HETRON FR 650 Series Flame Retardant Resins
HETRON FR 650 Series resins are flame retardant polyester resins. Composites made with HETRON
FR 650 Series resins have been tested and have achieved a Class 1 Flame Spread per ASTM E-84
without addition of synergists such as antimony trioxide.
HETRON FR 650 Series resins may be classified as a high strength resin per the definition in section
63.5935 of the US RCP MACT (Title 40 CFR Part 63 Subpart WWWW).
HETRON FR 650 T-20 resin is a low viscosity, promoted, thixotropic, version. It exhibits excellent wet-out
properties and low drainage when applied to vertical surfaces. This resin is formulated to contain 35%
styrene.
HETRON FR 650 INF-20 resin is a low viscosity promoted resin optimized for the infusion process. This
grade may also be used for resin transfer molding. It exhibits excellent glass wet out properties.
APPLICATIONS AND HETRON FR 650 Series resins, depending on the grade selected, can be used in hand lay-up, spray-up,
USE filament winding and infused flame retardant applications. Markets include architectural, mass transit,
passenger rail, electrical and mine ducting.
MODAR 820 series resins may be considered where low smoke properties are desired. DERAKANE 500
series fire retardant epoxy vinyl ester resins may be considered when improved corrosion resistance is
desired. Recommendations for specific services and environments can be provided by contacting us at
