MED 9302SF

Double-Coated Polyester with a Silicone and a Modified Acrylic Adhesive

MED 9302SF is a 5.7 mil double coated polyester with a silicone adhesive on the laminating side and a modified acrylic adhesive on the mounting side and a double liner system. It is designed for bonding silicone foams and rubber adhesive to medium and high surface energy materials. MED 9302SF is commonly used in automotive and general industrial applications.


Typical Application

It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry, and free of grease or oil. Bond strength is dependent upon the amount of adhesive-to-surface contact developed.*

*Note that different pressure, time and temperature on different (film/rigid) surface achieves different performance.


Features and Benefits
  • Double linered, double coated tape construction with a differential adhesive system
  • Multipurpose silicone adhesive on the laminating side
  • Modified acrylic adhesive for low surface energy substrates on the mounting side
  • Polyester film carrier
  • Poly coated kraft primary release liner and polyester process liner
  • Dimensional stability and good die cutting characteristics
  • Strong bond to silicone rubber and silicone foam
  • Strong bond to low surface energy materials
  • High tensile strength and good converting performance
  • Good moisture stability and lay flat properties
  • Two-year warranty
