Description

Syntactic pastes and films consist of an epoxy matrix with microspheres, so they give strength at low density, resistance to vibration, impact and thermal stresses, and electrical insulation. After cure they are machined and drilled, the pastes can be dispensed by robot, and flame-retardant and halogen-free (REACh) variants exist. EA 9321 is a two-part thixotropic gray paste with a long open time, in 25 g E-Z PAK pouches, cartridges and Clip Pack. The 9396.6 MD paste has 41.7 MPa compression, 2 hours of pot life, cures at 25 °C and is stored for 12 months at −18 °C. EA 9814, 9820 and 9825 are one-part, up to 177 °C, and 9814 is flame-retardant.

How to choose

For repair take EA 9321 with its long open time. When a lighter part is needed, choose 9396.6 MD. For honeycomb parts working at 177 °C, EA 9814, 9820 and 9825 are suitable. The range also includes EA 9807 and SynSkin HC 3056.
