- 33.8 MPa Aluminum Lap Shear
Product Description
LOCTITE EA 9330.3 AERO is a two-component, room-temperature-curing epoxy paste adhesive formulated with thixotropic, low-slump handling and high peel strength. The 100:33 Part A-to-Part B weight mix provides a 60-minute pot life for a 100 g mass at 25°C. The mixed adhesive is gray with a density of 1.14 g/mL. It reaches handling strength after 24 hours at temperatures above 25°C and develops normal performance after 5–7 days, with an alternative 1-hour cure at 82°C for small masses. Typical testing on phosphoric-acid-anodized 2024-T3 AlClad aluminum demonstrates tensile lap shear and peel performance across subzero, ambient, and elevated temperatures.
Key features
- Low-slump thixotropic paste: Supports controlled placement before cure without converting the rheology description into a drip- or void-prevention claim.
- Defined mix and working window: Mix Part A and Part B at 100:33 by weight; typical pot life is 60 minutes at 25°C for a 100 g mass.
- Room-temperature or accelerated cure: Normal performance develops after 5–7 days above 25°C; a 1-hour cure at 82°C may be used for small mixed masses.
- Prepared-aluminum lap shear performance: Typical tensile lap shear is 33.8 MPa at 25°C after a 5-day room-temperature cure on phosphoric-acid-anodized 2024-T3 AlClad aluminum.
- Peel performance: Typical floating roller peel is 414 N/25 mm at 25°C after a 5-day room-temperature cure under the stated test conditions.

Processing and Cure
Bring the separate components close to room temperature, then combine and mix completely at the specified weight ratio. Do not mix quantities greater than 250 g because heat buildup can cause uncontrolled decomposition and toxic fumes. Apply the adhesive to clean, dry, properly prepared bonding surfaces and hold the parts in contact until set. Remove uncured excess before it hardens; denatured alcohol and many common industrial solvents may be suitable when used in accordance with the solvent supplier’s safety instructions.
Keep each component tightly closed in a cool, well-ventilated area away from incompatible materials. Warranty life is 1 year for both Part A and Part B when stored below 25°C. Do not heat Part B above 100°C. Use adequate ventilation, avoid skin and eye contact, and follow current product labeling and safety documentation before use.
