Araldite® 2015 Structural Adhesive: A Reliable Solution for Multi-Material Bonding

Product Overview

Araldite® 2015 is a two-component toughened epoxy structural adhesive that cures at room temperature to form a resilient bond. Its thixotropic nature allows application on vertical or overhead surfaces with gap-filling capability up to 10mm, and low shrinkage after curing. It is particularly suitable for bonding GRP, SMC, and dissimilar substrates, widely used in automotive, aerospace, marine, and industrial equipment sectors.

Key Advantages

• High Toughness & Peel Resistance: Toughened formulation offers excellent impact and peel resistance (23 pli roller peel strength), ideal for dynamic load applications.
• Multi-Substrate Compatibility: High bond strength on metals (aluminum, steel, copper) and plastics (GRP, CFRP, SMC, ABS), with aluminum-aluminum lap shear strength reaching 2408 psi.
• Environmental Resistance: Retains over 80% strength after 90-day immersion in gasoline, lubricating oil, or acetic acid; recovers to 94% strength after 90-day tropical exposure.
• Broad Temperature Range: Short-term heat resistance up to 158°C, with stable performance under thermal cycling (-30°C to +70°C).
• Ease of Application: 1:1 mix ratio (by volume/weight), applicable via dual-cartridge systems with static mixers.

Typical Application Cases

Usage Guidelines

• Surface Preparation: Degrease with isopropanol; metals should be sandblasted or chemically etched, plastics lightly abraded.
• Mixing & Application: Mix A/B components 1:1 by weight or volume. Pot life is 30-40 minutes at 25°C for 100g batch.
• Curing Conditions: Full strength achieved in 7 days at 23°C; accelerated curing via 40°C/16h or 80°C/1h.
• Safety: Wear gloves and goggles during application. Uncured residue removable with hot water and soap; cured residue requires mechanical removal.

Technical Assurance

Huntsman lab data shows Araldite 2015’s lap shear strength increases to 3292 psi after 90-day heat aging at 158°C, confirming long-term thermal stability. The product has a 3-year shelf life when stored at 2-40°C in sealed containers, complying with ISO 4587, ISO 4578, and other international standards.
