High-quality Materials for Micro-finishing

3M™ Diamond Microfinishing PSA Film Sheet 675L securely anchors micron-graded diamonds to a polyester film backing. Known for its durability, the polyester film backing assists in product flexibility and life. The sheets are also color coded by grade to help you reduce the risk of selecting the wrong grade.

Waterproof Backing and Easy Attachment

Polyester film backings are water resistant, so the abrasive may be run with a lubricant, which helps remove swarf and debris. This film also uses pressure sensitive adhesive, which allows for easy attachment, and can be removed without leaving any sticky residue.

Tips for Achieving Desired Roughness Average

Many micro-finished products require a specific Ra, or roughness average. To obtain the desired Ra when applying thermal spray coatings, 3M recommends following a unique sequence of steps tailored to the substrate. It is important for operators to consider these factors – Ra and substrate – when selecting the grade of film for this sheet.


  • Micron-graded diamond mineral delivers a wide range of surface finishes and stock removal for all customer requirements
  • Polyester film backing allows film to be used dry or wet with coolant
  • An exceptional product for thermal spray finishing of contour / complex shapes
  • Pressure sensitive adhesive allows for easy attachment and clean removal
  • Color coded to reduce the risk of error and mixing up abrasive grades
