Adhesion promoter

An adhesion promoter (primer) is a chemical substance used to improve adhesion between two different materials. These are usually materials that do not usually bond well due to different chemical or physical properties. An adhesion promoter is used to create a strong and permanent connection between these materials.

Adhesion promoters are used in many different applications. Examples of this are the production of composite materials, the coating of surfaces, the bonding of plastics or the treatment of metals. An adhesion promoter can help to improve adhesion and thus the strength of the connection between the materials.

There are many different types of adhesion promoters, each designed for specific applications. Examples of this are silanes, which are used to bond glass fibers to synthetic resins, or epoxy resins, which are used to bond metals to plastics. Choosing the right adhesion promoter depends on various factors, such as the type of materials to be joined, the environment in which the joint will be used, or the desired strength of the joint.

Overall, a bonding agent is an important part of many industrial processes as it helps create a strong and durable bond between materials that do not normally bond well.
