Template:Short description There are many adhesive substances that are considered or commonly referred to as glue. Historically, the term only referred to protein colloids prepared from animal flesh. The meaning has been extended to refer to any fluid adhesive. Template:Expand list

Plant- and animal-based adhesivesEdit

Type Subtypes Source(s) Manufacture Chemistry Volatiles Safety Properties Shelf life Working time Setting Strength Solvents Uses Date
Roasted hydrocarbons Tar, pitch, and asphalt/ bitumen Made from plants (especially wood) or fossil hydrocarbons natural or artificial destructive distillation Hydrocarbon goo of no specific chemical formula Emits Volatile organic compounds, especially when heated health effects understudied (see Asphalt#Health and safety) dark, viscous, more flexible when heated Indefinite, may stiffen Indefinite Reversibly becomes more flexible and fluid when heated water-repellant, Sealant, hafting prehistoric
Mixed-protein glues<ref>Template:Cite book</ref> Casein glue Milk, limestone and brine Milk curd is mixed with alkalis non-toxic (preservatives excepted) Once wet, 6–7 hours. ~4 hours for softwood, 8 for hardwood; must be under pressure for >0.5-2 hrs 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) blood (serum albumin) or eggs prehistoric
Gelatin glues hide glue, including rabbit-skin glue;

bone glue, and fish glue including isinglass

Animal connective tissue

and bones

hides are acid-treated, neutralized, and repeatedly soaked; the soaking-water is dried into chips hydrolyzed collagen Until it cools Thermoplastic. Somewhat brittle when set Water-soluble Cabinetmaking, bookbinding, lutherie, glue-size
Keratin glues Hoof glue and horn glue hooves of ungulates, animal horns Hooves or horns are fragmented, boiled into goo, and acidified partially- hydrolyzed keratin Until it cools Thermoplastic. Hardens as it cools, but does not become brittle Gluing and stiffening textiles, cabinetmaking, glass sealant
Fibrin glue human fibrinogen and human thrombin when two parts are mixed, they form fibrin 10–60 seconds converts to fibrin Medicine
Waxes Beeswax made by insects
Starch glues potato starch, rice glue, wheatpaste starches (plant energy-storage chemicals) Starch may be purified before being mixed with water; leaving gluten in makes a more permanent bond
Dextrin glues British gum, Coccoina usually derived from potato starch mid-19th century
Polysaccharide glues mucilage, agar, algin
Tree gums/resins Balsam (fir) resins, such as Canada balsam, Dammar gum, Gum Arabic (also called acacia gum), Mastic
Latex rubber cement

(cow gum)

latex, a coagulating plant fluid, also made synthetically latex is dissolved in an organic solvent organic solvent evaporates as it sets solvent may be hazardous; latex is an allergen
Methyl cellulose cellulose, a plant structural material, and methyl chloride heating cellulose with an alkali and reacting it with methyl chloride

Solvent-type gluesEdit

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Solvent adhesives temporarily dissolve the substance they are gluing, and bond by solvent-welding material together with the re-solidified material.

Synthetic polymer gluesEdit

Thermoplastic polymersEdit

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Thermoplastic glues including hot-melt adhesives cure reversibly as they cool, like the gelatin and keratin glues listed above. They frequently don't emit volatiles unless overheated.

Ethylene-vinyl acetate synthetic polyethylene mixed with about 11% vinyl acetate
Polyolefins (polyethylene, polypropylene, etc.) synthetic thermosetting
Polyamides synthetic
Polyesters synthetic
Polyurethanes synthetic
Polycaprolactone synthetic biodegradable very low melting temperature, Template:Cvt and heat conductivity means it can be moulded by hand. Can be used to mould itself.
  • Styrene acrylic copolymer – e.g. "No More Nails"

Thermosetting polymersEdit

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Thermosetting glues or thermosets cure irreversibly by polymerization. The polymerization can be triggered by heat or other radiation, or high pressure or a catalyst/hardener may be added.
