Preparing Surfaces for Application of 3M™ VHB™ Tapes

 

Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA) and water* prior to applying 3M™ VHB™ Tapes. There are exceptions!

 

Exceptions to this general procedure that may require additional surface preparation include:

  • 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.
  •  
  • Abrasion:Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt or oxidation and can increase surface area to improve adhesion.
  •  
  • Adhesion Promoters:Priming a surface can significantly improve initial and ultimate adhesion to many materials such as plastics and paints.
  •  
  • Porous Surfaces:Most porous and fibered materials such as wood, particleboard, concrete etc. need to be sealed to provide a unified surface.
  •  
  • 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. plasticizers).
