When it comes to picking an adhesive, especially for structural applications, it is important that you choose the right product. There are a lot of adhesives available with similar properties, specs, and chemical makeups, so determining which adhesive is right for your needs can be a challenge.
At Gluegun.com, we have been in the adhesives industry for over fifty years and worked with a diverse range of products. Our adhesive experts are sharing their honest thoughts about Plexus MA420 and Infinity Bond MMA 420 as well as how these two similar products compare.
Plexus MA420
Plexus is a popular brand of high-performance adhesives developed by ITW Performance Polymers. These products can be used in a wide range of applications but are often tied to industrial uses. They tend to be known for their durability and performance, but they can be more expensive.
The ITW Plexus MA420 (AO420) is a two-part methacrylate adhesive that is commonly used in structural bonding applications. It is designed to bond various materials including different types of metals, thermoplastics, and composites. Along with its high strength, the Plexus MA420 adhesive has good fatigue resistance and great elongation so it can hold up in many harsh bonding environments.
Infinity Bond MMA 420
While Plexus is very well known, Infinity Bond is more like a well-kept secret. The brand has a large collection of adhesive products including several structural adhesives similar in nature to the Plexus line. They are known for their high-quality, yet affordable adhesive options.
The Infinity Bond MMA 420 adhesive is a good, low-cost alternative to Plexus MA420. Like the Plexus MA420 adhesive glue, it is a high-strength, two-part adhesive that is commonly used for structural bonding applications involving metals, plastics, and composites. It also has great impact resistant, shock resistance, and flexibility.
Comparing Plexus MA420 vs. Infinity Bond MMA 420
At first glance, Plexus MA420 and Infinity Bond MMA 420 are very similar in nature. They can be used for a lot of the same applications and have many overlapping properties. While they are so similar, they also have a few key differences. We are comparing Plexus MA420 and Infinity Bond MMA 420 to help you determine which one is the best fit for your needs.
Handling Strength Time
One difference between Plexus MA420 and Infinity Bond MMA 420 is the handling strength time or the amount of time it takes for the adhesive to form a bond strong enough to stay intact so you can start handling the substrates. While both have a fast set time of about five minutes, the handling strength time varies between the two products. The Plexus MA420 structural adhesive has a handling strength time of 18 to 22 minutes. The Infinity Bond product has a handling strength time closer to 15 minutes. While a subtle discrepancy, this difference could be important. A faster handling strength could increase your production speed.
Shelf Life
Shelf life can be important for companies that use a lot of product and want to ensure they always have enough product on hand. The shelf life of the Plexus MA420 glue is around 10 months (7 months for the black color) when stored as recommended. Infinity Bond MMA 420 has a slightly long shelf life of closer to 12 months in the right conditions.
Product Options
From cartridges to pails, adhesives come in various packaging sizes to meet different application needs. The Plexus MA420 adhesive glue can be found in 490-mL cartridges, 5-gallon pails, and 50-gallon drums. The adhesive also comes in black, blue, and amber. Like Plexus MA420, Infinity Bond MMA 420 comes in 490-mL cartridges, 5-gallon pails, and 50-gallon drums but also has a 50-mL cartridge option for businesses needing a smaller amount such as for small applications or to test the product. The adhesive comes in a cream or black color.
Price
Perhaps the biggest difference between the Plexus MA420 adhesive and the Infinity Bond product is the price. Because Plexus is so well known, its products tend to be at the higher end of prices. On the other hand, Infinity Bond prides itself on being the affordable option without having to compromise on quality. They have numerous Plexus adhesive alternatives for businesses not wanting to break the bank.
