A type of structural adhesive made from acrylic, a manufactured polymer. Acrylic adhesives set rapidly and are very strong due to heavy cross-linking.
A substance used to join two or more materials. The pros and cons of adhesives relate specifically to how adhesives differ from the materials used for welding and mechanical fastening.
The process of binding materials together using any number of adhesive substances. Paste, glue, and tape are examples of common adhesives.
The inability of an adhesive to stick to a surface. During adhesive failure, the adhesive cannot bind two surfaces together and separates from the substrate.
A type of structural adhesive that can cure and harden only in an environment absent of oxygen.
A document that contains the instructions necessary to manufacture and/or assemble a part.
A joint formed by two surfaces that meet without overlap or complex intersection. Butt joints are often combined with other joint designs.
A heavy, colorless, odorless gas. Carbon dioxide can be used to extinguish fires fueled by adhesives or curing agents.
The backing material to which pressure-sensitive adhesives stick. The carrier acts as a mode of transport for the adhesive.
A material's ability to resist forces that attempt to pull an adhesive apart by separating rigid surfaces.
A force that pulls an adhesive apart by separating two rigid surfaces.
The inability of an adhesive to resist internal separation. During cohesive failure, the adhesive sticks to both surfaces, but cannot hold them together.
A type of synthetic adhesive made from acrylic, a manufactured polymer. Cyanoacrylates bond with surfaces very quickly.
The ability to resist stresses and deformation caused by vibration. Adhesives have stronger damping capability than mechanical fasteners.
In adhesive bonding, a device that holds an adhesive and ejects the adhesive onto a surface. Dispensers can be handheld or attached to a robot.
A solid consisting of very small particles in large numbers. Dry powder can be used to extinguish fires fueled by adhesives or curing agents.
A type of structural adhesive made from epoxy, a manufactured polymer. Epoxy adhesives can bond with a variety of surfaces and are strong and resilient.
A material consisting of a mass of small bubbles formed together into a type of semi-liquid. Foam can be used to extinguish fires caused by adhesives or curing agents.
A type of adhesive that requires heat for application and strengthens as it solidifies.
joggle lap joint
A variation of the lap joint design in which one surface area is straight, while the second forms an "S" shape.
The process of bringing and holding materials together by fastening, adhesive bonding, welding, or other similar processes.
The location at which an adhesive layer holds two surfaces together.
A joint formed when two surfaces overlap one another. Lap joints provide more stress resistance than butt joints.
A system of cameras and computers that can be programmed to complete tasks. Machine vision can be used to help assemblers locate defective products.
The process of joining two materials through the physical interaction of a common device, or fastener. Common mechanical fastening processes include bolting and nailing.
An adhesive made from naturally occurring living sources, such as plants and animals. Natural adhesives are also called organic adhesives.
A synthetic adhesive used for applications that do not require strong load-bearing capabilities. Nonstructural adhesives can be easily unbonded from surfaces.
An adhesive made from naturally occurring living sources, such as plants and animals. Organic adhesives are also called natural adhesives.
A material's ability to resist forces that attempt to pull an adhesive apart by separating flexible surfaces.
A force that pulls an adhesive apart by separating one flexible surface and one rigid surface.
PSA. An adhesive that needs only minimal pressure to stick to a surface.
A material's ability to resist forces that attempt to cause the internal structure of the material to slide against itself.
A force that attempts to cause the internal structure of a material to slide against itself.
A type of structural adhesive made from silicone. Silicone adhesives set as soon as they contact air.
A chemical material that attempts to dissolve another material. Solvents can be used to remove adhesives from a surface.
A joint design that combines the butt joint and lap joint. A butt joint is formed, and a third plank of material is then adhered to the area above the butt joint.
Any force that attempts to physically deform an object.
A synthetic adhesive with strong load-bearing capabilities. Structural adhesives are not easily unbonded from surfaces.
The surface material upon which an adhesive is applied to form a bond or joint.
A chemically manufactured adhesive derived from either thermoplastics or thermosets. Synthetic adhesives are commonly used in industrial settings.
A material's ability to resist forces that attempt to pull apart or stretch it.
A force that attempts to pull apart or stretch a material.
tongue and groove joint
A joint formed by inserting part of one surface material into a recessed area of a second surface. This joint design offers excellent stress resistance.
A type of structural adhesive made from urethane, a manufactured polymer. Urethane adhesives form flexible joints.
A fluid's resistance to flow. An adhesive must have low viscosity in order to fill the crevices of a surface. However, if the viscosity is too low, the adhesive will run off the surface and form no bond at all.
A joining process that uses heat, pressure, and/or chemicals to fuse two materials together permanently.
The process of spreading an adhesive over a surface. Proper wetting occurs when the adhesive fills all crevices of the surface.
