Does Infinity Bond MMA 420 Actually Work? Our Team’s Review
While the IB MMA 420 has a lot of beneficial properties that sound great, does it really work? And how does it stand up against other comparable MMAs? Our team takes a closer look at the strengths and weaknesses of Infinity Bond MMA 420, as well as how it compares to some popular name-brand adhesives.
Strengths
Upon further review of the Infinity Bond MMA 420 glue, our team believes some of the most important strengths of the MMA 420 adhesive are:
- A quick cure time for fast and high-volume production
- A toughened formula with good flexibility
- High impact and shock resistance
- Minimal surface preparation requirements
- The ability to bond to different substrates
- A lower cost compared to comparable name-brand products
Limitations
While the adhesive has numerous beneficial properties, the product isn’t without its limitations, including:
- A cure time that is too fast for large assemblies

- Not as high a shear strength as some other structural adhesives
Vs. Plexus® MA420 (AO420)
One comparable product on the market is Plexus MA420. The two adhesives have similar formulations and properties. The biggest difference tends to be price. The Plexus MA420 is a popular name-brand option that can come at a steep price. On the other hand, the Infinity Bond MMA 420 adhesive glue is a high-quality product that is not as well-known, but it tends to be more affordable.
