Super glues and adhesives made in the USA.
Adhesive - Bob Smith Industries, Insta-Cure Super Thin
Bob Smith Industries™ Insta-Cure™ Super Thin Cyanoacrylate. A must have for luthiers! Insta-Cure™ has a water-thin viscosity that wicks deep into joints by capillary action and cures in a matter of a few seconds (1-3 sec.). Surfaces to be bonded must be tight fitting (no visible gaps) and should be held together or clamped while you apply the CA around the edges of the seam. For glue applications with small gaps or looser fitting joints the higher viscosity Insta-Cure+™ is recommended.
  • Water-thin consistency
  • 1-3 second cure time
  • For tight fitting applications
  • Available in 1oz. and 2oz. sizes

WARNING: These products are eye and respiratory irritants. Product can bond skin instantly. Keep away from children!

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!

Adhesive - Bob Smith Industries, Maxi-Cure Extra Thick
Bob Smith Industries ™ Maxi Cure ™ Extra Thick Gap Filling Cyanoacrylate. A must have for luthiers! Maxi Cure ™ is the highest viscosity CA we have available and is great for extreme gap filling and finish fills. It can be carved with a knife or razor blade and sanded and feathered to form a finish which makes it great for chip repairs. The extra thick viscosity of Maxi Cure ™ also allows longer repositioning time than other glues (10-25 sec.) Apply Maxi Cure ™ in a coil pattern to one of the parts to be glued, spread glue evenly, then assemble parts. Hold or clamp firmly for 30-60 seconds. To speed up curing time use the Insta-Set accelerator! (S-F506)

Adhesive - Bob Smith Industries, Insta-Set Foam, Pump Spray
Bob Smith Industries INSTA-SET™ CA (super glue) Accelerator. INSTA-SET™ is a catalyst which acts as an accelerator that allows CAs to quickly cure in thick layers by enhancing the alkaline conditions during polymerization. INSTA-SET™ in a spray bottle is normally used to cure the CA that flows from joints when parts are pressed together. Applying an additional bead of thick CA along a seam and then curing it with INSTA-SET™ significantly enhances a joint’s strength. For difficult to bond materials, INSTA-SET™ can be applied to one surface and CA to the opposite surface. When brought together, they will bond instantly. INSTA-SET™ is formulated with a strawberry scent and activates CA in 6 to 8 seconds without any degrading of the CAs strength, which can occur with many other accelerators. It is compatible with all surfaces, even clear plastic and white foam.
  • Convenient pump spray (2oz.

Threadlocker - Bob Smith Industries, IC-LOC Blue
IC-LOC™ Blue is a medium thickness, medium strength thread lock that is applied to the threads of fasteners before assembly. Once the IC-LOC Blue™ is cured, the fasteners can be disassembled with standard hand tools if required. Uses
  • Threads of fasteners
  • Bolts
  • Screws
  • Nuts

Directions: Shake well, then apply IC-LOC™ Blue to the clean and dry threaded areas before assembling non-plastic parts. Product sets in 10 minutes, with full cure within 24 hours. IC-LOC™ Blue is anaerobic and cures in the absence of air, which occurs when a bolt, screw or nut is tightened. IC-LOC™ Blue prevents loosening of fasteners from normal use and vibration, but parts can still be disassembled with hand tools. IC-LOC™ Blue seals and prevents rusting of threads. Cured temperature range is -60° to +300°F (-51° to +149°C). Remove residue with a damp cloth. Similar to Loctite Blue.

Adhesive Softener - Bob Smith Industries, Un-Cure
Un-Cure™ debonder will soften cured CA. If parts are bonded incorrectly or your fingers are stuck together, a few drops of Un-Cure™ will dissolve the CA in about a minute. Apply on bonded skin and roll apart fingers. Once stuck, use acetone to clean off softened CA, then wash off with soap and water. Since cured CA is essentially acrylic plastic, anything that will dissolve CA will also soften most plastics. Care must be used, therefore, when using Un-Cure on plastics. Separating plastic parts with a razor saw is usually the best option. Works Well On:
  • Cyanoacrylates
  • Super Glues

Directions: Un-Cure™ will soften cured super glue (aka cyanoacrylate, CA). To release bonded skin (not near the eyes) apply Un-Cure™, then use a small, rounded object like a paperclip to separate the skin with a peeling action, applying more Un-Cure™ as needed until the skin areas are debonded. Wash the area with soap and water.

