PLEXUS MA300/3000

Main features

Simple 1:1 Meter-Mix Processing
Fast 3-6 Minute Assembly
High-Strength Stiff Cured Bond

Product Description

Plexus MA300 pairs a two-part, 1:1 methacrylate system with structural bonding of thermoplastics, metals, and composites. At 74 deg F (23 deg C), the non-sagging adhesive provides a 3-6 minute work time, reaches 500 psi (3.4 MPa) in 11-13 minutes, and reaches 1,000 psi (6.9 MPa) in 13-16 minutes. Typical cured tensile strength is 24.2-29.6 MPa with 20-40% elongation and 78 Shore D hardness. Applications include supported ABS, acrylic, FRP, gelcoat, PVC, steel, aluminum, polyester, styrenic, urethane, and vinyl-ester assemblies.

Key features

Simple 1:1 Mixing: Uses equal component volumes for cartridge or meter-mix dispensing.
3-6 Minute Work Window: Supports rapid assembly at 74 deg F (23 deg C).
24.2-29.6 MPa Tensile Strength: Provides a high-strength cured methacrylate bond.

Applications

Applications include structural bonding of supported thermoplastics, metals, and composites, including ABS, acrylic, FRP, gelcoat, PVC, steel, aluminum, polyesters, styrenics, urethanes, and vinyl esters.
