Product Description
ARALDITE® 2081-10 is a fast-curing, two-part acrylic structural adhesive developed for bonding a range of plastics, composites and metals. The low-odour, non-flammable system provides a 10-minute open time and a 10-11 minute pot life for a 20 g mix at 25°C, supporting rapid assembly operations. The mixed adhesive is off-white and combines high strength with good flexibility. It can be dispensed from mixer-equipped cartridges or applied manually or robotically. Tested plastic substrates include ABS, PMMA, PVC and PC; polyolefins and other low-surface-energy materials are excluded. Proper cleaning and surface preparation remain important for durable bonds.
Key features
- Rapid strength development: 10-minute open time; on sandblasted aluminium at 23°C, typical lap shear exceeds 1 MPa in less than 20 minutes and 10 MPa in less than 23 minutes.
- Broad substrate range: Supports bonding of tested plastics, composites and metals; not intended for polyolefins or other low-surface-energy materials.
- Low-odour, non-flammable formulation: Two-part acrylic system with good flexibility and an off-white mixed appearance.
Applications / Suitable for
- Plastic bonding involving ABS, PMMA, PVC or PC.
- Composite bonding involving CFRP and epoxy-, polyester- or vinyl ester-based GRP.
- Metal and mixed-material assemblies involving aluminium, steel, stainless steel, copper or brass.

Store sealed components in their original containers at 2-8°C for up to 24 months. The product may be brought to room temperature before use, but cumulative room-temperature exposure should not exceed six months. Prolonged exposure above 25°C reduces shelf life. Follow the expiry date on the packaging and the applicable Safety Data Sheet for handling precautions.
