Plexus MA530 MMA Adhesive 400 ml – White

Description

Plexus MA530 is a high-performance, two-part methacrylate adhesive designed for structural bonding of composites, coated metals, thermoplastics, and raw metals using PC120 primer.

Engineered for large assemblies that require a moderate working time, MA530 delivers outstanding toughness, excellent elongation, and strong resistance to fatigue, impact, and vibration. Its 1:1 mix ratio, smooth dispensing, and gap-filling thixotropic formula make it a preferred choice for fabrication, transportation, marine, and architectural panel bonding.

Key Features and Benefits

• Moderate 30–40 minute working time for large assemblies

• High strength structural bonding across composites, metals, and plastics

• Very high elongation for exceptional toughness under dynamic loads

• Excellent gap filling and thixotropic viscosity for vertical surfaces

• Fast fixture time to accelerate assembly workflows

• 1:1 mix ratio for easy dispensing and setup

• Strong performance on coated metals, including powder-coat and e-coat

• Bonds many difficult substrates including DCPD, FRP, gelcoat, ABS, PC, PVC, TPUs, and more

Common Applications

• Composite panel bonding for marine hulls, decks, and structures

• Transportation assemblies such as truck, trailer, and specialty vehicle components

• Architectural and façade panels, signage, and exterior cladding

• General industrial fabrication requiring high impact resistance and durability

• Bonding dissimilar materials where flexibility and toughness are critical
