MAS Epoxy Slow Hardeners ONLY for FLAG and LV

MAS Slow Hardener is a 2:1 non-blushing hardener with a 30 minute working time at 70°F. It can be paired with the MAS LV Resin or Flag Resin and mixed with the 2:1 Medium Hardener and/or Fast Hardener, making it one of the most versatile epoxy hardeners on the market.  You get more time than with other supplier's "Slow Hardeners", so it's easier to work with in high temperatures and is great for beginners.
