Castor Oil-Based Polyurethane/Epoxy Intercross-linked Polymer Network Adhesives for Metal Substrates

Castor oil based polyurethane (CO-PU) was first synthesized from castor oil and 4, 4'-diphenyl-methane-diisocyanate (MDI). Then, a series of CO-PU/epoxy (EP) intercross-linked polymer network (ICPN) adhesives for metal substrates were prepared by a sequential method. The functional groups, tack -free time, mechanical properties, adhesive...

Thermal Properties of Fe-octacarboxyl Acid Phthalocyanine/Polyurethane Blends

The thermal stability of PU has been a critical factor to influence its applications as engineering materials. In this paper, the thermal properties of Fe-octacarboxyl acid phthalocyanine (Fe-OCAP)/polyurethane (PU) blends were investigated. The glass transition temperatures (Tg) of Fe-OCAP/PU blends were analyzed by differential scanning...
