RIMLINE® Polyol / SUPRASEC® MDI

RIMLINE® Polyol / SUPRASEC® MDI are ideally processed on low-pressure metering equipment consisting of two material components and a flushing solvent. This low-viscosity system offers multiple advantages in the pultrusion process, including excellent wetting of reinforcements, fast reaction kinetics, and low pull forces while providing good surface quality at accelerated line speeds with minimal VOCs. Extended gel times of the Huntsman system allow for ease of start-up and system purge.
