Direct measurement of the adhesion of surface coatings is still a challenge. Several adhesion test methods came into use to evaluate the adhesion of their coatings and also to determine the applicability of the products in industrial practice. The parameters of adhesion testing are used to evaluate the friction work, acoustic emission activity and critical load of the scratch test, the critical strain and the defect density of the four-point bending test, the proportional damage area of the cavitation test, the critical number of loading cycles of the impact test. The adhesion testing procedures used for diamond-coated carbide inserts are the indentation method and physical machining.

Adhesive Binders are binders for paper coating compositions. The modified soy protein has found extensive use as an adhesive binder in paper coating compositions. They are typically prepared from isolated soy protein extracted from oil free soybean flakes in an alkaline solution and recovered by is electric precipitation. The recovered soy protein is then typically modified by hydrolysis and other chemical treatment to prepare a protein adhesive material suitable for use as a binder in paper coating compositions. These binders find usage in the paper coating industry. These high solids adhesive binder solutions can be prepared both using cold water and using water which has been heated.

Adhesive Cements are used for bonding, insulating, and encapsulating applications. Thermally conductive and electrically insulating cements paste the material bonds, metal, ceramics and glass. It is also available in powder form. It should be remixed before use.
