LOCTITE EA 9309.3NA AERO - HEATCON

1 technical Process BulletinLOCTITE EA AEROE poxy Paste Adhesive(KNOWN AS Hysol EA )1 of 5 INTRODUCTIONLOCTITE EA aero is a toughened two-part paste adhesive. It contains 5 mm glass beadsfor bondline thickness control. LOCTITE EA aero bonds metal skins and honeycomb core to yieldtough permanently flexible joints resistant to humidity, water and most common fluids. Its outstanding feature ishigh shear and peel strength to High Shear Strengthx High Peel Strengthx Bondline Thickness Controlx Good Environmental ResistanceUncured Adhesive PropertiesPart APart BColorPink-redBlueViscosity @ 77 F1500-3,800 PoiseBrookfield ViscometerHBT 7 @ 20 rpmLVF Spdl 1 @ 60 rpmViscosity @ 25 C150-300 Pa Pa sBrookfield ViscometerHBT Spdl 7 @ rad/s LVF Spdl 1 @ rad/sDensity (g/ml)

2 Life @ <77 F/25 C1 year1 yearThis material will normally be shipped at ambient conditions, which will not alter our standard warranty,provided that the material is placed into its intended storage upon receipt. Premium shipment is available - This product requires mixing two components together just prior to application to the parts to bebonded. Complete mixing is necessary. The temperature of the separate components prior to mixing is notcritical, but should be close to room temperature (77 F/25 C).

3 Mix RatioPart APart BBy Weight10022 Note: Volume measurement is not recommended for structural applications unless special precautions aretaken to assure proper Life (450 gram mass) 35 minutes @ 77 F/25 CMethod - ASTM D2471 in water Process BulletinLOCTITE EA AEROE poxy Paste Adhesive(KNOWN AS Hysol EA )2 of 5 ApplicationMixing - Combine Part A and Part B in the correct ratio and mix thoroughly. THIS IS IMPORTANT! Heatbuildup during or after mixing is normal. Do not mix quantities greater than 450 grams as dangerous heatbuildup can occur causing uncontrolled decomposition of the mixed adhesive.

4 TOXIC FUMES CAN OCCUR,RESULTING IN PERSONAL INJURY. Mixing smaller quantities will minimize the heat - Bonding surfaces should be clean, dry and properly prepared. For optimum surface preparationconsult the LOCTITE Surface Preparation Guide. The bonded parts should be held in contact until theadhesive is set. Handling strength for this adhesive will occur in 12 hours @ 77 F/25 C, after which thesupport tooling or pressure used during cure may be removed. Since full bond strength has not yet beenattained, load application should be small at this - This adhesive may be cured for 3 to 5 days @ 77 F/25 C or 1 hour @ 180 F/82 C to achieve - It is important to remove excess adhesive from the work area and application equipment before ithardens.
