Polysiloxane-grafted copolymer pressure sensitive adhesive composition and sheet materials coated therewith. |
摘要 |
<p>This invention provides pressure sensitive adhesive (PSA) compositions comprising a copolymer having a vinyl polymeric backbone having grafted thereto polysiloxane moieties. The compositions may contain other ingredients such as tackifier and/or plasticizer. An exposed surface of the PSA composition is initially positionable on a substrate to which it will be adhered but, once adhered, builds adhesion to form a strong bond. The PSA compositions may be used alone or in blends with unsiliconized PSA compositions. The invention also provides sheet materials coated with the PSA composition such as tape, labels, etc.</p> |
