Liquid moisture curable polyurethane adhesives for lamination and assembly |
| 摘要 |
This invention relates to polyurethane prepolymer containing adhesives that are liquid at room temperature and that do not phase separate under typical storage and use conditions and that can be cured by exposure to moisture or active hydrogen-containing curing agents. The polyurethane prepolymer adhesives exhibit surprisingly good adhesion to plastics such as fiberglass reinforced plastics (“FRP”). |

1. A liquid polyurethane prepolymer adhesive composition comprising a reaction product obtained by reacting a stoichiometric excess of polymeric MDI with polyether polyol; at least one liquid paraffinic oil; and at least one aromatic oil different from the paraffinic oil, wherein the liquid paraffinic oil and the aromatic oil are present in a by weight ratio of 2:1 to 1:2, and wherein the polyurethane prepolymer adhesive is moisture curable, and in liquid form at 25° C. and free of solvent. |
