In industrial manufacturing and assembly, choosing the right adhesive is critical to achieving long-lasting and durable bonds. Especially if you are working with challenging substrates, you need an adhesive you can trust.
Our team of adhesive experts is taking a closer look at Infinity Bond MMA 500, a methyl methacrylate (MMA) adhesive designed for commercial applications where other adhesives may fall short.
About the MMA 500 Adhesive
Infinity Bond MMA 500 is a two-part methyl methacrylate (MMA) adhesive that comes in a 1:1 ratio and is designed for high-strength structural bonding. It has a shear strength of 1300 psi, a working time of around four to five minutes, and a temperature range from -60°F to 250°F. Unlike many other adhesives, it can bond low surface energy plastics. The MMA 500 glue can be dispensed with a manual or automated dispensing system.
Some other key product information for the Infinity Bond MMA 500 adhesive includes:
-
Impact resistant
-
Ability to withstand extreme temperature fluctuations
-
Room temperature cure
-
Excellent adhesive to metals, thermosets, thermoplastics, and ceramics
-
6-month shelf life
Unique Properties of the Infinity Bond MMA 500
While there are many MMAs, a thorough review of the Infinity Bond MMA 500 shows it does have some properties that make it stand out.
Low Surface Energy Bonding
Perhaps the biggest differentiator between the MMA 500 adhesive and other MMAs is its ability to bond to low-energy and difficult plastics like polypropylene and polyethylene. These low surface energy plastics present a challenge for many products as they repel the adhesive and make it more difficult for the adhesive to wet out the surface. Consequently, many adhesives require primers or extensive surface preparation to form a lasting bond.
Instead, the MMA 500 is a specialized adhesive that is designed to permeate the surface of these low-energy substrates and bond to them without extensive surface preparation.
Fast Curing
Time is money in industrial settings. The MMA 500 methylacrylate adhesive has a fast working time of around four to five minutes. This work time allows components to be handled sooner and supports faster production cycle times without sacrificing bond quality. This balance makes the IB MMA 500 a practical choice for higher volume operations.
While this fast cure time is often a plus, it can also make the MMA 500 unsuitable for certain applications. Operators do not have a lot of time to reposition components during assembly. Bonding large surface areas can also present a challenge as the adhesive could set too quickly.
Price
Because specialty adhesives are needed to bond low-energy substrates without extensive surface preparation, these products usually come at a higher cost. After reviewing Infinity Bond MMA 500, we discovered that it is a cost-effective and high-quality alternative to similar products from higher-priced brands that often include a premium markup for brand recognition.
Ideal Applications
Ideal applications for Infinity Bond MMA 500 include industrial bonds where strong, reliable adhesion to low-energy substrates is critical. Below are some of the most common applications for the MMA 500 adhesive.
Automotive Assembly- Ideal for bonding plastic components like interior panels and trim pieces
Aerospace Manufacturing- Suitable for plastic parts in aircraft interiors or assemblies, where weight reduction and reliability are priorities
Consumer Electronics- Used for enclosures and components made from low-energy plastics to save manufacturers time and labor on extensive surface preparation
Construction- Can bond panels, beams, and structural components where mechanical fasteners are not preferred
While versatile, MMA 500 is not ideal for every application. Review the technical datasheet or consult an adhesive expert to ensure it is the best fit for your application. Testing can also confirm that the product performs effectively in your specific environment before deploying it across your production line.
Final Thoughts
After review, the Infinity Bond MMA 500 is a cost-effective, high-quality solution for bonding low-energy plastics. It minimizes the need for substantial surface preparation, and with its faster cure time, it can be a good choice for higher speed production lines. If you would like to try it out on your application, you can order a sample of the Infinity Bond MMA 500 to test.
