Surface Preparation For Successful Bonding
One of the major elements in determining the performance of an adhesive is to select a surface treatment that will assure adequate adhesion, prolong the service life of the adhesive system and ensure component integrity.
Metallic, as well as non-metallic, substrates contain surface contaminants. Contaminants on metallic surfaces may include oxides, paint, lubricating oils, greases and rust inhibitors. Non-metallic surfaces such as plastics, rubbers and polymers may have mold release agents, talcs, plasticizers and residues present that will inhibit proper adhesion.
The choice of surface preparations may include solvent cleaning, the use of etchants, mechanical abrasion and, if needed, special treatments that will optimize bond strength and durability. Issues such as environmental impact, budgetary considerations, facility use and equipment selection are always considered.
