Adhesives are any materials meant to temporarily or permanently hold two or more objects together through surface contact.
Adhesives are best classified into categories based on the forms they come in: tapes, films, liquids, pastes, and solids. Strouse works specifically with Tapes and Films.
Tapes are the most popular form of adhesive. They come in roll form and can be converted into customized sizes, shapes, and forms as a finished good. Among adhesive tapes there are pressure sensitive adhesives (PSAs), water activated tape, and heat sensitive tape which each have a wide range of application usage in just about every industry.
Films are similar to tapes; they come in roll form and can be converted to custom shapes and sizes. Films are often used as a protective barrier or bonding materials with a smooth transparent substrate for electronic devices.
Liquid adhesives come in bottles, tubes, and other forms of sealed containers. This adhesive cures when it comes in direct contact with a surface or hardens from the moisture in the air. Liquids are used to fill voids and can be sprayed to cover large area applications.
Pastes come in sealed containers similar to liquid adhesives but are spread along surfaces to form a bond. Adhesive manufacturers have created one-part and two-part paste adhesive formulations for strong bonds to rubbers, metals, wood, plastics, and masonry.
Solid adhesives are typically used for very specific applications. The adhesive comes in sticks (such as hot glue-gun sticks), cartridges, or pellets. Their form makes the adhesive very clean and easy to store and handle.
