Cyanoacrylates (CAs) have become the adhesive of choice for most hobby and household applications. High quality CAs such as INSTA-CURE™, when used properly, form bonds that in many cases are stronger than the material that is being adhered. INSTA-CURE™ is a highly refined CA which, combined with its freshness, gives a guaranteed 2 year shelf life. CAs are reactive monomers that chemically link (polymerize) when pressed into a thin film. The very thin layer of water moisture present on most surfaces acts as an alkali, or weak base, which is the catalyst that results in bonding; however, the presence of detectable amounts of water usually degrades the performance of CAs.

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.

INSTA-CURE™ has a water-thin viscosity that wicks deep into joints by capillary action and cures in a matter of a few seconds. Surfaces to be bonded must be tight fitting and should be held together while you apply the CA around the edges of the seam. At the moment CAs cure, they give off a vapor that can irritate the nose and eyes, so be prepared. Thin CAs work very well on balsa since they penetrate into the wood and form more than just a surface bond.

Insta-Cure plus - thick cyanoacrylate adhesive - hobby glue -  BSI

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, 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.

Maxi-Cure - extra thick cyanoacrylate adhesive - hobby glue for plastics - BSI

MAXI-CURE™ extra thick CA is the best CA for most plastics, including GE’s Lexan MAXI-CURE™ is the best choice for plastic model assembly. When used with INSTA-SET™, it works better than any putty for modifying or filling voids. It can be carved with a knife or razor blade and sanded and feathered to form a finish indistinguishable from plastic.

MAXI-CURE™ bonds fiberglass, hardwood, metal and rubber better than any other hobby adhesive. For gluing to the inside, clothtextured surface of fiberglass, scrape the area to be bonded with a razor blade or coarse sandpaper before using MAXI-CURE™ or any other adhesive. It also is best for bonding the tires for R/C cars.


IC-2000 - rubber toughened cyanoacrylate adhesive - hobby glue for fiberglass - BSI

IC-2000™ is a rubber-toughened cyanoacrylate that forms superior shock resistant bonds on non-porous surfaces. The black colored CA has added flexibility for the bonding of metals, fiberglass, rubber, carbon-fiber and other advanced materials. For model use, IC-2000™ is ideal for the bonding of bulkheads, formers and servo rails to the inside of fiberglass hulls and fuselages. Setup time is 20-40 seconds, which can be accelerated with INSTA-SET™. When cured, IC-2000™ is pliable enough to be carved with a hobby knife. IC-2000™ is the best adhesive for R/C car tires.


IC-Gel - extremely thick cyanoacrylate adhesive - putty for plastic models - BSI

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 MAXI-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. Applying INSTA-SET™ allows IC-GEL™ to be sanded or filed to final shape in less than 20 seconds. Autobody repairmen have finished their jobs in a fraction of the time by using IC-GEL™ with the additional advantage over normal body putties of superior bonding to metal surfaces.

IC-GEL's™ most popular application is for the bonding of fragments of live coral (frags) to underwater rocks in aquariums. It has proven to be non-toxic to aquatic organisms and provides instant bonding for the propagation of the coral. IC-Gel has a superior shelf life of over three years and its application nozzle makes it the easiest of all CAs to apply.


Insta-Flex - flexible thin cyanoacrylate adhesive - hobby glue for CA hinges - BSI

INSTA-FLEX™ flexible thin CA is ideal for many applications, including the installation of CA hinges. When cured, INSTA-FLEX™ does not turn brittle and remains clear, even if accelerated with INSTA-SET™. It has superior shock resistance. Although not as thin in consistency as INSTA-CURE™, INSTA-FLEX™ still has good penetrating qualities and its application can be easier to control. For CA hinges, we recommend drilling a 1/16" hole in the center of the hinge slots to insure the complete saturation of the hinge when INSTA-FLEX™ is applied. INSTA-FLEX™ has a different, less irritating odor compared to regular CA's, but still can not be used on white foam. INSTA-FLEX™ has also proven to be superior when bonding anodized aluminum.

Insta-Flex plus - clear rubber toughened cyanoacrylate adhesive - soft urethane adhesive - BSI

INSTA-FLEX+™ clear rubber toughened has similar qualities to our 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. When a joint has a larger than normal gap, flexible CA's provide superior shock resistent bonds.

 

Pocket CA - cyanoacrylate adhesive - new improved top - hobby glue - BSI


BSI's Pocket CA

BSI has added a 4 oz. size to go along with our 3/4 oz. cyanoacrylates. These Pocket CAs feature a new top that has a pin built into the cap that covers the nozzle. This pin seals the bottle so that if it is tipped over, the bottle will not leak. This makes the Pocket CAs ideal for keeping in your tool or field box, just like our IC-Gel. One disadvantage that the new Pocket CA top has is the bluntness of the nozzle. This makes it more difficult to apply small amounts of the CA, especially in tight places. From the feedback we have received, it appears about 25-30% of users prefer the new Pocket CA top, which means that over 70% prefer our standard top for general bonding purposes. Most users are buying both types. Our original top for the workshop, and the Pocket CA for use out in the field. The 3/4 oz. Pocket CAs are available in BSI's Insta-Cure, Insta-Cure+, Maxi-Cure and Super-Gold+. BSI's new extender tip #304 works on the Pocket CA.
