Description

Araldite M CAS NO 37350-55-3 is a high-performance, one-component, heat-curing epoxy resin adhesive system. This product is engineered to deliver exceptional bond strength, chemical resistance, and durability for demanding industrial applications. It is essential for manufacturers and fabricators in the aerospace, automotive, electronics, and composite bonding sectors who require reliable, high-strength structural adhesives for critical assemblies.

Application

• Aerospace Component Assembly: Bonding of honeycomb panels, composite structures, and metal fittings where high strength-to-weight ratio and fatigue resistance are critical.
• Automotive Structural Bonding: Used in the assembly of body panels, chassis components, and for bonding dissimilar materials like metals to composites.
• Electronics Potting and Encapsulation: Provides protection for sensitive electronic components from moisture, vibration, and chemical exposure.
• Industrial Tooling and Molding: Fabrication of durable molds, jigs, and fixtures that require dimensional stability and resistance to wear.
• Wind Turbine Blade Manufacturing: Structural bonding of composite blade sections and root joints, offering long-term durability in harsh environmental conditions.
• Marine and Transportation: Bonding and sealing applications in boat building, rail, and heavy vehicle manufacturing.

Quality Control

Our Araldite M is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including viscosity, epoxy equivalent weight (EEW), gel time, and cured mechanical properties. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed, original container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Do not freeze. Keep away from heat sources and open flame. Shelf life is typically 12 months from the date of manufacture when stored under these recommended conditions.
