Advances in Polyurea RIM for Automotive Applications

Polyurea RIM, because of its production speed, internal release characteristics, high temperature dimensional stability and increased resistance to water absorption, has arrived at the forefront of RIM technology as a better route to producing automotive body panels. In this paper we will discuss the use of inexpensive fillers, in particular, sized wollastonite, in polyurea body panels. In addition, a new polyetherpolyamine for body panel applications will be discussed. We also studied the effect of postcure conditions on high temperature stability of body panel formulations.
