Reinforcement Optimization in High Temperature Polyurea Body Panel Material

Polyurea RRIM offers a proven technology for proposed vertical body panel programs. Applications to this point in time have involved non-standard assembly procedures, but polyurea RRIM is a viable candidate for programs involving an “E-coat” or “ELPO” step. The selection of a reinforcement is crucial to the overall performance of the composite. Physical properties are specified by the particular program, and they can be achieved by the correct selection of reinforcement level and type. The greater emphasis that has recently been placed on surface quality can also be satisfied through the proper reinforcement selection. Lastly, the interaction of the polyurea RRIM composite with an environment which leads to an absorption of moisture may be controlled by choosing a reinforcement that will allow a high diffusion rate and subsequently a higher maximum use temperature.
