PLEXUS MA2090
Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- Highly Thixotropic Vertical-Bead Control
- 90-95 Minute Work Time
- 0.75-38 mm Non-Sag Gap Filling
Product Description
Plexus MA2090 is a highly thixotropic two-part 10:1 methacrylate structural adhesive for composite, thermoplastic and metal assemblies. The non-sagging formulation resists bead sag and slide on vertical surfaces. At 23.9 deg C, typical work time is 90-95 minutes, supporting large assemblies that require extended positioning time. The adhesive fills gaps from 0.75 to 38 mm. After cure, typical tensile strength is 15.2-20.0 MPa, elongation at break is 90-120%, and aluminum lap-shear strength is 12.4 MPa.
Key features
- Highly thixotropic vertical-bead control: The formulation is designed to resist adhesive sag and slide on vertical surfaces.
- 90-95 minute work time: Typical work time is 90-95 minutes at 23.9 deg C.
- Non-sag gap filling to 38 mm: The adhesive is specified for gaps from 0.75 to 38 mm.
Applications
Structural bonding of composites, thermoplastics and metals; vertical bonding; large-bead assemblies requiring extended working time.
