Description
ARALDITE® 2019 structural adhesive is a two-component, epoxy adhesive paste of high strength and toughness. Performances can be enhanced by post-curing at elevated temperatures. It has been designed to perfectly bond onto composites, especially CFRP, but it is suitable for bonding a wide variety of metals, ceramics, and many other substrates in common use.
Features
- Very high lap shear
- Bonds a wide variety of materials (metal, composite and thermoplastics)
- Temperature resistant up to 284°F (140°C)
- Extremely tough and resilient adhesive
- Contains spacers to ensure a minimum bond line thickness of 0.05 mm
