Product Description
ARALDITE 2012 is a rapid-curing, two-component epoxy adhesive for structural and multipurpose bonding at room temperature. The high-viscosity system mixes 1:1 by weight or volume and provides a four-minute pot life for fast assembly work. It develops high shear and peel strength with a tough, resilient cured bond and is suitable for joining metals, ceramics, glass, rubbers, rigid plastics, and other common materials. Application guidance recommends clean, dry, properly prepared surfaces, a 0.05–0.10 mm adhesive layer, prompt assembly, and even contact pressure. At 23°C, typical lap shear strength exceeds 1 N/mm² after 20 minutes and 10 N/mm² after 61 minutes under the stated test method.
Key features
- Rapid strength development: Four-minute pot life with typical lap shear strength above 1 N/mm² after 20 minutes at 23°C.
- Tough structural bond: Documented high shear and peel strength with a tough, resilient cured adhesive.
- Multi-material bonding: Suitable for metals, ceramics, glass, rubbers, rigid plastics, and other commonly used materials.
Applications / Suitable for
- Metal-to-metal assembly and repair bonding
- Glass and ceramic component bonding
- Rubber and rigid-plastic bonding in industrial and workshop applications
