Adhesive - Bob Smith Industries, Insta-Cure Gap Filling

Bob Smith Industries™ Insta-Cure+™ Medium Gap Filling Cyanoacrylate. A must have for luthiers!
Insta-Cure+™ is a higher viscosity CA for loose fitting joints in which the adhesive must bridge gaps or the parts to be glued don’t fit perfectly. Medium viscosity super glue is the most common glue used in many luthiery applications due to it’s cure time and viscosity. Recommended for binding repair and small poly finish touch ups.
Normally, the thicker CA is applied to one surface and then the parts are held tightly together for about 5 to 15 seconds. For large surface areas, including those with close fitting joints such as laminations, INSTA-CURE+ ™ should also be used. To prevent premature curing, don’t spread the glue into a thin film. Lay down a serpentine bead with about 1" separations on one surface, then assemble the parts, letting the pressure spread the CA out.
To speed up curing time use the Insta-Set accelerator! (S-F506)
- Medium, gap filling consistency
