Key Features

• 90–105 Minute Working Time – Extended open time gives installers substantially more time to dispense, position, and assemble large components.

• 1:1 Mix Ratio – Simple equal-volume two-component mixing.

• 400mL Dual Cartridge Format – Ready for use with compatible 400mL 1:1 dispensers and static mixers.

• Excellent Gap Filling – Handles bond gaps from approximately 0.03" to 1.50" (0.75–38 mm).

• Non-Sagging Gel – Thick consistency helps the adhesive stay where it is applied.

• High Impact Resistance & Fatigue Endurance – Designed for demanding structural assemblies exposed to vibration, movement, and repeated loading.

• High Elongation – Greater than 130% strain to failure helps create tough, resilient bonds.

• Marine-Oriented Formulation – Developed for large composite and fiberglass marine structures.

• Chemical Resistant – Excellent resistance to hydrocarbons, salt solutions, and acids/bases within approximately pH 3–10.

• Wide Service Temperature Range – Approximately -40°F to 180°F (-40°C to 82°C).

Why Use MA590 for Large Marine Installations?

Many structural MMA adhesives cure relatively quickly. That can become difficult when installing or positioning large marine components because installers may need considerable time to apply adhesive across the complete bonding area before final assembly.

Plexus MA590 provides 90–105 minutes of working time at 74°F (23°C), allowing considerably more time for adhesive application and component positioning. The product was developed specifically with large marine structures in mind and is commonly used for bonding fiberglass boat stringers and liners.

This makes MA590 particularly attractive for installation jobs where working time and positioning flexibility are more important than extremely fast fixture time.

Application Notes

For maximum bond performance, apply enough adhesive to completely fill the joint when the parts are assembled. Adhesive dispensing, component positioning, and fixturing should all be completed before the 90–105 minute working time expires.

Once positioned, the assembly should remain undisturbed until the specified fixture time has been reached. Application temperatures between approximately 65°F and 85°F (18°C–30°C) are recommended for consistent curing performance.

Chemical Resistance

MA590 offers excellent resistance to:

• Hydrocarbons

• Salt solutions

• Acids and bases between approximately pH 3–10

The adhesive is more susceptible to:

• Polar solvents

• Strong acids

• Strong bases

Safety & Handling

Plexus MA590 is a flammable methacrylate adhesive. Use only with adequate ventilation and keep the product away from heat, sparks, open flames, and other ignition sources. Wear appropriate gloves and eye protection during handling and application.

The supplied SDS identifies the adhesive for transportation as UN1133, Adhesives, Class 3, Packing Group II.
