Treatment of Diverter
Strips on Aircraft
Radomes
If static diverters are present on the radome, either segmented or solid diverters, you must
not cover them with the 3M™ Polyurethane Protective Boot. Apply the Polyurethane
Protective Boot as described on pages 3 & 4, carefully trim the material of the Polyurethane
Protective Boot from the edge of the diverter strip using a small scissors. Take extreme
caution not to score or cut or otherwise damage the paint on the radome. When this
trimming operation is complete, finish by neatly applying 3M™ Scotch-Weld™ Epoxy
Adhesive DP-190 to seal the edges of the Polyurethane Protective Boot to the radome
around the cutout for the diverter. Masking tape works well to insure a neat application of
the edge sealant.
