Description
EP30 series compounds contain no solvents or diluents and are 100 % reactive. They cure in 24–48 hours at room temperature or 2–3 hours at 66–93 °C, and the cured material has 80–90 Shore D and a dielectric strength of about 17 kV/mm. EP30 with an A viscosity of 400–900 mPa·s is mixed 4:1, works from −51 to +121 °C and has a refractive index of 1.57. EP30-2 is mixed 10:1, withstands 4 K to +149 °C, meets ASTM E595 and has a dielectric constant of 3.00 at 9.375 GHz. Grade EP30HT-LO raises the limit to +204 °C. EP30NS with silica nanoparticles has a CTE of 25–30·10⁻⁶ 1/°C and abrasion resistance to ASTM D4060, while EP30QF with quartz has 20–25·10⁻⁶ 1/°C. The systems passed 1000 hours at 85 °C and 85 % humidity.
How to choose
For basic tasks at −51…+121 °C take EP30 with a 4:1 ratio. If cryogenic temperatures or microwave assemblies are involved, choose EP30-2, and for optics heated up to +204 °C, EP30HT-LO. Assemblies with strict thermal expansion requirements call for EP30NS and EP30QF, the latter being suitable for potting and casting. Separate two-component series exist for 1:1 mixing.

FAQ
What is the mix ratio of EP30 and EP30-2?
EP30 is mixed 4:1 by weight and EP30-2 10:1, where dosing accuracy is not critical.
What is the temperature range of EP30-2?
From 4 K to +149 °C. The compound meets ASTM E595 and has a dielectric constant of 3.00 at 9.375 GHz.
How long does EP30 take to cure at room temperature?
24–48 hours, and at 66–93 °C it is accelerated to 2–3 hours. A night at room temperature followed by a warm-up is recommended.
Which EP30 grade has a low CTE?
EP30NS (25–30·10⁻⁶ 1/°C) and EP30QF (20–25·10⁻⁶ 1/°C). The first is abrasion-resistant to ASTM D4060.
