2. Hot-melt adhesive - Wikipedia

   en.wikipedia.org/wiki/Hot-melt_adhesive

   High heat resistance, good low-temperature flexibility. [28] Lower strength than polyesters. They usually have A-B-A structure, with an elastic rubber segment between two rigid plastic endblocks. High-strength film formers as standalone, increase cohesion and viscosity as an additive.

3. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   J-B Weld epoxy is a two-part adhesive that can bond various surfaces and withstand high temperatures up to 500 °F (260 °C) constantly and 600 °F (316 °C) for short periods. It is water-resistant, petroleum/chemical-resistant, acid-resistant, and resists shock, vibration, and temperature fluctuations.

4. Pressure-sensitive adhesive - Wikipedia

   en.wikipedia.org/wiki/Pressure-sensitive_adhesive

   Styrene block copolymers (SBC), also called styrene copolymer adhesives and rubber-based adhesives, have good low-temperature flexibility, high elongation, and high heat resistance. They are frequently used in hot melt adhesive applications, where the composition retains tack even when solidified; however non-pressure-sensitive formulations are ...

5. Chemistry of pressure-sensitive adhesives - Wikipedia

   en.wikipedia.org/wiki/Chemistry_of_pressure...

   The high tack material is a polymer with low glass transition temperature and high entanglement molecular weight, whereas the low tack polymer has high glass transition temperature and low entanglement molecular weight. [6] The high tack material comprises about 95% of the adhesive and provides the majority of the adhesive's tackiness. [6]

6. Adhesive bonding - Wikipedia

   en.wikipedia.org/wiki/Adhesive_bonding

   When bonding plastics, in particular with solvent-based adhesives, diffusion processes can also play a role. In this case, the plastic at the substrate surface is dissolved by the solvent contained in the adhesive. This leads to an increased mobility of the plastic's polymer chains, which in turn allows penetration by those of the adhesive.

7. Adhesive - Wikipedia

   en.wikipedia.org/wiki/Adhesive

   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 packaging at that time, failed in humid climates, causing packages to ...
