Description

The base paste EA 9394 is qualified to MMM-A-132 Rev B Type I Class 3 Form 3 Group 1 and by many OEMs, has low toxicity and long pot life. The mixing ratio is 100:17 by weight, and the mixed viscosity is about 160 Pa·s. The pot life of a 450 g mass is 90 minutes at 25 °C, and more than 450 g must not be mixed because of dangerous heating. Cure takes 3–5 days at 25 °C with handling strength after 24 hours, or 1 hour at 66 °C for small masses. The cured resin has tensile strength 46.0 MPa, modulus 4237 MPa, compression 68.9 MPa, Shore D hardness 88 and a dry Tg of 78 °C.

How to choose

The choice depends on the cure schedule and the filler. EA 9394S comes in Semkit cartridges with reduced thixotropy, EA 9394.2 cures fast, EA 9394/C-2 is hot cure with a high operating temperature, and EA 9395 has a non-metallic filler. For wet layup and composite repair, take the low-viscosity resins EA 9396, EA 9390 (high strength in hot wet condition) and EA 956 with an open time of up to 8 hours.
