2. Liquid optically clear adhesive - Wikipedia

   en.wikipedia.org/.../Liquid_optically_clear_adhesive

   Liquid optically-clear adhesive (LOCA) is liquid-based bonding technology used in touch panels and display devices to bind the cover lens, plastic, or other optical materials to the main sensor unit or each other. These adhesives improve optical characteristics and durability.

3. Index-matching material - Wikipedia

   en.wikipedia.org/wiki/Index-matching_material

   Certain optical components, such as a Wollaston prism or Nicol prism, are made of multiple transparent pieces that are directly attached to each other. The adhesive is usually index-matched to the pieces. Historically, Canada balsam was used in this application, but it is now more common to use epoxy or other synthetic adhesives.

4. Optical bonding - Wikipedia

   en.wikipedia.org/wiki/Optical_bonding

   Silicone: The most commonly found adhesive in optical bonding processes that dates back to the 1970s as a solution. [citation needed] Silicone's core properties of low conductivity and chemical reactivity, thermal stability, and ability to repel water and form watertight seals make it a common solution for optical bonding. Also, because it is a ...

5. Adhesive bonding - Wikipedia

   en.wikipedia.org/wiki/Adhesive_bonding

   The disadvantage of the lack of instantaneous bonding exhibited by many adhesives can be overcome by using a suitable fast-curing adhesive or a combination of a standard adhesive with a second, fast-curing adhesive (e.g. double-sided adhesive tape) or with another joining method, such as spot welding, rivets, screws, or clinching / press ...

6. Cyanoacrylate - Wikipedia

   en.wikipedia.org/wiki/Cyanoacrylate

   Chemical structure of ethyl cyanoacrylate, the precursor to many commercial adhesives. The most common monomer is ethyl cyanoacrylate.Several related esters are known. To facilitate easy handling, a cyanoacrylate monomer is frequently formulated with an ingredient such as fumed silica to make it more viscous or gel-like.

7. Pressure-sensitive adhesive - Wikipedia

   en.wikipedia.org/wiki/Pressure-sensitive_adhesive

   In contrast, pressure-sensitive adhesives (PSAs) form a bond simply by the application of light pressure to marry the adhesive with the adherend. Pressure-sensitive adhesives are designed with a balance between flow and resistance to flow. The bond forms because the adhesive is soft enough to flow, or wet, the adherend.
