Provides Dimensional Stability and Improved Handling for Die-Cutting and Lamination
The acrylic adhesive on 3M Differential Double Coated Silicone Tape 9699 offers excellent shear resistance and high adhesion to a variety of high surface energy substrates. The silicone adhesive provides good bond to silicone rubber and strong holding power to various silicone surfaces. The polyester carrier provides dimensional stability and improved handling with ease of die cutting and lamination.
Recommended Applications
- Silicone gasket bonding
- Attaching silicone rubber to other substrates
- Reducing/eliminating buzzes, squeaks and rattles
- General purpose silicone foam attachment
- Bonding dissimilar materials
- Bonding to silicone foam and silicone rubber keypad placement
Adheres without Priming on Silicone Rubbers, Foams, Polypropylene and More
3M Differential Double Coated Silicone Tape 9699 offers a unique solution for wide web lamination of silicone materials (e.g. foams, rubber, films, etc.) to many other surfaces, including low surface energy materials. Adheres without priming on contact to hard-to-bond surfaces such as silicone rubbers and foams; polypropylene, polyethylene, other low surface energy materials and more. It is most commonly used for silicone foam and silicone rubber keypad placement.
Environmental Performance
The bond strength of 3M Differential Double Coated Silicone Tape 9699 increases as a function of both time and temperature. When properly applied, this tape withstands the effects of UV exposure and numerous chemicals, including oil, mild acids and alkalis. It is heat resistant for short periods (minutes, hours) at temperatures up to 350_F (177_C) and for intermittent longer periods (days, weeks) up to 250_F (121_C).
