will adhere in wash systems and can be die-cut to specifications. It can provide an economical alternative for high volume and repeat masking applications. Call 800.258.0991 or 740.373.7770, or visitwww.magnummagnetics.com
