Infinity Bond MMA 420 is a perfect "jack-of-all-trades" Methyl Methacrylate Adhesive (MMA). It offers a fast set time (right around 5 minutes) making it a great adhesive for high volume product assembly, smaller parts, or jobs you want to get done fast. MMA 420 offers strong, permanent bonds to difficult surfaces like metals, plastics, composites, and more.

Each cartridge comes with 2 static mixing nozzles for efficient dispensing.

Like all of the Infinity Bond MMA adhesives, MMA 420 has great impact and weather resistance and requires little to no surface preparation. MMA 420 has a work time of around 4 - 6 minutes and reaches handling strength in about 15 - 20 minutes. Once fully cured, MMA 420 provides a strong, flexible bond that excels even under extreme hot or cold temperature ranges.
