PLEXUS MA590
Harmonization Code : 3904.61.00.00 | Polytetrafluoroethylene plates / sheets / film / tape / strip, self-adhesive, in rolls
Main features
- 90-105 Minute Working Time
- Up to 38.1 mm Gap Fill
- >130% Typical Elongation
Product Description
Plexus MA590 Methacrylate Structural Adhesive provides an extended-working-time 1:1 methacrylate system for structural bonding of large composite, thermoplastic, and metal assemblies. Its 90-105 minute working time supports prolonged positioning, while the highly thixotropic consistency maintains a gap-filling bead. Typical values include a maximum gap fill of 1.5 in (38.1 mm), tensile strength of 1,880-2,750 psi, and elongation above 130%. This combination is relevant to large structures where parts must be aligned over a longer period while retaining a non-sag adhesive bead and a high-toughness cured joint.
Key features
- Long positioning window: A 90-105 minute working time supports extended assembly of large structures.
- High-build gap filling: The thixotropic 1:1 system supports a maximum gap fill of 1.5 in (38.1 mm).
- Highly extensible bondline: Typical elongation exceeds 130%, with tensile strength of 1,880-2,750 psi.
Applications / Suitable for
- Large composite, thermoplastic, and metal assemblies that require a long working window.
