Reinforced Isocyanurate/Oxazolidone Polymers for Structural Composites Application

A new liquid injection system suitable for molding by RIM, RTM and cast techniques is discussed. This material which is based upon an oxazolidone/urethane modified polyisocyanurate is characterized by its ultra low viscosity, low reaction exotherms and a controllable cure time, thus making it ideal for making large and complex structural parts, particularly those requiring high levels of reinforcement.
