3M Gasket Attachment Tapes and Adhesives

As a 3M master converter, Tekra offers a wide variety of 3M products used within gasket applications. A gasket is typically referred to as a seal between two surfaces that prevents leakage from or into joined objects. Selecting the right material for your unique gasket and application will determine product success or failure. It is crucial to select the right attachment material to ensure success. Tape selection affects gasket functionalities such as seal, corrosion prevention, vibration, and more.

Typical requirements for gasket attachment:

  • Easy and fast application of tape or adhesive
  • Strong environmental and chemical resistance
  • High adhesion to foams, rubbers and other difficult-to-bond substrates

Tekra has the products and industry knowledge to help you select the correct tapes for your application. Common products used in gasket manufacturing include 3M™ VHB™ Tapes, 3M™ Adhesive Transfer Tapes, and 3M™ Double Coated Tapes. This product portfolio can offer you a range of options for your attachment needs.

Tape for Foam Gasket Attachment

Due to its effectiveness in sealing, cushioning, mounting, and insulating foam gaskets are increasingly popular. Tekra offers a variety of products ranging from transfer tapes to 3M™ VHB™ tapes depending on your application and process. Below are a some of the most common tapes used for foam gasket attachment.

3M™ Adhesive Transfer Tape 9775WL+

  • Excellent bond to various fabricated foams, fabrics and substrates
  • Has good shear strength at elevated temperatures

3M™ VHB™ Tape 5925

  • Very conformable, double-sided, pressure sensitive, closed-cell acrylic foam tape
  • High strength, durable, with a clean appearance

3M™ VHB™ Tape 4941

  • Greatest strength
  • Very conformable, double-sided, pressure sensitive, closed-cell acrylic foam tape

Tape for Rubber Gasket Attachment

Time tested and reliable rubber gaskets are an industry go-to. Rubber gaskets are known for their strength, thickness, and stability. Depending on end-use application and market, 3M™ VHB™ Tape is a reliable option for rubber gasket attachment. In addition, traditional thin bonding materials offered by 3M like double coated tapes and adhesive transfer tapes are applicable.

3M™ Double Coated Tape 9495LE

  • Film carrier adds dimensional stability to foams and other substrates
  • Easier to handle tape during slitting and die-cutting
  • Bond strength of 3M™ Laminating Adhesive 300LSE increase as a function of time and temperature
  •  Very high initial adhesion

3M™ Double Coated Tape 9629B

  • Excellent adhesion to difficult to bond to surfaces such as HDPE, LDPE, and PP
  • Super quick stick
  • Higher adhesion from a thinner tape
  • Excellent solvent resistance

3M™ Adhesive Transfer Tape 9471LE

  • Reliable bonding to a wide variety of similar and dissimilar materials such as metals, most plastics, glass, papers and painted surfaces.

Tape for Silicone Gasket Attachment

By providing superior resistance to chemicals, silicone gaskets have proven use in medical devices. When addressing tapes and adhesives in a silicone gasket, tapes must not only need to adhere to silicone-based substrates, but they must also provide robust product performance in high temperature applications. In addition, tapes offering primer less bonding can improve productivity in the gasket manufacturing process. 

3M™ Double Coated Tape 9731

  • Ideal for attaching silicone rubber elastomers and foam
  • Features acrylic and silicone adhesives for specialized applications such as silicone gasketing
  • 3M™ Adhesive 350 on the face side provides exceptional temperature and chemical resistance
  • 3 mil silicone adhesive on liner side bonds well to silicone substrates
  • Polyester carrier provides dimensional stability and improved handling with ease of die cutting and lamination
