Liquid animal glue. The earliest evidence of human adhesive use was discovered in central Italy when three stone implements were discovered with birch bark tar indications. The tools were dated to about 200,000 before present in the Middle Paleolithic. It is the earliest example of tar-hafted stone tools. [4]
2-Octyl cyanoacrylate is a cyanoacrylate ester typically used as a wound closure adhesive (under the brand name Dermabond). [1] It is closely related to octyl cyanoacrylate . The use of 2-octyl cyanoacrylate was approved in 1998; offered as an alternative to stitches, sutures, and or adhesive strips.
2-Ethylhexyl acrylate is a colorless liquid acrylate used in the making of paints, [2] plastics [3] and adhesives. [4] It has an odor that has been variously described as pleasant [ 5 ] or acrid and musty.
Most glue sticks are designed to glue paper and card stock together and are not as strong as some liquid-based variants. They can be used for craft and design, office use, and at school. There are several varieties: permanent,washable, acid-free,non-toxic, solvent-free, and dyed (e.g. to see where the glue is being applied).
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 ...
Moisture-curable polymers are used as electrical insulation in some kinds of cables and for water pipe in under-floor heating installations. Vinyltrialkoxysilanes are also used as a coupling agents or adhesion promoters for treatment of glass fibers and particulate minerals in order to form stronger bonds with resin and produce fiberglass with ...
Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps. [7] Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to metal cans, wood to china, and leather to pasteboard. [ 8 ]
