STRUCTURAL ADHESIVES AND PREPARATION METHODS THEREOF
摘要:
The disclosure relates to structural adhesive compositions containing decarboxylated rosin acid (“DCR”), methods of preparation, and applications thereof. The structural adhesive can be one-component or two-component compositions, selected from epoxy-based adhesives, acrylic-based adhesives, polyurethane-based adhesives, and silyl modified polymer-based adhesives. The DCR has a Kb value of 25-90, a density of 0.9 to 1.0 g/cm3 at 20° C., a viscosity of 15 to 60 cSt at 40° C., and an acid value of
