Vibration Damping Adhesives |
| 摘要 |
Adhesive compositions are described which are useful for damping vibration associated with hard disk drives. The adhesive compositions include a combination of at least two partially immiscible acrylic copolymers such that the compositions exhibit at least two distinct glass transition temperatures. Also described are label assemblies utilizing such adhesives and related methods of use. |

1. A multiphase domain acrylic pressure sensitive adhesive exhibiting a high temperature peak damping functionality, the adhesive exhibiting (i) a loss factor greater than 1.2 at a temperature of at least 100° F. (37.8° C.); and (ii) a shear modulus greater than 150 psi;
the adhesive comprising at least two copolymers which are at least partially immiscible relative to one another, the adhesive exhibiting at least two distinct glass transition temperatures (Tg's), each corresponding to a respective copolymer; and 0.1 to 10 wt % acrylic acid. |
