SUPRASEC® 2004 is a member of the Liquid Pure MDI isocyanate family. These products have been modified to remain liquid at ambient temperatures. SUPRASEC 2004 MDI Isocyanate is a modified diphenylmethane diisocyanate with a clear to slightly hazy appearance. This product is designed as an alternative to difunctional products such as pure 4,4 MDI or materials containing elevated levels of 2,4 MDI. When used as a precursor for a prepolymer, the resulting material may experience a slightly different performance with an identical B-Side resin. As a result, formulations may need minor adjustments to meet the end requirements.
