A glue gun (shown at right) is one method of applying hot adhesives. The glue gun melts the solid adhesive, then allows the liquid to pass through its barrel onto the material, where it solidifies. Thermoplastic glue may have been invented around 1940 by Procter & Gamble as a solution to the problem that water-based adhesives, commonly used in ...
Adhesives may be broadly divided in two classes: structural and pressure-sensitive. To form a permanent bond, structural adhesives harden via processes such as evaporation of solvent (for example, white glue), reaction with UV radiation (as in dental adhesives), chemical reaction (such as two part epoxy), or cooling (as in hot melt).
The gun uses a continuous-duty heating element to melt the plastic glue, which the user pushes through the gun either with a mechanical trigger mechanism on the gun, or with direct finger pressure. The glue squeezed out of the heated nozzle is initially hot enough to burn and even blister skin. The glue is sticky when hot, and solidifies in a ...
Structural adhesives can be used to create load-bearing joints. Although many adhesives such as sealants, hot melt adhesives and even acrylic foam tapes can bear loads, the term structural adhesive is typically used where joints will have lap shear strength greater than 1450 psi. [3] The different types of structural adhesives are: Epoxies
Glue sticks are solid and hard adhesives in twist or push-up tubes. Users can apply glue by holding the open tube to keep their fingers clean and rubbing the exposed stick against a surface. Users can apply glue by holding the open tube to keep their fingers clean and rubbing the exposed stick against a surface.
Cyanoacrylate is used in archery to glue fletching to arrow shafts. Some special fletching glues are primarily cyanoacrylate repackaged in special fletching glue kits. [25] Such tubes often have a long, thin metal nozzle for improved precision in applying the glue to the base of the fletching and to ensure secure bonding to the arrow shaft.

"Super glue" is a formulation of cyanoacrylate. Polymethyl methacrylate is the clear break-resistant sheeting sold as acrylic glass (or simply acrylic sheet) or under the trade name Plexiglas, Perspex, etc. Polyacrylates are used in cosmetic products as rheology modifiers and film formers, and these are typically polymers of acrylic acid fluids.