Adhesive - Bob Smith Industries, IC-GEL
IC-GEL™ is a cyanoacrylate paste that is extremely thick which comes in an applicator tube like toothpaste. It has the same bonding and curing time characteristics as Max-Cure™. IC-GEL™, however, can be applied to a vertical surface and will stay in place. It will not run. This can be very convenient for some assembly applications. Applying CA to the bottom of a horizontal surface, such as a ceiling, can be very difficult with anything other than a full standard CA bottle. IC-GEL™ can be applied at any angle with just a squeeze of the tube. The gel does, however, have a tendency to continue to come out of the tube for about a second after pressure is released, so this must be taken into account to apply the exact amount of IC-GEL™ that you want. IC-GEL™ is an excellent putty for plastic models. It will fill any void and can be formed to many shapes.

Epoxy - Bob Smith Industries, Quik-Cure
Quik-Cure™ 5 min. epoxy cures to a slightly flexible consistency. This lack of brittleness allows it to form a lasting bond in areas subjected to high vibration or stress. Quik-Cure™ shouldn’t be used in areas that are subject to long-term immersion in water; however, it works fine for the internal structure of wood framed boats. Quik-Cure™ is our only epoxy on which you can apply polyester resins. It can be mixed with microballoons to form a quick setting putty. Items bonded with Quik-Cure™ can be handled after 15 minutes. Full strength is reached in 1 hour. Works Best On:
  • Hard Wood
  • Glass & Metal

Works Well On:
  • Balsa Wood
  • Soft Wood
  • Fiberglass
  • Ceramics
  • Hard Plastics
  • White Foam
  • Reinforcing

Directions: Quik-Cure™ 5 min.

Threadlocker - Bob Smith Industries, IC-LOC Red
IC-LOC™ Red is a medium thickness, high strength thread lock that is applied to the threads of fasteners before assembly. Once the IC-LOC Red™ is cured, the fasteners are permanently together and cannot be disassembled. IC-LOC Red™ will maintain its strength up to 490° F. Uses
  • Threads of fasteners
  • Threads that need permanent bond

Directions: Shake well and then apply IC-LOC™ Red to the clean and dry threaded areas before assembling non- plastic parts. Product sets in 10 minutes, with full cure within 24 hours. IC-LOC™Red is anaerobic and cures in the absence of air, which occurs when a bolt, screw or nut is tightened. IC-LOC™ Red permanently prevents the loosening of threaded fasteners from shock and vibration, while sealing and preventing the rusting of threads. Cured temperature range is -60° to +300°F (-51° to +149°C).

Adhesive - Bob Smith Industries, Super-Gold+
Super-Gold+™ is foam-safe, odorless super glue. Super glues can produce fumes that can be irritating to the eyes and nose. While not toxic, some people can become sensitized to these fumes. Super-Gold+™ is BSI’s odorless form of Cyanoacrylate that gives the same high performance characteristics as BSI’s Insta-Cure+ without the irritating fumes. Super-Gold+ will not fog clear plastic and glass, which can occur with the use of standard Cyanoacrylates. It can also be used on all foams.
Starting at $16.95
Adhesive - Bob Smith Industries, Plastic-Cure
Plastic-Cure™ is a gap-filling formulation of CA that works best on plastics. It is packaged in a bottle with a brush built into its top, which in many cases is an easier way to apply the CA. As long as brush is put back into the bottle after use, the bristles of the brush will not harden. Care must be taken, however, not to introduce foreign material into the bottle. The brush should not be used, for example, to apply CA to wood that has been freshly sanded. Plastic-Cure will also bond wood, but its brush applicator at times will not be the best way to apply it. Plastic-Cure is superior for the application of false nails and wraps on fingernails, where its brush is the preferred method of application. Uses
  • Plastics
  • Wood
  • Foam
  • False nails and wraps on fingernails

Directions: Carefully unscrew the cap.

Adhesive - Bob Smith Industries, Insta-Flex+
Insta-Flex+™ clear rubber toughened has similar qualities to Bob Smith Industries black IC-2000™ but can be used in applications where you do not want the adhesive to be seen. The carbon component of IC-2000™ that gives the CA its black color also contributes to its unsurpassed strength. Since Insta-Flex+™ has this carbon removed, its strength is a little less than IC-2000™ but still superior to standard CA's. When esthetics are important and a flexible bond is required, Insta-Flex+™ is your best choice. It forms superior bonds to soft urethane and vinyl plastics. Both Insta-Flex+™ and Insta-Flex+™ work well when bonding R/C car tires.
