Plexus MA530: High-Performance Structural Methacrylate Adhesive for
Large Composite and Metal Assemblies
Plexus MA530 is a two-part methacrylate structural adhesive
designed for bonding thermoplastics, metals, and composites. It is
mixed at a 1:1 volume ratio, appears gray when mixed, offers a
working time of 30-40 minutes at room temperature, and cures to
form a high-strength, tough bond.

Product Introduction
This product is designed for use on large structures where a
moderate open time is needed. It offers excellent gap tolerance,
fatigue endurance, outstanding impact resistance, and superior
toughness, making it ideal for bonding small to large composite and
metal assemblies. Plexus MA530 is available in ready-to-use 400-ml
cartridges, 5-gallon pails, or 50-gallon drums, and is dispensed as
a non-sagging gel.
Special Attributes
Beyond its excellent mechanical properties, Plexus MA530 emits very
low volatile organic compounds (VOCs) during cure (<0.5%) and
provides good resistance to hydrocarbons, acids, bases, and salt
solutions. Its cure rate is significantly affected by temperature,
and it should be applied within the recommended temperature range
for optimal performance.
Application Scenarios
Plexus MA530 is widely used in fields such as transportation,
construction, wind energy, shipbuilding, and industrial equipment.
Specific application scenarios include: bonding body panels and
frames of buses and rail vehicles, assembling truck cabins,
installing exterior wall panels (such as aluminum composite
panels), bonding components of wind turbine blades, and adhering
decks and superstructures of yachts and ships. Its excellent
toughness and fatigue resistance make it particularly suitable for
structures subjected to dynamic loads and vibrations.
