## Overview

Bob Smith Industries BSI-109 Insta-Cure Gap Filling is a high-viscosity cyanoacrylate adhesive designed to bridge gaps in loose-fitting joints. With a rapid 15-second full cure time, it delivers professional-grade bonding for metal, wood, and glass surfaces. Packaged in an 8 oz bottle and proudly made in the USA, this glue is favored by professionals nationwide for durable, precise repairs.

## Description

Insta-cure+ is a higher viscosity ca for loose fitting joints in which the adhesive must bridge gaps. 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, do not 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 out.

Review: Great Glue - I've been using BSI glues for years. Both as glue and as coating for my turned wood pens. Works great every time. If you use the accelerator with these glues they may become brittle and the glue joint could break easily. For a good long lasting joint, don't use the accelerator.
Review: Super expensive for glue, but the best - I want to start out saying this is the glue my company nation wide uses, it's top line stuff. I bought it for use outside of work and learned how expensive it is, but I suppose the best will be expensive. Warning to those who decide to buy some though, this stuff has a super strong chemical fume and can burn your nose, throat and eye balls. So just be cautious on how much you use at once. If you need to use a lot, at least wear a respirator mask. This stuff dries quickly to. If it gets on your skin it can burn a little. Oddly enough if you use paper towels to wipe it the paper towel will smoke. It's interesting. Adheres to metal, wood and glass very well! Great product for professionals!
