Loctite EA 9460 Epoxy Adhesive is a commercial-grade, two-part modified epoxy formulation designed for high-performance structural bonding.
Engineered with non-sag slump resistance and a smooth paste consistency, Loctite EA 9460 provides superior peel strength coupled with exceptional shear strength. Its flexible cured matrix makes it ideal for joining dissimilar substrates—including metals, engineering thermoplastics, and sheet molding compound (SMC) thermoset laminates—without requiring surface primers.

Application & Dispensing Guidelines
For cartridge dispensing, load the 50ml cartridge into a compatible manual or pneumatic applicator. Remove the cap, purge a small amount of adhesive to ensure equal flow from both parts, and utilize a handheld dispenser gun. Extrude approximately 2.5 to 5.0 cm of waste paste before applying directly to clean, dry surfaces.
Clean up uncured excess adhesive prior to hardening using denatured alcohol or suitable solvent cleaner.
Frequently Asked Questions
1. What substrates can be bonded using Loctite EA 9460?
Loctite EA 9460 is specifically formulated for structural bonding of metals, engineering thermoplastics, and thermoset laminates (such as SMC). Its engineered flexibility accommodates thermal expansion differences when bonding dissimilar materials without requiring primers.
2. What is the cure time for Loctite EA 9460 at room temperature vs. heat cure?
At room temperature (25°C), Loctite EA 9460 reaches approximately 90% of its full cured properties within 24 hours, achieving full cure at 72 hours. Cure times can be significantly accelerated with heat (e.g., 6 to 8 hours at 149°C).
3. What are the storage requirements for Loctite EA 9460 epoxy?
Store unopened cartridges in a dry location at an optimal temperature between 8°C and 21°C (46°F to 69°F). Avoid storing below 8°C or above 28°C to maintain full shelf-life and mechanical properties.
4. Is Loctite EA 9460 suitable for severe environmental or automotive exposure?
Yes, cured Loctite EA 9460 offers excellent resistance to automotive fluids, impact shock, and structural fatigue, making it suitable for automotive, marine, and industrial equipment applications.
