Mastic asphalt, or asphalt, is a sticky, black and highly viscous liquid; Mastic cold porcelain, or salt ceramic, is a traditional salt-based modeling clay. Mastic, high-grade construction adhesive commonly used to bond ceiling, wall, and floor tiles, plywood panels, concrete, asphalt, leather and fabric.
Mastic tears. Mastic (Greek: Μαστίχα) is a resin obtained from the mastic tree (Pistacia lentiscus). [1] It is also known as tears of Chios, [2] being traditionally produced on the island Chios, and, like other natural resins, is produced in "tears" or droplets.
tensile strength exceeds most woods, 2,200-3,00 pounds per square inch water-resistant, depending on alkalis used Woodworking, paper glue, fireproof laminates Medieval or earlier Soybean glue: As for casein glue, but using soy protein Soy protein is mixed with alkalis Albumin glues (blood glues and egg albumin adhesive, EAA)
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).

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]
The adhesive components in a liquid solution anchor themselves in irregularities on the substrate and eventually harden, providing sites on which to adhere. [6] Surface tension effects restrict the movement of the adhesive along the surface of the substrate, and is related to the thermodynamic work of adhesion by Dupre's Equation . [ 6 ]
Thread-locking fluid or threadlocker is a single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion. Most thread-locking formulas are methacrylate -based and rely on the electrochemical activity of a metal substrate to cause polymerization of the fluid.
