![]() Bond strength is dependent upon the amount of adhesive-to- surface contact developed.Typical surface cleaning solvents are IPA/ water mixture (rubbing alcohol) or heptane.* (Steps A and B) To obtain optimum adhesion, the bonding surfaces must be well unified, clean and dry.Unique Materials: Special surface preparation may be needed for glass and glass-like materials, copper and copper containing metals and plastics or rubber that contain components that migrate (e.g.need to be sealed to provide a unified surface. Porous Surfaces: Most porous and fibered materials such as wood, particleboard, concrete etc.Adhesion Promoters: Priming a surface can significantly improve initial and ultimate adhesion to many materials such as plastics and paints.Abrasion: Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt or oxidation and can increase surface area to improve adhesion.Heavy Oils: A degreaser or solvent-based cleaner may be required to remove heavy oil or grease from a surface and should be followed by cleaning with IPA/water.There are exceptions!Įxceptions to this general procedure that may require additional surface preparation include: ![]() Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA) and water* prior to applying 3M™ VHB™ Tapes.
