The adhesive and sealing adhesive industry is an industry with multiple specialized terms. In order to help everyone understand the terminology in product information, we have compiled and summarized some of the following for everyone to learn and understand.

Glue: A substance that can bond two objects together and has sufficient strength at the junction. Generally composed of base materials, curing agents or catalysts, fillers, solvents, and additives.

Adhesion: The property of immediately forming equivalent bonding strength after slight pressure is applied to the adhesive in contact with the adherend.

Bonding: The state in which two surfaces are bonded together by chemical, physical, or a combination of both forces.

Adhesive: An object prepared for bonding or a substance that binds together after bonding.

Bonding: Use glue to connect the surfaces of the adhesive together.

Curing: The process of obtaining and improving bonding strength and other properties of adhesive through chemical reactions (polymerization, cross-linking, etc.).

Surface treatment: Chemical or physical treatment performed on the surface of the adhesive to make it suitable for bonding or coating.

Degreasing: Remove oil stains from the surface of the adhesive.

Polishing: The treatment of the surface of the adhesive with sandpaper, wire brush, or other tools.

Sandblasting treatment: The use of a sandblasting machine to spray a high-speed sand stream to treat the surface of the adhered material.

Chemical treatment: Place the adhesive in an acid or alkali solution for treatment, and use it to activate or passivate the surface.

Anodizing: The process of forming an oxide film on the surface of a metal substrate as an anode to protect it or make it suitable for bonding, using electrochemical methods.

Curing time: The time required for the adhesive to harden under certain conditions such as temperature and pressure.

Adhesive joint: The area where two adjacent adherends are bonded together using adhesive.

Storage period: The maximum storage time for adhesive to maintain its operational performance and specified strength under specified conditions.

Solid content: The percentage of non volatile substances in the adhesive measured under specified testing conditions.

Durability: The ability of adhesive components to maintain their performance for a long time under service conditions.

Bonding strength: The stress required to cause damage to the interface between the adhesive in the bonding sample and the adherend or its vicinity.

Shear strength: under the load parallel to the adhesive layer, the shear force borne by the unit bonding surface when the adhesive sample is damaged, expressed in MPa.

Tensile shear strength: under the axial tensile load parallel to the bonding interface layer, the stress causing the failure of the adhesive bonded joint, expressed in MPa.

Tensile strength: The tensile force borne by a unit adhesive surface when the adhesive sample is damaged under a load perpendicular to the adhesive layer, expressed in MPa.

Peel strength: The load that can be borne per unit width when the adhesive sample is separated under specified peel conditions, expressed in kN/m.

Impact strength: The work consumed per unit of the adhesive surface when the adhesive sample is subjected to impact load and fails, physically represented by J.
