1. Product Overview

Araldite® 2015-1 is a two-component, room temperature curing epoxy paste adhesive. It is thixotropic, toughened, and non-sagging up to 10 mm thickness, providing resilient bonds. It is specifically formulated for GRP, SMC, and dissimilar material bonding, with good resistance to weathering and environmental exposure.


2. Applications

  • Bonding glass-reinforced plastics (GRP) and sheet moulding compounds (SMC).

  • Suitable for metal-to-metal and plastic-to-plastic joints.

  • Useful in applications requiring gap filling, structural resilience, and durability under weathering conditions.

  • Applicable in transportation, construction, marine, and industrial sectors where toughened bonds are essential.
