Developed for filling cracks and small voids and stabilizing knots in very dark woods, this cyanoacrylate glue dries in seconds to an opaque jet black to effectively disguise the repair in the surrounding wood. Alternatively, it is an excellent way to highlight imperfections to create distinctive accents in reclaimed, spalted or burl wood. It also works well for inlay work such as lettering and for bonding dark-colored materials.
With a medium-thick viscosity (500 cPs) similar to the consistency of syrup, it penetrates voids up to 0.008" wide and bonds in 40 to 60 seconds. Curing time is longer when filling voids than when the glue is used as an adhesive due to the increased volume of glue applied to a void. For filling voids, building layers of glue alternating with accelerator is recommended to ensure full curing.
The glue comes with two applicator caps, a clog-resistant stopper, and eight precision microtips that fit over the dispensing nozzle to permit extremely accurate glue application. The microtips can be cut to a desired opening width and are good for more than one application if soaked in acetone immediately after use.
