What are MMA Adhesive?
Methyl Methacrylate (MMA) adhesives, commonly referred to as acrylic adhesives or structural adhesives, are a type of adhesive based on methyl methacrylate monomer, most commonly found in two component cartridges with separate chambers that are then mixed. Other formulations are also available, such as 'no-mix adhesives'.
The term "acrylic adhesives" is a broad classification as most adhesives are acrylic based.
Within the two part methacrylate adhesive, which consist of an adhesive resin and an activator, there are two main classifications based on the mixing ratio: MMA adhesives 10:1 and MMA adhesives 1:1.
The main differences are:
MMA Adhesive Parameter | 10:1 Mix Ratio | 1:1 Mix Ratio |
---|---|---|
Mixing Ratio | Requires 10 parts resin to 1 part activator | Requires equal parts of resin and activator |
Tensile Elongation | 50-150% | Typically Below 30% |
Tensile Strength | Lower (2,500-3,500 PSI) | Higher (3,500-3,750 PSI) |
Storage Stability at Elevated Temperatures (25-35°C)
|
High – More resistant to temperature variations |
Low –Susceptible to premature hardening |
Shelf Life | Longer (12 months) | Shorter (8-9 months) |
Mixing Precision | More precise due to defined mixing proportion | Easier to mix, but requires precise application |
Conclusion:
ADINOX 10:1 MMA adhesive or two-part methacrylate adhesive offers an ideal balance of tensile strength and elongation, making them suitable for a wide range of substrates and industries. Their superior chemical stability and extended shelf life make them a versatile bonding solution.
ADINOX 1:1 Mix Ratio MMA adhesive or two part methacrylate adhesive offer higher tensile strength, making them ideal for applications requiring rigid and strong bonds, but with less flexibility and shorter shelf life.
