Hysol EA 9695Henkel CorporationAerospace GroupPage 2 of 4Curing - This product may be cured for 1 - 1 ½ hours @ 250°F/121°C or for 1 - 2 hours @ 350°F/177°C.Heat up rate to the cure temperature is not critical, but should be between 1° and 10°F (0.6° and 5.6°C) perminute. Pressure should be applied before heating the parts to be bonded and maintained until cool down ofthe assembly.Cleanup - It is important to remove excess adhesive from the part and bonding tools before it hardens.Once the adhesive is cured, it is difficult to remove except by mechanical abrasion. Uncured adhesive may beremoved with denatured alcohol and many common industrial solvents. Be careful to prevent any solventfrom entering the uncured bondline as solvent will degrade the final bond performance. Consult with yoursupplier's information pertaining to the safe and proper use of solvents.Bond Strength PerformanceTensile Lap Shear StrengthTensile lap shear strength tested per ASTM D1002.
