Epoxy resin system rises from the flames

A new nonhalogenated epoxy resin system called EP21HTFR-1 offers outstanding flame resistance and minimal smoke generation, even on prolonged exposure to open flames.

Master Bond has developed a new nonhalogenated epoxy resin system called EP21HTFR-1, which offers outstanding flame resistance and minimal smoke generation, even on prolonged exposure to open flames.

Based on new proprietary in-house technology Master Bond EP21HTFR-1 is a two component epoxy resin system with a user friendly one to one mix ratio.

It cures readily at ambient or more quickly at elevated temperatures and has a service capability up to 200C.

Unlike other commercially available flame retardant compounds, it does not emit any halogens as well as other noxious and/or toxic vapours even when subjected to open flames for prolonged time periods.

In addition the EP21HTFR-1 is UL94V0 pending.

Master Bond polymer system EP21HTFR-1 is designed for bonding, sealing and casting applications and can be applied by all conventional methods.

A lower viscosity version called EP21HTFR-1LV is available to facilitate casting uses.

The cured EP21HTFR-1 exhibits remarkably high physical strength properties as well as superior resistance to mechanical shock and vibration.

Electrical insulation properties are excellent.

Master Bond EP21HTFR-1 has superior chemical resistance to water, salt solutions, fuels and many other organic as well as inorganic chemicals even after long exposure periods.

The service temperature range is an impressive -50 to +200C.

EP21HTFR-1's flame resistant capability to withstand exposure to open flames with minimal smoke and/or generation of noxious and/or toxic gases makes it the preferred choice for critical aerospace, electronic and industrial assemblies where the flammability potential in service must be minimised and product safety is a primary consideration.
