MMA 320 Toughened Impact Resistant MMA Adhesive Overview

Infinity Bond MMA 320 is a perfect "jack-of-all-trades" Methyl Methacrylate Adhesive (MMA). It offers a medium set time giving users time to set their parts and excellent strength to a huge range of substrates. MMA 320 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 320 has great impact and weather resistance and requires little to no surface preparation. MMA 320 has a work time of around 13 - 17 minutes and reaches handling strength in about 30 - 40 minutes. Once fully cured, MMA 320 provides a strong, flexible bond that excels even under extreme hot or cold temperature ranges.

Note: MMA 320 is offered in black for applications requiring visual contrast.
