Epoxy resin bonds and seals up to 400 deg F

A nonhalogenated epoxy resin system featuers outstanding flame resistance and minimal smoke generation for bonding, sealing and casting for service up to 400 deg F.

A nonhalogenated epoxy resin system featuers outstanding flame resistance and minimal smoke generation for bonding, sealing and casting for service up to 400 deg F.

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

Based upon 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 400 deg F.

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

In addition the EP21HTFR-1 is UL 94V.0 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 -65 deg F to +400 deg F.

EP21HTFR-1s 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 minimized and product safety is a primary consideration.
