Structural Cyanoacrylate

Surface Insensitive (SI) Structural Cyanoacrylate (SCA)
Tech-Bond Solutions offers four Surface Insensitive (SI), polymer- enhanced Structural Cyanoacrylate (SCA) options.  All of our SI SCA options, used with our performance enhancing tools, deliver consistently superior results.   Our performance tools, whether the Activator/Accelerator, the Poly Prep or our unique Filler, intensifies the chemical reaction that occurs during the bonding process.  A stronger chemical reaction yields a stronger, more durable bond.

There are five different polymer-enhanced, Structural Cyanoacrylate viscosity options.  Viscosity is the measure of how thickness a liquid or adhesive is.  Most over-the-counter super-glues are too thin for the casual user to have effective control.

Viscosities:of our Structural Cyanoacrylates

  • SI Blue (100 cP) is our standard viscosity. SI Blue spreads easily, wicks well and offers more control than the ultra-thin super-glues.  SI Blue is recommended for most tasks whether in the home, in the shop, in the garage, on a car, etc.

Available in 3 gm tubes, 20 gm, 1 oz, 2 oz, 8 oz, and 16 oz bottles.  Larger volumes up to container size are available with any of out adhesives.  Picture below.

SI Blue- Structural Cyanoacrylate (SCA)
SI Blue – Bottle sizes available – 20 gm to 1 lb.

A link to purchase SI Blue appears below.

Other viscosities available:

  • SI Black (1500 cP) is thicker and offers more control. Besides being easier to control, SI Black may handle ambient moisture better.  Use SI Black when gap filling (up to .0059 in.), or when working on an upright surface.

Available in 1 oz, 2 oz, 8 oz, and 16 oz bottles and up to container size.

  • SI Green (0-5 cP) is our ultra-thin structural adhesive. Ultra-thin adhesives actually rate slightly higher in tensile and shear strength than higher viscosity formulations.  For the technician or hobbiest, ultra-thin viscosity CA’s can be difficult to use because of their runniness.

Available in 1 oz, 2 oz, 8 oz, and 16 oz bottles and up to container size.

  • SI Brown (600 cP) is a medium viscosity Surface Insensitive (SI), Structural Cyanoacrylate (SCA).  SI Brown is often favored by manufactures because they offer a 600 viscosity adhesive offers good control without being too thick.

Available in 1 oz, 2 oz, 8 oz., and 16 oz bottles and up to container size.

  • SI GEL is our thickest Structural Cyanoacrylate. Offers maximum gap filling and control.

Available in 3 gm and 20 gm tubes, 300 ml caulking tubes and larger sizes.

Attributes of our polymer-enhanced, Surface Insensitive (SI), Structural Cyanoacrylates (SCA’s).

  • dry clear
  • remain flexible when bonding flexible materials
  • provide structural strength.
  • In the 20 gm, 1 oz and 2 oz bottle sizes are guaranteed not to harden 2 for two years
  • Repairs are completed quickly, easily and permanently.

Other Structural Adhesives

BP Blue – (specialty adhesive for polymers and poly-plastics)
A structural cyanoacrylate designed to work with poly-plastics (polyethylene, polypropylene, polyurethane, etc. and our space age polymers like Teflon®, Delrin®, UHMW, silicone rubber, et al.   BP Blue can used by itself (one step) or the chemical reaction is enhanced with the proper usage of our standard Activator/Accelerator (AA).  Attributes are the same as our SI Structural Adhesives
Available in 20 gm, 1 oz, 2 oz, 8 oz, and 16 oz bottles and up to container size.

Other Adhesives
Foam Safe Cyanoacrylates
Cyanoacrylates (CA’s) will melt open cell foams.  Some individuals are sensitive to the odor that can occur with CA’s.  Some over-the-counter CA’a fog clear materials such as plexiglass or clear plastics.  Our Foam Safe Bonding Agents work with open cell foams, have a greatly reduced odor and do not outgas, or fog, clear materials.
Our Foam Safe Cyanoacrylates include:
•    Foam Safe Blue (FB) is a standard viscosity (100 cP), low odor, low bloom cyanoacrylate that will not   affect Depron®, foam core, styrenes and other open cell foams.
•    Foam Safe Red (FR) is a medium-thick viscosity CA (1000 cP) that has the same performance characteristics that Foam Safe Blue has.  Being thicker can make Foam Safe Red easier to use.
Available in 20 gm, 2 oz and larger sizes.

The downside of a foam safe CA is that they are not as strong as a standard cyanoacrylate.  Note:  Foam Safe CA’s work MUCH easier when a Foam Safe Accelerator (AH) is used.

Thread-locking fluids are thin, single-component adhesives which are applied to the threads of metal screws and bolts to prevent loosening, leakage, and corrosion. Typically, thread-locking fluids cure anaerobically and are methacrylate-based.


TL 42 is a low viscosity adhesive that offers medium torque removal resistance.
TL 71 is a low viscosity adhesive that offers a high level of torque removal resistance.
TL 90 is a very low viscosity adhesive (wicking grade) that offers medium torque removal resistance.

Applications for threadlockers include: appliances, general industry, hobby, construction, repair, transportation, maintenance, heavy machinery, motorcycle, aerospace and agricultural equipment.
Available in 10 ml, 50 ml and larger sizes.

Performance Tools

Standard Activator/Accelerator (AA)
Applied properly, our standard Activator/Accelerator intensifies the chemical reaction of the bonding process producing a stronger, more durable bond.  In addition, our standard Activator/Accelerators:speed the cure of our structural cyanoacrylates and can be used as a cleaner.
Available in 1 oz, 2 oz, 8 oz, 16 oz and larger sizes.

Foam Safe Accelerators (AH)
Foam Safe Accelerators are designed to work with our foam safe cyanoacrylates but they speed the curing of all Tech-Bond bonding agents.  In addition, Foam Safe Accelerators can be safer for some fine finishes.
Available in 1 oz, 2 oz, 8 oz, 16 oz and larger sizes.

Poly Prep
Tech-Bond’s Poly Prep is our surface primer for polymers that allows our structural adhesives to work with virtually all materials, such as polyethylene, UHMW’s, silicone, Delrin(R), polypropylene, nylon, polyester, Teflon®, polyurethane, polyester, etc.  As part of its actions, our Poly Prep etches the plastic, but note that it dries clear amd does not damage most finishes (test first).
Available in 1 oz., 80 ml, 8 oz., 16 oz., 1 gallon and larger sizes.

Our Filler is a silica sand compound that will, when used with our structural adhesives, fill holes and cracks including stripped out screw holes.  With a stripped our screw hole is drilled, that hole can be immediately drilled and tapped.
Available in 35 gm, 70 gm, 8 oz. and larger sizes.

Tech-Bond’s Debonder dissolves Structural Cyanoacrylates, cyanoacrylates, superglues, etc., on contact.  Our Debonder is generally safer on finishes than Acetone, the other “undo” option.
Available in 1 oz., 2 oz., 8 oz. and larger sizes.
