Leather Bond-3D

Leather Bond-3D by Leather Doctor is a water-based medium soft polyurethane bond for leather tears, rips, abrasions, cat scratches, and filling repairs.

Bond-3D will not lift or damage the leather finishes, unlike other dry solvent-based glue.

Bond-3D works in conjunction with leather Patch-4S as sub-patch and suede fibers as fillers.

Bond-3D is to be tested for darkening effect satisfaction on an inconspicuous or hidden spot before actual application.
