Abstract
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.
