A

Accelerator, Activator – Terms used to describe the materials which initiate the polymerization needed to cure anaerobic, cyanoacrylate and modified acrylic adhesives.  At Permabond we use the term INITIATOR for the products used to cure surface activated acrylics.

Accelerator – Examples of Permabond accelerators for cyanoacrylate include QFS16 and CSA-NF.

Activator – Activators used with Anaerobics often called Anaerobic Surface Conditioners are used to accelerate cure on passive metals or allow cure with non-metallic surfaces.  They are also used to increase the maximum gap the anaerobic adhesive or sealant will cure through.

Acrylic Adhesive -Acrylic adhesives are adhesives that are made of acrylic or methacrylic polymers.The most common types of acrylic adhesives are two-component acrylic adhesives and no mix surface activated acrylic adhesives. Both are structural adhesives.

Acrylic Glue – Acrylic glue is a casual term for acrylic adhesive which are adhesives that are made of acrylic or methacrylic polymers.  The most common types of acrylic adhesives are two-component acrylic adhesives and no mix surface activated acrylic adhesives. Both are structural adhesives.

Adherend (or Substrate) – Material which is being joined or bonded.

Adhesion Chemistry – The science and study of the state in which two components join by either interlocking action or intermolecular forces at the adhesion junction.

Adhesive – Substance for bonding, sticking or holding things together.

Adhesive, Acrylic – Acrylic adhesives are adhesives that are made of acrylic or methacrylic polymers. The most common types of acrylic adhesives are two-component acrylic adhesives and no mix surface activated acrylic adhesives. Both are structural adhesives.  They offer fast fixture, cure at room temperature, and form strong bonds to many materials including glass, metal, plastics, and composites.

Adhesive, Anaerobic – An adhesive which only cures when air is excluded, and metal ions are present, and metal ions are present.  Uses include threadlockers, retaining compounds, form in place gaskets, and thread sealants.

Adhesive, Cyanoacrylate – Group of adhesives which show “instant” cure properties and bond to a wide variety of substrates. Cure is by contact with alkaline materials. Weakly alkaline materials, such as water, cause the cure to start. Cyanoacrylate adhesives are commonly referred to as super glue, instant adhesive, crazy glue, loca glue or ca glue.

Aging, Heat – Artificial “aging” of adhesive by exposing to elevated temperatures for long periods.

Ambient Conditions – Temperature, humidity, sunlight, etc. which exist in the area surrounding the bond, normally room temperature, atmospheric pressure, daylight, etc.

Anaerobic Adhesive – An adhesive which only cures when air is excluded.

B

Bead on Bead Acrylic Adhesive– Bead on Bead acrylic adhesives are two-component acrylic adhesives which are not mixed via a static mix nozzle but applied as a bead of part A followed by a bead of part B on top of the bead of part A.  Sufficient mixing occurs when the components are assembled to initiate cure.  Bead on Bead acrylic adhesive provides fast fixture and cure at room temperature.

Bond– Interface of the adhesive and the substrate.

Breakaway Torque – Measure of force needed to initiate movement of an unseated fastener in a loosening direction.
