ARALDITE 420 A/B Two-Part Epoxy Structural Adhesive High Strength Tough Paste Glue for Metal Honeycomb Composite GRP SMC

ARALDITE 420 A/B Two-Part Epoxy Structural Adhesive

ARALDITE 420 A/B is a high-strength, toughened two-component epoxy paste adhesive engineered for demanding structural bonding applications. Its exceptional toughness and peel resistance make it the preferred choice for bonding metals, honeycomb panels, and advanced composite structures in aerospace, automotive, and industrial sectors.

Key Features

• Outstanding toughness with high peel, impact, and cleavage resistance
• High tensile and shear strength for reliable structural integrity
• Excellent adhesion to metals, composites, GRP, and SMC without primers
• Paste consistency for controlled application and good gap-filling
• Room temperature cure; post-cure elevates thermal performance
• Proven in aerospace and transport structural applications

Compatible Substrates

• Metal (aluminium, steel, titanium, stainless steel)
• Honeycomb Panels (aluminium, Nomex)
• Carbon Fibre & Advanced Composites
• GRP (Glass Reinforced Plastic)
• SMC (Sheet Moulding Compound)

Typical Applications

Aerospace structural assembly, automotive body panel bonding, honeycomb sandwich panel fabrication, marine composite construction, railway carriage assembly, and high-performance industrial bonding requiring maximum toughness.
