PLEXUS MA8120
Harmonization Code : 3904.61.00.00 | Polytetrafluoroethylene plates / sheets / film / tape / strip, self-adhesive, in rolls
Main features
- Low-Halogen Primerless System
- Broad Coated-Metal Adhesion
- Salt-Spray Environmental Resistance
Product Description
Plexus MA8120 Methacrylate Structural Adhesive pairs a low-halogen, two-part methacrylate system with direct bonding of metal, plastic, and composite assemblies. The 1:1 formulation provides primerless adhesion to raw and coated metals, including hot-dip galvanized surfaces, as well as most thermoplastics and composites. Its lower-odor formulation combines high strength and elongation with fatigue resistance, impact resistance, and toughness. Environmental resistance includes salt-spray exposure and related environmental factors. MA8120 is suited to industrial and transportation structures that require broad substrate coverage without a separate metal-primer step.
Key features
- Low-halogen formulation: The two-part adhesive is positioned for direct-to-metal structural assembly.
- Primerless substrate range: It bonds raw and coated metals, thermoplastics, and composites without a separate metal primer.
- Durable cured behavior: High strength and elongation are combined with fatigue, impact, and environmental resistance.
Applications / Suitable for
- Industrial and transportation structural assemblies using raw or coated metals, thermoplastics, or composites.
