EPOLOCK 6900: Aluminum-Filled Epoxy Adhesive for Metal Repair & Molding
Overview
EPOLOCK 6900 is a high-performance, two-component epoxy adhesive reinforced with aluminum particles, designed for repairing cracks, fractures, and defects in aluminum bushings, castings, and metal parts. Its liquid formulation ensures excellent flow for molding and bonding applications, while providing robust mechanical strength and chemical resistance.
Key Features
✔ Aluminum-Filled Formula: Enhances structural integrity and thermal conductivity.
✔ High Shear Strength: 17–18 MPa (steel-to-steel, ASTM D1002).
✔ Heat Resistance: Withstands up to 80°C (post-cured at 100°C, ASTM D648).
✔ Chemical Resistance: Resists oils, hydrocarbons, and diluted acids/alkalis (up to 5%).
✔ Machinable After Curing: Allows for precision finishing.
✔ Long Shelf Life: 2 years when stored at 25°C in sealed containers.
Applications
- Repairing Defects: Cracks/fractures in aluminum parts, bushings, and castings.
- Metal Bonding: Structural adhesion for industrial equipment.
- Molding & Casting: Liquid flow ideal for filling gaps and complex shapes.
- Surface Restoration: Rebuilds worn or corroded metal surfaces.
