When evaluating an adhesive, it is important to consider the adhesive’s specifications and performance. Especially when it comes to structural bonding, you need an adhesive that matches your application and is effective.

With over fifty years in the adhesives industry, our team has worked with numerous structural adhesives from different brands in various applications. In this guide, we narrow in on Infinity Bond MMA 300 and the updated MMA 300 Plus, including how they work, their differences, whether they are effective, and when to use them.

Infinity Bond MMA 300 Product Details

The Infinity Bond MMA 300 is a high-performance, two-part methyl methacrylate adhesive that is commonly used to bond a wide range of substrates, including metal, composites, and most plastics. The adhesive has a 1:1 mix ratio and cures quickly at room temperature with a faster working time.

The Infinity Bond MMA 300 adhesive offers a strong resistance to impact, shock, and temperature fluctuations, making it well-suited for bonds exposed to movement or thermo cycling. Like other methyl methacrylates, the Infinity Bond MMA 300 glue also has good chemical resistance and can tolerate surface contamination better than other structural adhesives, so it requires minimal surface preparation.

Some other key product specifications of the original Infinity Bond MMA 300 adhesive are listed below.

You can buy Infinity Bond MMA 300 in 50ml and 400ml cartridges as well as 5-gallon pails and 55-gallon drums for high-volume applications. View the Infinity Bond MMA 300 technical datasheet (TDS) for more product details.

What About Infinity Bond MMA 300 Plus?

While Infinity Bond MMA 300 is the original formula, Infinity Bond MMA 300 Plus is an updated version of the adhesive designed to provide improved performance for durable bonding applications.

Some notable differences between the Infinity Bond MMA 300 original formula and the Infinity Bond MMA 300 Plus adhesive are related to the cure times. The new Plus formula has a working time of around 5 to 8 minutes and a fixture time of about 10 to 12 minutes compared to 3 to 6 minutes and 10 to 15 minutes, respectively. The 400 ml cartridge of Infinity Bond MMA 300 Plus also uses F-system mixing nozzles, while the original cartridge uses C-system nozzles.

Otherwise, both products offer good impact resistance, chemical resistance, and temperature resistance. They also have comparable strength, durability, and substrate compatibility. We recommend testing the new MMA 300 Plus formula.

Is Infinity Bond MMA 300 Effective? Our Review

Yes. After review and testing, our team believes that both the Infinity Bond MMA 300 methyl methacrylate and the MMA 300 Plus are great adhesives for structural bonding applications with compatible bonding requirements. They can be an especially effective solution when you are dealing with dissimilar materials or demanding environments. The faster cure time and minimal surface preparation requirements also make it an attractive choice for higher speed production lines where manufacturers are looking for limited downtime during assembly.

Another aspect we love about the Infinity Bond MMA 300 adhesives is the price. While the Infinity Bond brand may not be as well-known, the Infinity Bond MMA 300 products are comparable in performance and offer a potential cost-saving alternative to Plexus® MA300, Araldite® 2021, ASI MP 55300, LORD® 201/19, and more, depending on the specifics of the application.

While great for many applications, it is important to note that the Infinity Bond MMA 300 MMA adhesives are not compatible with low surface-energy plastics like PP or PE. Like most MMAs, the adhesives also have a strong odor and do not have as high an ultimate strength as most epoxy adhesives.

Ideal Applications

Because of their strength and versatility, the Infinity Bond MMA 300 and MMA 300 Plus adhesives are used across a wide range of industries. They are particularly valuable when bonding dissimilar materials or when speed is critical.

Below are some of the more common applications where the IB MMA 300 adhesives perform well:

• Metal to plastic bonding in enclosures and housings
• Fiberglass and composite panel assembly
• Automotive and transportation components
• HVAC systems and ductwork assemblies
• Marine and outdoor equipment
• General industrial repair and maintenance

These applications benefit from the adhesive’s ability to handle stress, movement, and environmental exposure, but this is not an all-inclusive list. If you have questions about whether an Infinity Bond MMA 300 formula is right for your specific application, you can talk with our adhesive experts.

Is Infinity Bond MMA 300 Right for You?

While the Infinity Bond MMA 300 adhesives are great for many applications, is it right for yours? Our team breaks down some factors to consider when determining if Infinity Bond MMA 300 or 300 Plus is compatible with your application.

1. Identify your substrates
   These adhesives perform best on metals, composites, and plastics such as ABS, PVC, and acrylic. It is not ideal for polyethylene or polypropylene.
2. Consider your production speed
   If you need a fast fixture time, these adhesives may be a good choice.
3. Evaluate environmental exposure
   These adhesive handles vibration, impact, and temperature cycling well, so they are suitable for industrial and outdoor use.
4. Review your surface prep capabilities
   If your process cannot support extensive cleaning or abrasion, MMA adhesives offer a distinct advantage over epoxies.
5. Check your gap requirements
   The MMA 300 formulas can fill larger gaps than many structural adhesives. This capability is especially helpful for uneven bonding surfaces.

Try a Sample

Choosing the right structural adhesive can significantly impact your production efficiency and long-term performance. The Infinity Bond MMA 300 adhesives deliver reliable structural bonding performance across a wide range of materials and conditions but may not be right for every application.

If you are considering Infinity Bond MMA 300 or MMA 300 Plus, the best next step is to test it in your application. You can buy a sample of Infinity Bond MMA 300 and MMA 300 Plus to try on your own. You can also speak with our team, and they can suggest an adhesive for your specific needs.
