−
A substance that adheres one surface to another. Adhesives provide a wide selection of properties, solubility, tackiness, bonding time, and bonding strength. They can be used on nearly every kind of surface, such as wood, glass, metal, plastic, paper, fabric, and rubber. Adhesives are usually activated by water, solvents, pressure, heat, cold, or UV radiation. In some cases, surface treatment, abrasion, or an adhesion promoter may be needed to increase the strength or durability of the adhesive bond. Adhesives may be classified as inorganic and organic adhesives.

Any non-metallic substance used to adhere one surface to another. Adhesives provide a wide selection of properties, solubility, tackiness, bonding time, and bonding strength. They can be used on nearly every kind of surface, such as wood, glass, metal, plastic, paper, fabric, and rubber. Adhesives are usually activated by water, solvents, pressure, heat, cold, or UV radiation. In some cases, surface treatment, abrasion, or an adhesion promoter may be needed to increase the strength or durability of the adhesive bond. Alternative binding techniques include sewing, mechanical fasteners and welding.

Examples of inorganic adhesives are [[water%20glass|water glass]], [[plaster%20of%20Paris|plaster of Paris]] and [[portland%20cement|portland cement]].

Adhesives may be classified as inorganic and organic adhesives:
 +
* Inorganic adhesives: [[water%20glass|water glass]], [[plaster%20of%20Paris|plaster of Paris]] and [[portland%20cement|portland cement]].  
 +
* Organic adhesives:  animal ([[hide%20glue|hide]], [[bone%20glue|bone]], [[blood%20glue|blood]], [[casein%20adhesive|casein]], etc.), or vegetable ([[starch|starch]], [[gum|gum]], [[natural%20resin|natural resin]], etc.) or synthetic ([[acrylic%20resin|Acrylic]], [[polyvinyl%20acetate|Vinyl acetate]], [[cyanoacrylate resin|Cyanoacrylate]], [[epoxy|Epoxy]], [[silicone adhesive|Silicone]], etc.). 
  
−
Organic adhesives may be subdivided by origins into animal ([[hide%20glue|hide]], [[bone%20glue|bone]], [[blood%20glue|blood]], [[casein%20adhesive|casein]], etc.), vegetable ([[starch|starch]], [[gum|gum]], [[natural%20resin|natural resin]], etc.) and synthetic ([[acrylic%20resin|acrylic]], [[polyvinyl%20acetate|vinyl acetate]], [[cyanoacrylate|cyanoacrylate]], [[epoxy|epoxy]], [[silicone|silicone]], etc.).

Description

Any non-metallic substance used to adhere one surface to another. Adhesives provide a wide selection of properties, solubility, tackiness, bonding time, and bonding strength. They can be used on nearly every kind of surface, such as wood, glass, metal, plastic, paper, fabric, and rubber. Adhesives are usually activated by water, solvents, pressure, heat, cold, or UV radiation. In some cases, surface treatment, abrasion, or an adhesion promoter may be needed to increase the strength or durability of the adhesive bond. Alternative binding techniques include sewing, mechanical fasteners and welding.

Adhesives may be classified as inorganic and organic adhesives:
