Corrosion Resistant Epoxy Vinyl Ester Resins and Fire Retardant Resins

Ashland is a leading supplier of corrosion resistant resins for reinforced plastics. We offer the most comprehensive line of corrosion resistant, heat resistant and fire retardant resins on the market today. Ashland’s experience spans five decades.

No Single FRP Resin Can Handle Every Kind of Corrosion Problem


That´s why Ashland has made a wide range of famous HETRON® corrosion resistant epoxy vinyl ester resins to fit all customers’ needs. HETRON epoxy vinyl ester resins differ from polyesters due to their enhanced mechanical properties. HETRON resins offer excellent physical strength and improved impact and thermal shock resistance compared to regular polyester resins. HETRON epoxy vinyl ester resins are also available as low styrene content (<35%) versions.

Maximum Corrosion Resistance with HETRON Resins

HETRON epoxy vinyl ester resins offer maximum corrosion and temperature resistance to acids, alkalis, hypochlorites and many solvents. HETRON corrosion resistant products have been formulated by using the F-Cat technology (see pages 16-17) for flexibility in production. The HETRON resin technical service group provides recommendations and specific services at hetron@ashland.com.

HETRON Fire Retardant Resins


Ashland´s range of HETRON fire retardant resins is the broadest in the industry. You can find HETRON resins with or without halogens incorporated into the polymer backbone. HETRON fire retardant resins can be based on epoxy vinyl ester or unsaturated polyester technology. Due to their excellent fire retardant properties, HETRON resins have been successfully used in building and construction (wall cladding, panels, roofing, shower cabins), in infrastructure (panels, electrical boxes, bus shelters, street lamps), in transport (interior and exterior parts in trains, buses, trams, subways) and in marine (rescue boats, patrol vessels, luxury cruiser interior parts). 

The HETRON resin family includes products tested according to both national (NF, DIN, BS, UNE, etc.) and international (EU, UL, IMO, etc.) classification requirements.
