Product Description
ARALDITE® AV 170 is a thixotropic, single-component epoxy structural adhesive supplied as a paste for heat-cured bonding. It is recommended for a wide range of metals, temperature-resistant plastics and composites, with railway carriage identified as a product end use. The adhesive cures at 140–180°C, fills gaps up to 3 mm, and contains spacers that maintain a minimum 0.05 mm bondline; a 0.05–0.10 mm adhesive layer is recommended for greatest lap shear under the stated process. Published data include specified lap shear above 20 MPa at 80°C, very good peel strength, good chemical resistance and heat resistance to 120°C. The one-component format removes component mixing, while the thixotropic rheology supports controlled placement before assembly and clamping.
Key features
- One-component thixotropic paste: Applies directly without component mixing and supports controlled placement on prepared joint surfaces.
- Gap and bondline control: Fills gaps up to 3 mm and contains spacers that maintain a minimum 0.05 mm adhesive layer.
- Heat-cured structural performance: Cures at 140–180°C, is heat resistant to 120°C, and has specified lap shear strength above 20 MPa at 80°C.
Applications / Suitable for
- Railway carriage bonding and assembly
- Structural bonding of a wide variety of metal substrates
- Bonding temperature-resistant plastics and composite materials
