About Cyanoacrylate Adhesives

Cyanoacrylate adhesives are one-part acrylate adhesives that cure instantly on contact with mated surfaces through a reaction with surface moisture. Cyanoacrylates are often called super glues.  Cyanoacrylate adhesives have high strength, excellent adhesion to a wide variety of substrates, especially plastics. Poor shock or impact resistance (brittleness) and poor gap filling abilities are potential disadvantages of cyanoacrylate adhesives. Rubber or elastomer modified cyanoacrylates and accelerators have overcome some of these problems. 

Important specifications to consider when selecting between cyanoacrylate adhesives include viscosity, initial set time, gap fill, tensile strength (UTS), and use temperature.  Viscosity is a measurement of a fluids resistance to flow.  Water is lower in viscosity than oil or honey. Oil is lower in viscosity than tar or molasses.  Depending on the application method, the viscosity controls the amount of cyanoacrylate adhesives dispensed onto a substrate.  Working, assembly or initial set time is the amount of time an adhesive, sealant or cement can be applied and repositioned or removed before extensive setting or curing and results in hardening of the bond joint. After this time, further movement or assembly adjustments would be difficult and possibly damage the finished bond.  Gap fill is the spacing or gap between the substrate that the cyanoacrylate adhesive can accommodate and still maintain a functional, full strength bond.  The ultimate tensile strength (UTS) is the amount of applied stress required to cause failure in a control specimen of the material under tensile load conditions. Use temperature is the range that the cyanoacrylate adhesive can be exposed to without degradation of structural or other required end-use properties.

Products & Services Related to Cyanoacrylate Adhesives

Conformal Coatings
Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.
Epoxy Adhesives
Epoxy adhesives are chemical compounds for joining components. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage.
Gel Elastomers
Gel elastomers are highly viscoelastic polymer gel materials that have excellent shock absorption and damping characteristics. They are available in a variety of material types and grades.
Pressure Sensitive Adhesives (PSA) and Contact Adhesives
Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms.
Silicone Adhesives and Sealants
Silicone adhesives and sealants have a high degree of flexibility and a very high temperature resistance (up to 600° F), but lack the strength of other epoxy or acrylic resins.
Thermoplastics and Thermoplastic Materials
Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.
Thermosets and Thermoset Materials
Thermosets and thermoset materials are crosslinked polymeric resins that are cured or set using heat or heat and pressure. They generally have a higher resistance to heat than thermoplastics.
