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. QUIKCURE™ 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.



MID-CURE™ 15 min. epoxy is used in larger areas where more working time is needed. It is more water resistant and can be used as a substitute for QUIK-CURE™ in most applications. MID-CURE™ is our most flexible epoxy and is ideal for gluing to fiberglass surfaces. Allow 45 minutes before handling parts and 2 hours for full strength.



SLOW-CURE™ 30 min. epoxy works best for forming reinforcing fillets on joints. It has the highest strength of our epoxies. It is waterproof and more heat resistant. SLOW-CURE™ can be used for bonding if you’re willing to wait overnight. Fillers such as microballoons can be mixed with SLOW-CURE™ and FINISH-CURE™ to form a putty-like consistency. Such fillers will usually decrease the working time by about 25%. Bonded objects can be handled after 8 hours and the cured epoxy reaches full strength within 24 hours.



IC-Loc™ Blue is a medium thickness, medium strength threadlock 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.

#301 Extender Tip
For use over BSI's standard #312 top. Can be used with all thicknesses of CA except IC-Gel. The flexible tip can be cut to the length and/or inside diameter that is needed for a particular application.

#303 Extra Long Extender Tip
For use over the standard #312 top, they provide a rigid tip with extended length to get thin and gap filling CA into hard to reach areas. They are very resistant to clogging and can be cleaned by soaking in acetone.

Well known throughout the hobby industry, Bob Smith Industries manufactures the finest in hobby, aerospace, marine and general adhesives. These fine products are made in the USA. Ultra Hobby Products now offers BSI epoxies, CyA glues, thread-lockers, accelerators and accessories. Go to the catalog page for the complete list of products available and prices.

BSI Insta-cure has a water thin viscosity that wicks deep into joints and cures within a few seconds. Surfaces to be bonded should be tight fitting and held together while curing. Thin CA glues give off a vapor and are fast setting and work very well for gluing balsa wood.



BSI Insta-cure+ is a thicker viscosity CA glue for bridging gaps and loose fitting items. It typically takes about 5 - 15 seconds to set-up. When gluing large pieces together it is best to lay down beads of Insta-cure+ about 1" apart and allow pressure to spread the glue.



BSI Maxi-cure is and extra thick CA glue that is best used when working with plastic, and is excellent for plastic model assembly. When used with accelerator is can be carved and sanded to achieve excellent results.



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.



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.
