Joint Shield
[LE-277]

When you need more than one Mag-Stop Plate to cover an area, how do you handle the joints? Joint-Shield is the perfect solution! This is a generous .010" thick, fully hydrogen annealed magnetic shielding alloy with adhesive backing (rated 0 - 200?F) on one side. Simply butt the Mag-Stop plates tightly together, and "tape" over the seam with Joint-Shield high permeabilty alloy. This method offers much less bulk and better appearance than the old overlap technique and provides excellent shielding integrity. Simple to use: just cut to desired length with a heavy scissors, peel the protective backing and press into place!

Joint-Shield can also be used by itself as an excellent magnetic shielding material when a 4" width and adhesive backing is desirable (wrap it around wiring and conduit, speaker magnets, even small appliances like shavers and hair dryers!). Joint-Shield can be shaped by hand, without the need for special tools, but watch the sharp edges.

General Information:
Pressure sensitive adhesive (peel and stick) on one side of the material permits quick and easy prototype and shield fabrication by hand. The material exhibits an aesthetically clean and bright metallic surface. The annealing process leaves the alloy "dead soft" so it should be protected from denting and scratches. Bending is possible, but gently rounded bends are favorable to sharp creases and acute angles. Great care should be taken to avoid heating this material above 400?C since heating will affect the grain size and deteriorate shielding properties. Unfinished edges may be sharp so care should be taken during handling, and proper finishing of edges is required to protect end user.

Maintenance:
Because of its high nickel content, this alloy is highly corrosion resistant. Cleaning is simple with a soft cloth, or you can use mild soapy water (be sure to rinse well and dry). If required for cosmetic purposes, this material can be spray painted or adhesive veneers may be applied.
