Overview of Plexus MA2030 Adhesive Plexus MA2030 is a white two-part methacrylate adhesive that stands out for its exceptional UV and yellowing resistance. This adhesive is specifically designed for structural bonding of thermoplastics, metals, and composite assemblies, offering a practical working time of 30 minutes when mixed at a 10:1 ratio. It is particularly favored in the marine and transportation industries for its rapid-curing capabilities and the ability to effectively fill gaps ranging from 0.03 inches to 1.5 inches, depending on the laminate thickness and composition.Plexus MA2030 simplifies the bonding process with its requirement for minimal surface preparation, making it a top choice for applications demanding high durability and aesthetic consistency. The adhesive is noted for its excellent fatigue endurance, outstanding impact resistance, and superior toughness, ensuring reliable performance under challenging conditions. Available in a white hue that maintains its color integrity, Plexus MA2030 is conveniently packaged in ready-to-use 490-ml cartridges, facilitating easy and efficient application. Key Benefits of MA 2030 Extended Working Time: Offers a flexible working time range of 26-34 minutes. UV Stability and Aesthetic Consistency: White coloration remains stable and resists yellowing under UV exposure. Room Temperature Curing: Fast and consistent strength development at ambient conditions. High Thixotropy: Allows for the application of large, non-sag beads for versatile placement. Compatible Materials Composites: Effective on DCPD, FRP, Gelcoat, Phenolics, Epoxy Based Composites, RIM. Thermoplastics: Bonds well with ABS/ABS Blends, Acrylics, PBT, Polycarbonate, Rigid PVC, TPUs. Coated Metals: Suitable for Powder coated or E-coated Metals. Raw Metals: Bonds to PC120 treated Aluminum, Stainless Steel, Raw Steel, etc. Technical Specifications Property Specification Color White Mix Ratio 10:1 Shear Strength 1,600 – 2,100 psi (11.0 – 17.9 MPa) Adhesive Viscosity (Part A) 180,000 – 220,000 cP Activator Viscosity (Part B) 35,000 – 70,000 cP Minimum Working Time 26 minutes Maximum Working Time 34 minutes Minimum Fixture Time 70 minutes Maximum Fixture Time 90 minutes Minimum Tensile Strength 2,700 psi (18.6 MPa) Maximum Tensile Strength 3,200 psi (22.1 MPa) Tensile Elongation > 30%
