Description
EP46HT-1 for high-strength bonding works from −73 to +316 °C, has a Tg of 230–240 °C, a viscosity of 15 000–35 000 mPa·s and a dielectric strength of about 17.7 kV/mm. Curing takes 2–3 hours at 121–149 °C with a post-cure of 2 hours at 177–204 °C. EP125 is a paste for temperatures up to +316 °C with a Tg of 190–200 °C and a shear strength of 17.2–18.6 MPa; it cures in 3–4 hours at 149 °C or 2–3 hours at 177 °C and meets ASTM E595. Supreme 45HTQ, a toughened quartz-filled 100:30 epoxy, has a modulus of 3.4–3.8 GPa, a range of −51…+232 °C and a schedule of 2 hours at 149 °C and 4–6 hours at 177 °C. Supreme 46HT-2 works from −73 to +260 °C, has a T-peel above 10 pli and cures in 3–4 hours at 121–149 °C. All systems are hard, 80–95 Shore D, and resistant to chemicals and thermal cycling.
How to choose
The highest limit, +316 °C, belongs to EP46HT-1 and EP125; EP125 is a paste, while EP46HT-1 is thinner, 15 000–35 000 mPa·s. For +260 °C and good peel strength take Supreme 46HT-2, and for +232 °C with a quartz filler and a modulus of 3.4–3.8 GPa Supreme 45HTQ. All need an oven, so check whether the part will withstand heating to 149–204 °C. Assemblies that must cure without an oven are handled by other series.
