A Phenolic Resin for Prepreg Composites With an Ultra-Low Free Formaldehyde Content

Hexion introduces a new phenolic resin for prepreg composites with an ultra-low free formaldehyde (ULEF) content of less than 0.1%.

The new, lower volatile organic compound (VOC) CelloBond J 6021X01 resins, specifically designed for prepreg manufacturing, maintain the CelloBond product line’s proven excellence in fire, smoke and toxicity (FST) performance while providing improved safe use and handling. The ULEF resin systems have 90% less free formaldehyde than previous systems. This new system results in reduced emissions during composite manufacturing and allows the development of prepreg composite systems with even further reductions in free formaldehyde content. “Prepreg” refers to a composite made by saturating, or pre-impregnating, a reinforcing fabric with the resin system before, rather than during, molding.
