PLEXUS MA2045 | Krayden

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.
