Solidium MR/NAF is an interior panel able to resist periodic moisture exposure while maintaining dimensional stability and reduced thickness swell 30-50% better than untreated MDF panels. And with formaldehyde emission levels more than 3 times lower than CARB Phase 2 standards, Solidium MR/NAF is a smart choice for cabinets, fixtures, and decorative applications in homes, schools, hospitals and other projects in which improved indoor air quality and green building credits are a priority. Solidium MR/NAF delivers the best of both worlds to help you create ideal environments, year after year.
