PLEXUS MA2045
Harmonization Code : 3904.61.00.00 | Polytetrafluoroethylene plates / sheets / film / tape / strip, self-adhesive, in rolls
Main features
- Extended 45-50 Minute Work Window
- Vertical Non-Sag Placement
- Deep 38 mm Gap Bonding
Product Description
Plexus MA2045 is a two-part, 10:1 methacrylate adhesive for structural bonding of composite, thermoplastic, and metal assemblies where thick joints or vertical placement are required. The non-sagging formulation has a 45-50 minute work time at 75 deg F (23.9 deg C) and a typical gap tolerance of 0.75-38 mm. It is formulated to limit sag and slide on vertical surfaces and to avoid boiling in gaps up to 38 mm. Typical cured properties include 15.2-20.0 MPa tensile strength and 90-125% elongation.
Key features
- 0.75-38 mm Thick-Gap Bonding: Accommodates unusually deep structural joints.
- 45-50 Minute Work Window: Provides extended positioning time at 75 deg F (23.9 deg C).
- Vertical Non-Sag Application: Limits sag and slide during placement on vertical surfaces.
Applications
Applications include structural bonding of composites, thermoplastics, and metals, including vertical-surface and thick-gap assemblies.
