Flame Resistant Epoxy for Potting/Encapsulation

Two component, room temperature curing epoxy potting/encapsulation system EP21FRNS-2 is flame retardant per the UL94V.0 standard. It has a convenient 1 to1 mix ratio, produces very low smoke levels and features a non-halogen filler. EP21FRNS-2 has high physical strength properties and is serviceable from -50°C to 90°C per the UL 94V.0 specification. It offers superior electrical insulation properties and has a dielectric constant of 4.5 at 60 Hz. Resistance to chemicals, moisture and thermal cycling is outstanding.

Master Bond EP21FRNS-2

Master Bond EP21FRNS-2 has high bond strength to metals, ceramic, glass and most plastics. To optimize its properties the best cure schedule is overnight at room temperature, followed by 2-3 hours at 150-200°F. Working life for a 100 gram mass is 90-150 minutes at 75°F. EP21FRNS-2 has a flowable viscosity – ideal for potting and encapsulation.
