RE-WORKABLE MOISTURE CURABLE HOT MELT ADHESIVE COMPOSITION METHODS OF USING THE SAME, AND ARTICLES INCLUDING THE SAME |
摘要 |
Disclosed is an article that includes a first substrate, a second substrate, and a re- workable adhesive composition, the first substrate being bonded to the second substrate through the adhesive composition. The adhesive composition is derived from a moisture curable polyurethane hot melt adhesive composition that includes a polyurethane prepolymer that includes the reaction product of a first crystalline polyester polyol having a number average molecular weight of from at least 5500 grams per mole (g/mol) to about 20,000 g/mol and a melting point of at least 40 °C, and a polyisocyanate. The re-workable adhesive composition is cleanly removable from at least one of the first substrate and the second substrate after conditioning the article at a temperature of from at l east 60 °C to no greater than 100 °C for a period of about 30 minutes. |
