MATERIALS, ADHESIVES AND COATINGS
EP17HT, EP17HT-LO, EP17HTND-2, EP13 one-component hot-cure epoxies with Tg up to 210 °C (up to +316 °C)
Country: · Model: EP17HT, EP17HT-LO, EP17HTND-2, EP13
One-component epoxies of the EP17HT and EP13 series for assemblies with the highest operating temperatures among organic adhesives, up to +316 °C. They need no mixing, keep their pot life for a long time at room temperature and cure only in an oven. They are used in engine assemblies, high-temperature electronics and heating elements.

Description
EP17HT-LO has medium viscosity, 45 000–75 000 mPa·s, and cures for 4–6 hours at 149 °C with a hold of 12–24 hours at 177 °C. After that the Tg is 200–210 °C, the range −62…+316 °C, the shear strength 20.7–22.1 MPa, and ASTM E595 compliance is confirmed. EP17HTND-2 is a paste for vertical surfaces, with the same Tg and range, a schedule of 6–8 hours at 149 °C and 6–12 hours at 177 °C, and shear of 20–21.4 MPa. The EP17HT series includes EP17HTDA versions for die attach, electrically conductive ones and "snap-cure" versions. EP13 is a paste with heat resistance up to +260 °C, a shear strength of 24.1 MPa and a schedule of 60–90 minutes at 149–177 °C; EP13LTE with a reduced CTE also exists.
How to choose
For +316 °C and a Tg of 200–210 °C take EP17HT-LO in liquid form or EP17HTND-2 as a paste for vertical surfaces. If +260 °C is enough and a shear strength of 24.1 MPa is needed with a shorter schedule of 60–90 minutes, choose EP13. EP17HTDA exists for die attach, and EP13LTE for a reduced CTE. Such compounds also withstand parts that undergo soldering, sterilization or hot painting.

FAQ
What is the glass transition temperature of EP17HT-LO?
200–210 °C after a schedule of 4–6 hours at 149 °C and 12–24 hours at 177 °C. The operating range is −62…+316 °C.
Do EP17HT and EP13 need to be mixed?
No, both series are one-component and cure only in an oven. At room temperature the pot life is long.
What is the shear strength of EP13?
24.1 MPa with a schedule of 60–90 minutes at 149–177 °C. The operating temperature is up to +260 °C.
What is the viscosity of EP17HT-LO?
45 000–75 000 mPa·s, which is medium. The compound meets ASTM E595.
How does EP17HTND-2 differ from EP17HT-LO?
It is a paste for vertical surfaces with the same Tg and range. The schedule is different, 6–8 hours at 149 °C and 6–12 hours at 177 °C.
