Non-Blushing Fast Hardener


The speediest hardener of our MAS Epoxies 2:1 Non-blushing System, Fast hardener gives you laminating power without the wait.  Since it’s part of our 2:1 system, it can be paired with LV Resin or FLAG Resin and mixed with our Medium and/or Slow Hardener as needed.  Additionally, at average temperatures you can re-coat with LV Resin and Fast Hardener in around 2 hours, which means you can get more done in a day, saving you time and energy.



  • No messy wash downs due to non-blushing properties
  • Clear finish means you get the structure and finish you want with one product
  • Fast gel time is great for small gluing projects and cool temperatures

    We'd recommend tenting the area you're working on and getting the space to at least 55F for ease of application. You may experience a cloudiness or the chemical reaction could stall out in temps below 50F. It would be advisable to try to keep it warm for as long as possible. Timing the repairs during peak warmth hours is recommended and giving it a longer post cure of  10-14 days before putting it into service could ensure better physical and mechanical properties of the repairs.

    LV stand for low viscosity, it will be a lot thinner than FLAG which stands for Filling Laminating and Glueing. Both have three different speed hardeners which you can combine to dial in an exact set time. Example, if you added a bit of fast to medium you could have gel-time in between the two given the amount you mixed.  

    Both are 100% solids no-voc formulas. In a well-ventilated environment standard PPE practices will apply.
