LOCTITE EA 9360 / 9359.3 / 9330 / 9309 / 9380 / 9364FR AERO (Hysol) toughened epoxy pastes with high peel strength

Country: · Model: EA 9360 / 9359.3 / 9330 / 9309 / 9380 / 9364FR AERO

EA 9360 is a two-part toughened epoxy paste for structural bonding of metals, honeycombs and composites where high peel strength is needed. Shear is 34.5 MPa at 25 °C, and shear strength is retained at 107–121 °C. The pastes are used in the production and repair of airframes, interiors and engine units.

EA 9360: 2K toughened paste; A:B = 100:43 by weight (2:1 by volume); pot life 50 min (200 g); cure 5–7 days at 25 °C or 1 h at 82 °C; operating temperature > 107 °C
EA 9360 shear: 27.6 MPa at −55 °C; 34.5 MPa at 25 °C; 20.7 MPa at 82 °C; 13.8 MPa at 107 °C
EA 9360 peel: Bell Peel up to 303 N/25 mm; T-Peel 218 N/25 mm
EA 9360 resistance: after 1000 h at 70 °C and 85 % RH, MIL-H-5606 hydraulic fluid, JP8 — retains 39–43 MPa at 24 °C

Description

The mixing ratio is 100:43 by weight or 2:1 by volume, supplied in dual cartridges. The pot life of a 200 g mass is 50 minutes at 25 °C, and cure is 5–7 days at 25 °C with handling strength after 24 hours, or 1 hour at 82 °C. On 2024-T3 aluminum per ASTM D1002 shear is 27.6 MPa at −55 °C, 34.5 MPa at 25 °C, 20.7 MPa at 82 °C and 13.8 MPa at 107 °C. With BR-127 primer the strength is about 40.7 MPa at 24 °C and remains 39–43 MPa after 1000 hours at 70 °C and 85 % humidity, and also after MIL-H-5606, JP8 and de-icing fluid. Bell Peel reaches 303 N/25 mm, T-Peel 218 N/25 mm, and the resin has tensile strength 42.4 MPa, elongation 5 % and thermal conductivity 0.25 W/(m·K).

How to choose

This class includes EA 9359.3 (easy mixing in 2:1 cartridges), EA 9330 and 9330.3 (tolerate variations in bondline thickness), EA 9309, 9309.2 and 9309.3NA, EA 9380 and 9380.05 for low-temperature cure, and also EA 9345, 9363, 934NA, 9392 and 9320NA. For interiors there is the flame-retardant EA 9364FR free of halogens, antimony and phenol, and the sheet MA 562SFR.
