The mechanical interlocking theory of adhesion states that good adhesion occurs only when an adhesive penetrates into the pores, holes and other irregularities of the adhered surface of a substrate, and locks mechanically to the substrate 1). The adhesive must not only wet the substrate, but also have the right rheological properties to penetrate pores and openings in a reasonable time. [...] This method can significantly improve bond strength and durability by providing mechanical interlocking 50). Beyond mechanical interlocking, the enhancement of the adhesive adhesive resin cement joint strength due to the roughing of the adherend surface may also result from other factors such as formation of a larger surface, improved kinetics of wetting and increased plastic deformation of the adhesive.

The mechanical interlocking theory of adhesion states that good adhesion occurs only when an adhesive penetrates into the pores, holes and crevices and other irregularities of the adhered surface of a substrate, and locks mechanically to the substrate. The adhesive must not only wet the substrate, but also have the right rheological properties to penetrate pores and openings in a reasonable time.

[...] These pretreatments (especially plastic surface treatments) result in microroughness on the adherend surface, which can improve bond strength and durability by providing mechanical interlocking. Beyond mechanical interlocking, the enhancement of the adhesive joint strength due to the roughing of the adherend surface may also result from other factors such as formation of a larger surface, improved kinetics of wetting and increased plastic deformation of the adhesive.
