PLEXUS MA8105

Main features

  • Primerless Multi-Material Bonding
  • Easy 1:1 Mixing
  • Low-Odor Non-Filled Formulation

Product Description

Plexus MA8105 Methacrylate Structural Adhesive is a direct-to-metal, two-part methacrylate structural adhesive for industrial and transportation assemblies. The 1:1 system supports primerless bonding to raw and coated metals, including galvanized steel, and also bonds thermoplastics, polyamides such as nylon, and composites. Its low-odor, non-filled formulation is paired with high strength, high elongation, toughness, and fatigue resistance for dissimilar-material joints. MA8105 cures tack-free and is suited to multi-material assembly where reducing primer steps and using a simple equal-ratio mix can streamline the bonding process.

Key features

  • Primerless metal adhesion: The adhesive bonds raw, coated, and galvanized metals without a separate primer step.
  • Broad material coverage: Supported substrates include polyamides, other thermoplastics, and composites.
  • Equal-ratio processing: The 1:1 two-part system simplifies proportioning and cures to a tack-free surface.

Applications / Suitable for

  • Industrial and transportation assemblies using raw or coated metals, galvanized steel, polyamides, other thermoplastics, or composites.

Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
