Product Description
PLEXUS® MA8110 Methacrylate Adhesive is a two-part, 1:1 methacrylate structural adhesive for direct bonding to many metal substrates, including galvanized G60 and G90 steel, and for selected thermoplastic and composite assemblies. The gray, non-sag mixed adhesive provides a typical 9 to 11 minute working time at 23°C and supports gap-filling bondlines from 0.75 to 9.5 mm. It is documented for limited surface preparation on supported substrates and develops high tensile and lap-shear properties after cure.
Key features
- Direct-to-metal bonding: The adhesive is documented for primerless bonding to many metals, including galvanized G60 and G90 steel.
- 9 to 11-minute working time: The documented process window is measured at 23°C.
- Gap-filling cured bond: The adhesive supports 0.75 to 9.5 mm bondlines with typical tensile strength of 21.4 to 24.8 MPa.
Applications / Suitable for
- Structural bonding of galvanized and other metal assemblies
- Selected thermoplastic bonding
- Composite assembly bonding
