OMICURE® U 35 M N

OMICURE® U 35M N is a cycloaliphatic substituted urea used as a latent ACCELERATOR for the dicyandiamide curing of epoxy resins. It enables shelf-stable one-part epoxy/dicy formulations that cure faster or at lower temperatures. OMICURE® U-35 N provides the longest room temperature shelf life among CVC substituted ureas. The micronized version is OMICURE® U-35M N. While less efficient than aromatic ureas by weight, it achieves cures in about one hour at 115°C and under seven minutes at temperatures of 150°C or higher. Suggested use levels are up to 5 phr, with cure times depending on formulation and application.
