  • Polyurethane adhesive with chemical resistant
    Patent number: 11629273
    Abstract: There is provided a pressure sensitive adhesive composition comprising a polyurethane polymer that comprises the reaction product of a polyisocyanate component and a polyol component. The polyol component has a hydrophilic-lipophilic balance (HLB) less than 10. The polyurethane further comprises 0.5 to 10 wt.-% of hydrophilic polymerized units having an HLB greater than 12, such as a reaction product of a polyethylene glycol polymer. In another embodiment, the polyurethane further comprises pendent ethylenically unsaturated groups. Also described are articles such as laminating tapes and protective films as well as methods of bonding substrates with the pressure sensitive adhesive and laminating tape.
