Best Practices for Henkel Armstrong A-12T Epoxy Resin

*See Terms of Use Below
1. Mixing
  
  A-12T is a 2 part system (Part A and Part B), having a convenient and non-critical mixing ratio. High strength, permanent bonds are obtained by curing this adhesive either at room temperature or slightly elevated temperatures.
  
  The two components of the A-12T system are different colors, providing a visual indication of proper and complete mixing. Part A is dark brown, Part B is light gray.
  
  The most frequently used ratio is equal parts by weight.
  
  This is changed to vary the flexibility of the cured adhesive, with a ratio of 2 parts A to 3 parts B most common for flexible materials, or extreme vibration applications. In cryogenic applications the ratio may be as high as 1 Part A to 4 Part B. A rigid glue line results from a mixture of 3 parts A to 2 parts B. This also provides the highest strength in the 130° - 170°F range and is recommended where maximum chemical and solvent resistance is required or where high compressive forces exist.
