Product Description
LOCTITE® EA 9432NA, also known as Hysol® Adhesive 9432NA, is an aluminum-filled, one-component epoxy adhesive supplied as a gray, thixotropic, non-sag paste. The mix-free formulation can be pumped and dispensed onto parts, then thermally cured at 250 to 300°F. It is formulated for tensile shear strength across a broad temperature range and can bond oily or otherwise poorly prepared surfaces, while clean, dry, properly prepared surfaces remain recommended. Tested substrates include aluminum, cold-rolled steel, fiberglass SMC, and fiberglass vinyl ester laminate.
Key features
- One-component processing: No mixing is required before application.
- Controlled dispensing: Typical viscosity is 150,000 to 300,000 cP with thixotropic, non-sag behavior.
- Thermal cure options: Cure for 60 minutes at 250°F or 30 minutes at 300°F.
- Temperature-dependent shear performance: Typical tensile shear on etched aluminum is 3,800 psi at 77°F and 3,000 psi at 250°F after a 30-minute cure at 300°F.
- Surface-condition tolerance: Typical shear on oily cold-rolled steel is 2,600 psi at 77°F after a 30-minute cure at 300°F.
Suitable for
- Bonding aluminum and cold-rolled steel parts.
- Bonding fiberglass SMC and fiberglass vinyl ester laminate components.
- Heat-cured assembly processes requiring pumpable, non-sag adhesive placement.

Application and Cure
Use controlled surface preparation, adhesive placement, clamping, and thermal cure to develop the bonded joint. Cure time depends on part geometry, substrate materials, bondline thickness, and oven efficiency.
Ideally store unopened containers at 2 to 8°C (36 to 46°F) in a cool, dry location. Allow refrigerated packages to return to room temperature before use. Keep containers tightly closed, protect them from direct sunlight, heat, sparks, and flame, and do not return unused material to the original container. Do not use in pure oxygen or oxygen-rich systems or as a sealant for chlorine or other strong oxidizing materials. Contact technical service for product-specific shelf-life information.
Cured Material Properties
