Industrial Adhesive & Sealants

We can categorize adhesives in a number of different ways. First, we can group them per their curing method. Adhesives in this group include conductive adhesives, epoxy adhesives, hot melt adhesives, laminating adhesives, pressure sensitive adhesives, ultraviolet adhesives, and anaerobic adhesives.

In addition, we can divide these various adhesive types into groups of those made by one-part and those made by two-part formulas.

Finally, we can also categorize them by their physical form. Adhesives categorized this way include aerosol sprays, films, tape, foams, liquids, pastes, and solids.

Conductive adhesives, sometimes called thermally conductive adhesives, are those that conduct heat and electricity.

Epoxy adhesives are made from a dual chemical base epoxy. They are the most chemically resistant and strongest adhesive type available to consumers today. Some epoxies, known as conductive epoxies, are electrically conductive.

Hot melt adhesives use heat to harden the surface they are treating.

Laminating adhesives mount objects using a backing material. They are an example of a very common film adhesive.

Pressure sensitive adhesives, per their tactile nature, attach themselves to their assigned surface when someone or something applies pressure. Pressure-sensitive adhesives often come with backing designed to allow users to remove or reposition them without reducing or losing stickiness or damaging surfaces.

Ultraviolet adhesives work with the help of sunlight.

Anaerobic adhesive solutions cure when they are in an environment that lacks oxygen.

One-part adhesives bond to surfaces using only their latent bonding properties, which are activated by various energy sources. Energy sources vary by the type of adhesive, but some common examples include heat, moisture, and radiation. A version of the one-part formula is used to create ultraviolet adhesives.

Two-part, or multi-part, adhesive products require the mixture of two or more separate components. They are activated either through homogeneous mixing, which must take place immediately before application, or through the separate application and pressing together of these components. During the latter procedure, a chemical reaction occurs that allows the properties of the components to bond together. Multi-part adhesive formulas are used with acrylics, epoxies, and urethanes.

Aerosol spray adhesives provide a protective coating or seal to a variety of products. The types of products with which an aerosol spray can adhesive will work depend on the composition of the spray adhesive.

Film adhesives are chosen for use with products that require a uniform glue line, which they supply upon their activation via pressure and/or heat. Also, film adhesives may or may not come with release paper.

Tape, also called adhesive tape or seal tape, consists of a strip of material with an adhesive applied to one or both sides. Tape is a contact adhesive, meaning that it sticks upon contact.

Foam adhesives are adhesives that offer fast bonds and relatively quick curing times. Customers usually dispense them from a glue gun or special canister. Foam adhesives work exceptionally well as sealants of openings like the superficial cracks on the outside of a house.

Liquid adhesives are useful in a wide range of applications, from arts and crafts to product assembly. They can dry as clear adhesives or visible adhesives. Gap filling adhesives are a good example of a glue-like liquid or foam adhesive. Because they do not shrink much when set, customers can use gap filling adhesives as both bonding adhesives and sealants.

Paste adhesives are structural adhesives that provide a permanent, strong bond. They bond materials like stainless steel, titanium, and aluminum. Epoxy is one of the most common examples of a high strength paste adhesive.

Solid adhesive products include, among others chips, granules, hot melt sticks, pellets, and powder.
