Surface treatment prior to adhesive bonding

When using an adhesive to bond an object, the desired result is sometimes not achieved, and surface preparation is a major factor; indeed, the success or failure of the bond often hinges on how the surface is treated. During use, objects inevitably accumulate contaminants; if these are not thoroughly cleaned off prior to bonding, they interfere with intermolecular forces and result in a weak bond. So, how exactly should surface preparation be carried out before applying the adhesive?

Three Major Factors Affecting Adhesive Curing

The curing reaction of an adhesive is a process—involving chemical reactions such as polymerization and cross-linking—by which properties like bond strength are developed and enhanced. Curing is a critical step for achieving optimal bonding performance; maximum strength is attained only upon complete curing. The curing process is categorized into initial curing, primary curing, and post-curing.
