Loctite EA 615 HYSOL EPXI-PATCH Blue Structural Epoxy Adhesive – 90.8g for Aerospace Repair
Loctite EA 615 HYSOL EPXI-PATCH is a blue, two-component structural epoxy adhesive from Henkel’s premium HYSOL aerospace adhesive range, specifically designed for structural bonding, composite patching, and repair applications in aerospace and defense environments. The EPXI-PATCH designation indicates a formulation optimized for patch repair operations — providing the gap-filling, adhesion, and structural performance needed for effective structural repair of damaged aircraft components.
The distinctive blue color of EA 615 aids visual inspection of adhesive coverage during patch bonding operations — the blue adhesive contrasts clearly with most aircraft substrate colors including aluminum, composite, and primer-coated surfaces, making it easy to confirm complete bondline coverage before closure and final assembly. This coverage visibility is particularly important in structural repair operations where inadequate adhesive coverage can compromise the structural integrity of the repair.
The 90.8g kit provides a practical quantity for aerospace repair operations — larger than small syringe kits for adequate coverage of patch areas, but smaller than large production quantities that would result in material waste for single-repair MRO applications.

Technical Information
Loctite EA 615 HYSOL is based on Henkel’s advanced HYSOL aerospace epoxy platform, using a high-performance bisphenol epoxy resin cured with a hardener system optimized for structural repair applications. The HYSOL formulation provides excellent gap-filling properties — the adhesive can fill irregular surface gaps and voids in repair areas without sagging, maintaining the adhesive in the correct bondline thickness range for effective structural repair performance.
The blue pigment system provides consistent, stable color throughout the mixed and cured adhesive, maintaining its inspection-friendly appearance from application through final cure. The pigmentation does not interfere with the curing chemistry or reduce the mechanical or chemical resistance properties of the cured HYSOL epoxy network.
For structural repair applications, surface preparation of the repair area is critical for achieving the required bond strength to restore structural integrity. The damaged area should be cleaned, properly shaped to define the repair geometry, and the bonding surfaces prepared per the applicable structural repair manual (SRM) or engineering disposition. EA 615 should be mixed per Henkel’s TDS and applied within the specified pot life for consistent results.
