MMA Adhesive Dispensing system
MMA Adhesive Dispensing Systems for Industrial Bonding
At Dispense Robotics, we provide cutting-edge adhesive dispensing equipment designed for high-performance materials like Methyl Methacrylate Adhesives (MMAs). These two-component structural adhesives are trusted across industries for their strength, flexibility, and fast-curing capabilities. Whether you're bonding metal, plastic, or composite parts, our automated dispensing systems ensure precision, repeatability, and speed on every application.
What Are MMA Adhesives?
Methyl Methacrylate Adhesives (MMAs) are 2K acrylic adhesives made by combining a resin (based on methyl methacrylate monomer) and a peroxide-based hardener. When mixed, they rapidly cure at room temperature through an exothermic reaction, forming a tough, chemically resistant bond. Compared to epoxy or polyurethane adhesives, MMAs offer faster curing, better flexibility, and superior performance on dissimilar materials.
Why Choose MMA Adhesives for Industrial Bonding?
MMA structural adhesives are ideal for bonding metals, plastics, fiberglass, and composites—even when those materials expand or flex at different rates. With high impact resistance, minimal surface prep, and outstanding fatigue performance, MMAs are often used to replace welding, mechanical fasteners, and traditional glues.
Top Features of Methyl Methacrylate Adhesives
- High tensile, peel, and shear strength
- Cures at room temperature — no ovens or heat required
- Fast fixture times (3–15 minutes)
- Bonds metals, plastics, fiberglass, and composites
- Fills large gaps — up to 10 mm
- Outstanding flexibility and impact resistance
- Excellent chemical, solvent, and weather resistance
- High tolerance for mixing ratio deviations
- Works well in dynamic or high-vibration assemblies
