Abstract
A pressure sensitive adhesive tape that employs a water-absorptive backing, a microparticle-containing pressure sensitive adhesive and a water-dispersible component is provided. A method of bonding close fitting parts is also disclosed. In the method, a microparticle-containing pressure sensitive adhesive tape (with or without the water-dispersible component in the adhesive) is employed. Articles made using the tape and/or by the method are also disclosed.
Claims18
A microparticle-containing pressure sensitive adhesive tape comprising a water-absorbing backing having first and second opposed surfaces, and a first microparticle-containing pressure sensitive adhesive surface on at least a portion of the first surface of the backing wherein said first microparticle-containing pressure sensitive adhesive surface comprises:
- a) from about 90 to 99.75 parts by weight of a microparticle-containing component;
- and correspondingly
- b) from about 10 to 0.25 parts by weight of a water-dispersible component;
- which first microparticle-containing pressure sensitive adhesive surface forms an essentially permanent bond to a substrate when said first surface is wetted with water, applied to said substrate, and dried.
A microparticle-containing pressure sensitive adhesive tape comprising n water-absorbing backing having first and second opposed surfaces, and a first microparticle-containing pressure sensitive adhesive surface on at least a portion of the first surface of the backing wherein said first microparticle-containing pressure sensitive adhesive surface comprises:
- a) from about 90 to 99.75 parts by weight of a microparticle-containing component;
- and correspondingly
- b) from about 10 to about 0.25 parts by weight of a water-dispersible component.
