Araldite® 2031-1 is a black, two-component, room-temperature curing epoxy paste adhesive. It is thixotropic and non-slumping up to 10 mm thickness. The system is toughened, resilient, and highly weather-resistant, with integrated spacers ensuring a minimum bond line of 0.05 mm. It is designed to provide durable bonding performance on metals, composites, and engineering plastics.
Bonding of metals (aluminium, steel, stainless steel, copper, brass, galvanised steel).
Bonding of composites (GRP, CFRP, SMC).
Adhesion to engineering plastics (ABS, PA, PC, PMMA, PVC).
Structural applications requiring toughness, peel resistance, and weathering stability.
Suitable for both manual application and bulk processing with metering/mixing equipment.
