ARALDITE AW 4858/ Hardener HW 4858 is a two-component room temperature curing black coloured epoxy adhesive paste of high strength and toughness. Performances can be enhanced by post-curing at elevated temperature. It is suitable for bonding a wide variety of metals, and especially designed for bonding composites.
FEATURES:
- Very high lap shear and peel strength
- Bonds a wide variety of materials (metal, composite and thermoplastics)
- Good moisture resistance
- Extremly tough and resilient adhesive
- Long pot life, ideal for large composite part assemblies
APPLICATIONS:
- Automotive
- Ideal for big CFRP parts assembly (open time > 60 min)
- Ideal for dissimilar substrates bonding
