Each of the bottle sizes are sold individually not as sets. Bob Smith Industries Insta-Cure ™ Super Thin Glue 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. Bob Smith Industries Insta-Cure+™ Medium Gap Filling Glue 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. Bob Smith Industries 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.SUPER-GOLD™ and SUPER-GOLD+™ are our ODORLESS INSTA-CURE CAs They are non-frosting and take only 2 or 3 seconds longer to bond. There are no fumes that irritate the nose and eyes. The SUPER-GOLD™’s do not attack white foam; therefore, they can be used in the building of foam core wings and the assembly and repair of plastic and foam ARF’s. They will not fog clear plastic. SUPER-GOLD+™ is ideal for attaching clear canopies in plastic model kits; however, MAXI-CURE™ is still recommended for assembling the rest of plastic kits. Wood can be bonded to white foam with SUPER-GOLD +™ in less than fifteen seconds. For bonding foam to foam, spray a very light fog of INSTA-SET™ to one piece and apply SUPER-GOLD+™ to the other before joining. Excess INSTA-SET™ may create too much heat, which can melt the foam. Both SUPER-GOLD™’s cure to a more flexible consistency for better shock absorbtion. Whenever a large amount of CA is to be used in such applications as saturating fiberglass or Kevlar, SUPER-GOLD™ eliminates the irritating fumes from the evaporating monomer that make repeated use of CA unpleasant at times. MAXI-CURE™ has proven to be very popular in the archery business for the fletching of vanes onto aluminum and carbon arrow shafts. Along with being the strongest, MAXI-CURE™ is usually the least expensive option for this application.Bob Smith Industries Insta-Flex Product Description (BSI119): Bob Smith Industries INSTA-FLEX™ flexible thin cyanoacrylate is ideal for many applications, including the installation of cyanoacrylate 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 cyanoacrylate 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. Bob Smith Industries INSTA-FLEX™ has a different, less irritating odor compared to regular cyanoacrylates, but still can not be used on white foam. Bob Smith Industries INSTA-FLEX™ has also proven to be superior when bonding anodized aluminum. Bob Smith Industries Insta-Flex Product Description (BSI120): 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.Extra CA Top - #312 Replacement top that is on all of BSI's non-Pocket CAs That means only is good for 1/2 oz & 1 oz. & 2oz.
