WHAT ARE THE DIFFERENT TYPES OF ADHESIVE?

Adhesives types can be classified in material and function, such as Epoxy / Urethane / Methacrylate / Instant Adhesive / Contact Adhesive / IQ Glue / Wood, Paper & Fiber Adhesives / PermaTack / Threadlockers.

On the others hand: Water Based, Thermal Adhesives, Two Part Adhesives, Moisture Cure Adhesives, Ultraviolet Cure Adhesives, Cyanoacrylate Adhesives, Anaerobic Adhesives, Film Adhesives.

TYPE	EXAMPLE	HOW IT BONDS	USES	STRONG POINTS	WEAK POINTS	TIPS
PVA – White/Yellow Glues	Elmer’s, Tilebond	Physically interlocks materials	Porous Materials – Wood, Paper	Water-based, easy clean-up, long open time, Heat/moisture to reverse bond	Needs clamping while setting. Slow setting	Use sizing on really porous materials, like wood endgrain
Epoxy		Physically interlocks and chemically bonds materials	Bonds most substrates	Very strong and tough, various cure times available.	Needs clamping while setting, Not reversible	Allow to partially cure before application for small parts that aren’t easily clamped
Solvent Cements	Tenax, Plastruct, Testors, Acetone, Methyl ethyl ketone (MEK)	Dissolves plastics, which then re-harden, similar to welding	Polystrene and acrytic plastics – Each kind of plastic will require a different solvent	Very strong bond, quick set and cure time	Will dissolve or distort think materials. Generally not reversible	For straight solvent, use touch-n-flo to apply cement directly to jointly, otherwise, use very small brush.
Cyanoacrylate	Zap, Cyanopoxy	Binds to water and hydroxyl groups on substrate surface	Bonds just about all non-porous materials	Very strong bond	Brittle, low shear strength, Gap-filling cement somewhat better	Use thin CA where you can make tight joints, thick CA for looser joints
Contact Adhesive	Goo, Barge Cement	Viscosily of adhesive holds materials together	Bonding dissimilar materials, like wood and plastic, metal and plastic	Stick almost anything	Creep, joint failure. Solvent may affect plastics	Vinyl floor adhesive is water-based, good for non-structural, dissimilar joints.
Polyurethane	Gorilla Glue	Interlocks and binds to water/hydroxyl	Bonds many substrates	Water-proof, expands to fill gaps while setting	Expands while setting, so must be clamped while setting	Moisture-catalyzed, short shelf life after opening. Keep opened container as dry as possible.
