Avery Dennison Launches Industry's First Dedicated Electronic Parking Brake Pressure-Sensitive Adhesive

Press release date: October 12, 2011

New EPB Offering Highlights an Extensive Range of Adhesives for Brake Applications PAINESVILLE, Ohio - A new brake shim adhesive that withstands the high heat and pressure challenges associated with electronic parking brakes (EPB) while providing excellent damping characteristics has been introduced by Avery Dennison Performance Tapes. The new adhesive is the automotive industry's first brake shim pressure-sensitive adhesive solution engineered specifically to meet electronic parking brake performance challenges. The tape offers best in class damping at 100 C/212 F, and resists adhesive bleed at temperatures >150 C/302 F and pressures at >200 bars.

According to Gulsah Metinoz, global product manager, Avery Dennison Performance Tapes, the new EPB adhesive is engineered to reduce noise, vibration and harshness.

"The new Avery Dennison EPB adhesive is the only product that can solve the problem of bonding an EPB shim onto the pad for long-term service and at the same time offer a noise reduction benefit," she says. "Others can't do that. Prior to this product introduction, design engineers had to settle for short service life or else compromise on the quality of the sound level.

"Brake shim adhesives bond the shim to the brake pad," Metinoz continues. "With the automotive industry's new generation of electronic parking brakes, which is rapidly gaining market share worldwide, the pressure on the brake pad and shim is much higher than with conventional parking brakes. Plus, they produce much higher temperatures. As a result, existing brake shim adhesive products do not work satisfactorily. The pressures are so much higher that they squeeze the adhesive out from between the shim and pad. With electronic parking brake applications you need an adhesive that can both withstand the pressure and remain in place."

Metinoz says that design engineers throughout the supply chain will find the new adhesive of interest. "One auto manufacturer claims that in seven years all models will be equipped with EPB," she says. "Obtaining a brake shim adhesive solution to meet that demand is the concern of all engineers through the supply chain."
