MODAR 820 series resins are comprised of a novel resin composition designed for architectural and
mass transit applications. Fire retardant laminates(1) made with MODAR 820 series resins and
filled with alumina trihydrate (ATH) have met ASTM E-84 class 1 flame spread index requirements
and exhibit low smoke characteristics typically required by building codes. These same
compositions additionally meet mass transit requirements as measured by ASTM E662 and E162.
MODAR 820 series resins readily accept high filler loadings without substantial loss of its cured
mechanical properties. Mixes made with MODAR 820 TC resin exhibit exceptional suspension
stability. MODAR 820 INF resin is recommended where higher filler loadings are required.
